How to Use A Decelerometer For Trailer Brake Tests

Trailer maintenance requires to be as professional as truck maintenance, Carrying out a inspection brake test on trailer doe not mean an expensive Roller Brake Test.

Research has concluded that using a product like BrakeCheck to test trailers brakes is beneficial but will not indicate a below par