HGV  / Commercial Vehicle Brake Testing 

September 3rd, 2019 Comments off

Although the DVSA states a preference for roller brake testers during safety inspections, it does allow the use of portable decelerometers. What are their advantages and limitations of using portable decelerometers?

Every safety inspection must assess the braking performance of a vehicle or trailer. It’s a key part of any maintenance regime and demonstrates that operators are running their fleets in a compliant manner and protecting other road users. The DVSA’s Guide to Maintaining Roadworthiness states that using an approved and calibrated decelerometer is acceptable to measure overall brake efficiency values for vehicles as part of the yearly maintenance scheme.

We do hear that testers are “strongly advised” to use a calibrated roller brake tester (RBT) at each safety inspection to measure individual brake performance and overall braking efficiencies for the vehicle or trailer according to the annual test standards.

Why is this? And when should each type be used?

There are two main types of portable decelerometer: digital and mechanical. Both are straightforward to use, although care has to be taken: “To use a decelerometer, the vehicle must be driven on the road, or in a yard with enough space. This should be a good surface, which is suitable in wet or dry conditions, with little traffic.

As the guidance states the use of an RBT or calibrated decelerometer can be used, it is obvious to most that a roller brake tester is far better way of determining brake efficiency. Very true would be an educated response although a combination of Roller Brake Tests and regular decelerometers test is as good a record of brake tests as possibly can be offered.

So is a portable decelerometer vulnerable to mis-testing?, a DVSA spokesman explains: “Anecdotally, the DVSA is aware of potential risks due to user error, although the DVSA has no data on this. Also, roller brake testing provides a more consistent test, whereas decelerometer use may involve some environmental variations such as test speed, road surface, weather, or gradient of the road.”

Speaking about the restriction on using decelerometers with tractor-trailer combinations, the spokesman adds: “Assessing different parts of a tractor and trailer combination can be difficult with only a decelerometer. For this reason, rigid vehicles such as buses and non-articulated lorries are more acceptable uses of decelerometers.”

The DVSA spokesman says that manufacturers provide guidance on the use of decelerometers. Risk assessments need to be in place where decelerometers are being used for brake testing, and the tests must be carried out under controlled and safe conditions.

Another decelerometer supplier is Bowmonk. Its portable brake testing kit, BrakeCheck, is also approved by the DVSA. Bowmonk says RBTs are not more accurate, but are preferred for annual tests because they “provide a means of recording each individual brake performance, whereas a decelerometer records the overall braking performance”. He adds: ”DVSA allows all operators to use a BrakeCheck for all of their interim brake tests that form part of their scheduled safety inspections.”

Bowmonk’s equipment was approved because it was able to demonstrate that the readings of overall braking efficiency and percentage of braking imbalance recorded by the device were within a specified level of tolerance, compared to that of an RBT. “BrakeCheck records the rate of acceleration from vehicle rest to the point where the brakes are applied. At this point it detects the forces being shifted forward, and then records the rate of deceleration to the point where the vehicle comes to a complete stop. From this, BrakeCheck then calculates the stopping distance, test speed and ultimately the braking efficiency.”

Any competent vehicle technician can use a BrakeCheck decelerometer without training, although training can be offered.

Adds Dave Wood, DVSA enforcement policy manager: “Under controlled and limited situations, decelerometer testing still has a place. As electronic braking performance monitoring systems gain popularity, we would like to encourage operators to use such systems as part of their vehicle defect monitoring and maintenance regime.”

FIXED BRAKE TESTERS

DVSA says it strongly advises calibrated RBTs “because this is the method of brake testing used by the MOT and is supported by legislation“.

Steve Coles, head of MOT operations at the Retail Motor Industry Federation, confirms that an RBT measures a greater number of elements of brake performance than a decelerometer. He states: “Performance efficiency, binding, fluctuation, increase and reduction of brake effort can all be measured, whereas a decelerometer can only check efficiency and a very rudimentary check of imbalance, which is subjective rather than measured.”

One reason DVSA prefers RBTs is road safety: “Having vehicles conduct emergency stops on public roads using a decelerometer carries a certain risk to other road users that is alleviated if the vehicle is tested in a workshop using an RBT.”

Approved MOT stations must have a fixed brake tester, either roller brake (pictured above) or plate brake tester. Boston’s Tabor says: “Roller brake testers are the most commonly used, since they require less space. The only exception to a fixed brake tester may be a remote part of the country, for example some Scottish islands, but this is rare, if not now a discontinued practice.”

To meet DVSA criteria, all equipment used in the test lane – fixed or otherwise – has to be approved by, for example, the Garage Equipment Association (list of approved equipment: ). Explains Tabor: “The reason for this is to make sure that regardless of where the vehicle is tested and on what make of equipment, the result will be the same. To maintain accuracy, fixed brake testers must be calibrated every six months and certificates to prove accuracy are issued to the test station. Decelerometers must meet mandatory standards and also need calibrating every two years. The longer period between calibrations is because they are only there for temporary use.”

FURTHER INFORMATION

For a meaningful brake test, DVSA recommends that the vehicle should be at least 65% loaded, where possible.

BOX: CRIME AND PUNISHMENT

In 2017, the boss of Grittenham Haulage and its mechanic were jailed after one of their tipper trucks crashed, killing four people, due to faulty brakes. The judge at Bristol Crown Court said Matthew Gordon and Peter Wood had a “cavalier“ attitude to vehicle maintenance at their firm before the incident in 2015.

Gordon told the court that he had been unaware brake checks had to be carried out every four months and admitted that he didn’t have a transport manager in place. Gordon was jailed for more than seven years; Wood for more than five.

After the sentencing, DCI Richard Ocone said: “Detailed and complex investigations showed many of the faults on the vehicle were longstanding – highlighted by the fact that the brakes on the lorry at the time of the crash were totally inadequate, having an overall efficiency of just 28%.”

ISO7638 Truck & Trailer Tester

July 19th, 2019 Comments off

#Commercial #Vehicle Workshop is a business magazine for companies and individuals involved in all aspects of commercial vehicle servicing.

#Trailer #Servicing & fault finding was featured in the recent July issue with an advert from aide automotive detailing the #ISOCheck.

ISOCheck EBS will test all electronic braking systems, #Wabco, Knorr #Bremse and #Haldex, covering the differences between the early generations and the latest.

ISOCheck really becomes the perfect test tool on a dark wet night, the quick test and the bright (Green) OK / Fault (Red) answer increases test and repair efficiency.

ISOCheck can be used as a constant visual aide on any truck and trailer but possibly especially for double decker trailers. Double decker trailers with a defective EBS system would vastly increase the chances of roll over or jack-knife. With ISOCheck in place a driver or depot gateman would be able to see the RED warning light.

To read the full article on Trailer Servicing, go to the CVW Magazine website to review an online copy.

Agricultural tractor Brake Test would meet the road worthines

Tractors To Require An O Licence

Agricultural tractors “likely” to require an O-licence

aide automotive have recently seen media reports of agricultural vehicles possibly being made to meet better road safety regulations as per commercial vehicles on UK roads.
Commercial Motor published:
Agricultural tractors that carry out commercial haulage will be subject to roadworthiness testing requirements from next year – and are likely to fall under the O-licensing regime.
From 20 May 2018, operators of agricultural tractors capable of travelling more than 40km/h (approximately 25mph), used to carry commercial goods, will be required to undergo a roadworthiness test four years after their registration and every two years thereafter.
In its response to a consultation carried out last year, the DfT also noted that operators of such tractors would likely require an O-licence.
However, the RHA said the changes did not go far enough to address the concerns about competition, and said allowing tractors to carry freight will encourage more to be used for haulage.
“Ideally we would like to see these vehicles banned from moving freight on public roads entirely as their design is not equivalent to well-designed lorries for that task,” said policy director Duncan Buchanan.
“We do not believe that the frequency, four years for the first test then every two years, is justified. It looks very odd for heavy vehicles like these to be tested so infrequently when a 50cc moped is required to be tested every year after three years.”
The FTA’s head of policy and compliance information, James Firth, added: “If it looks like a truck or it’s doing the work of a truck, test it like a truck. Members in areas where agriculture is a primary economy have long raised concerns that agricultural tractor units, and specially developed fast tractors, were competing in the haulage market without being burdened by the same safety standards.”
On the subject of O-licensing, Buchanan added: “If it is the case then operators would need to obtain O-licences from when the vehicle was new. They should also have to comply with the same level of rigour as lorries.”
Vernon Hill, director at Kings Lynn-based Vernon Hill Agricultural Services, supported bringing tractors into the O-licensing regime.
He said: “An agricultural contractor friend of mine who runs lorries and tractors thinks the cost of each is very similar, so if farmers think they are saving money by not using a haulier they may be kidding themselves.
“If they are doing commercial haulage, why shouldn’t they be in scope of O-licensing?”
The weight and speed limits for farm tractors and trailers on UK roads increased in 2015. Tractors are not currently subject to mandatory testing.
If tractors are to fall under the O licence criteria, agricultural workshops and repair engineers will have to look at regular brake testing, one way to test tractor brakes is the BrakeCheck decelerometer.
Easy to use and with hard copy print options, brake testing a agricultural tractor with a BrakeCheck would meet the road worthiness requirement of an O licence.

Truck ISO ABS / EBS Susie – What Is It?

November 29th, 2017 Comments off

Faulty ISO7638 Line Can Cause Fatal Accidents

Some drivers aren’t aware of the role Of the ISO ABS / EBS Susie!

aide automotive have seen recent reports in the media of articualted truck drivers knwloedge of the ISO 7638 Susie.
We offer credit to the below article to Don Bur Ltd.
There is disturbing evidence to suggest that some drivers aren’t aware of the role and critical importance of the ABS ISO7638 line for articulated trailerswhilst in transit or, more worryingly, are deliberately leaving it disconnected.
The use of the ABS ISO7638 line (otherwise known as the EBS/ABS line) became law in May 2002 where the tractor and trailer are both provided with connections.
The EBS/ABS ‘Suzie’ connection provides electrical and data feeds to the trailer’s ECU or ‘brain’. The ECU then controls the anti-lock braking system (ABS), load sensing (LSV), roll stability (RSS) and suspension control which regulates the correct trailer ride height and, in turn, the overall trailer height.
So why then might a driver leave it disconnected? There are, surprisingly, a couple of reasons. Firstly, the roll stability system (RSS) automatically applies the brakes if the trailer is going too fast round a bend. This has an impact on both speed and fuel economy and, if a driver is either in a rush or targeted against fuel consumption, they might be tempted to disable this ‘inconvenient’ feature.
The other apathetically induced reason is that it just “doesn’t seem to do anything”. Indeed, when the driver pulls away, his/her brakes and lights will appear to work. What the driver may not understand is that they are more likely to experience jack-knifing, aquaplaning, brake lock, rollover, bridge strike and, more commonly, the fact that the 44T rig just won’t be able to stop as quickly when trying to avoid that pram that’s just peeked out from a line of parked cars.
So, just in case there is any lingering doubt, failure to connect the ABS ISO7638 line correctly results in the risk of catastrophic, life-threatening accidents. If the driver fails to use the line/ ‘Suzie’ correctly and there is a collision in which someone is killed, then the driver can face a charge of manslaughter.
aide automotive market a ISO7638 cable with fault indicator, so as well as having the cable correctly connected a driver can also be notified of any faults within the system. Again an electrical fault could have the same catastrophic effects as the ISO Susie cable being non connected.
ISOCheck lights bright RED when a fault is identified, if good to go the ISOCheck is continually lit bright GREEN.

80% Of Commercial Vehicle Brake Faults Cleared By Sensor Master

November 7th, 2017 Comments off

CV ABS & EBS Brake Repairs Made Easy!

The Sensor Master Clears 80% Of Commercial Vehicle Brake Faults

As the air braking world has changed, we have had to adapt the way we deal with diagnostic problems that can arise on our customers vehicle systems. As the air signalling system has been fazed out and replaced by the EBS / ABS system we have endeavored to keep up with the advancements in the technology and created our own range of testing equipment.
Our engineer is constantly updating the test equipment to match the needs that arise from his service visits, so are perfectly tuned to the EBS / ABS components that we supply.
Our test devices can be used in conjunction with the OE manufacturer’s testers to create a complete analysis structure for truck and trailers that is not only easy to use but also affordable to all sizes of fleet maintenance from owner / driver to multi fleet service garages.
Since 80% of all EBS / ABS problems are sensor related (Reported By Knorr Bremse & Wabco), by connecting to the sensor socket on each wheel, rather than the ECU, in effect, taking the quickest and most direct route, by going straight to the heart of the problem.
The Sensor Master DRA08 is a handheld EBS / ABS sensor and exciter ring tester, for use on trucks, trailers, and buses.
Lightweight and portable, the EBS /ABS CV Sensor Tester comes supplied with two 1.6m high quality cables, a sturdy carry case, short introductory printed manual, and a single 9V battery – everything, in fact, needed to use it straight out of the box.
Designed with ease of use in mind, the Commercial Vehicle ABS EBS Sensor Testertakes minutes to set-up, and, once connected, undertakes a complete test cycle of the six most common causes of EBS / ABS faults, at the touch of a button, in just 15 seconds – a fraction of the time it would take to perform the same tests manually.

Electronic Brake System (EBS) Trailer Testing With ISOCheck

What Is The ISO EBS Truck & Trailer Lead

How does the EBS truck & trailer Susie lead work?
Everyone seems to have there own ideas how it works, ranging from; “if it’s not plugged in your trailer brakes wont work”, & “it’s only a back up power anyway”
Both are incorrect!
The truth is…
The Electronic Braking System (EBS) Susie or the ISO 7638 (its correct name) is essential for the trailers Electronic Braking System (EBS) to operate correctly.
So, if a truck has an ISO7638 socket a tractor and trailer must be connected with an ISO7638 Susie and the EBS must be working correctly!
Also this means the EBS warning light the truck operator should be checking is in the cab and not the one on the trailer headboard (if there is one).
This is where the problems start, how does the EBS lead actually work, well this is how:
Pin 1 in most trucks is permanent live
Pin 2 is switched ignition live
Pin 3 is common return to battery negative
Pin 4 is common return to battery negative
Pin 5 is the warning light control (positive)
Pin 6 is “CAN” High
pIn 7 is “CAN” Low
Pin 5 which is the warning light control wire, this pin seems to be continually misunderstood. Some people think pin 5 is controlled by the trucks EBS system or even by the truck itself, both of these are incorrect, how it works is quite simple, a basic explanation is detailed below:
Power from the truck battery routes to a fuse, then to the ignition switch and then to the warning light in the dash board, finally then to pin 5 in the socket.
When an EBS Susie ISO7638 lead is connected to the trailer the trailer EBS system sees 24 volts down pin 5, which and then reduces that voltage inside the trailer ECU to below 5 volts (earth) which then activates the EBS light on in the truck cab.
Once a truck & trailer is in motion and the the trailer EBS system is happy with the wheel speed signals, the ecu then raises the voltage back up to 24 volts and the warning light in the cab goes out, if a fault appears when a truck & trailer is on the road, the ecu lowers the voltage again activating the In Cab Warning Light.(Please Note This Is a Basic Description).
An easy way to test the truck & trailer ISO Connection socket is the ISOCheck
The Electronic Braking System (EBS) Susie or the ISO 7638

CV Traffic Commissioners Review & Advice

Read Some Highlights OF TC’s Annual Report for 2015-16

Recently reported in the Transport Operator, the seven traffic commissioners (TCs) of Great Britain have released their annual report for 2015-16, highlighting a broad range of transport compliance and enforcement issues identified during the course of the year, and their priorities for future progress.

The commissioners, who preside over the eight regional traffic areas, identified key concerns with regard to operator compliance, driving and maintenance standards, as well as problem areas for the authorities themselves to tackle in order to improve the services they offer.

TC Richard Turfitt, who oversees the largest traffic area, in the east of England, said he made little apology for “sounding like a broken record” when it came to vehicle inspections.

“As DVSA estimates that half of MoT fails could be avoided by checking that light-bulbs work, the condition and pressures of tyres and that mirrors, wipers and washers work, there is further work to do,” he said.

“I am appalled by the number of operators who have not even checked whether their inspection sheets are up to date by reference to DVSA’s Guide to Maintaining Roadworthiness.

“In the space of two weeks, two unconnected operators appeared before me suggesting their vehicles were being inspected against safety standards from 1972.”

May 19th, 2017 Comments off

aide automotive launches improved ISOCheck

EBS ISOCheck Now Available In Addition To the ABS ISOCheck – Review Products Details & Buy Online

Commercial Vehicle Equipment Supplier aide automotive Has Launched An Updated Version Of The ISOCheck

ISOCheck tests a trucks’ ISO sockets in order to help identify ABS or EBS faults.

 

The latest iteration of the system – ISOCheck EBS – has been designed to test electronic braking systems incorporating a CAN line test.

“Trucks that were first used on or after 1 May 2002 must be fitted with A ISO 7638 connection,”

“If a truck is fitted with an Electronic Brake System, and is also towing a trailer that is fitted with EBS, then a 7-core cable must be used.

Like the ISOCheck ABS tester, ISOCheck EBS tests the ISO Socket 7638 pins 1 to 5, but also tests pins 6 and 7, the EBS CAN lines.

Alongside the standard ABS & EBS ISOChecks we can also offer a diagnostic EBS ISOCheck.

ISOCheck EBSPlus test pins 1 to 7, and identifies the exact pin at fault.

Once the initial power test is complete with a RED fault light, the ISOCheck will then go into diagnostic mode and flash a count sequence in relation to the faulty pin,

The ISOCheck product range has benefited from a complete redesign, incorporating the latest electronics technology which enables future proofing truck and trailer brake systems.

ISOCheck can be used to test all Wabco, Knorr-Bremse and Haldex systems, from the early generations to the latest.

Testing is simple and easy,

ISOCheck can be used in many ways: fault-finding by the roadside or as an inspection sheet test within a workshop.

ISOCheck really becomes the perfect test tool on a dark wet night. The quick test and the bright (GREEN) OK / (RED) FAULT indicator increases test and repair efficiency.

The system can also be used continuously between a unit and trailer as a constant visual aide.
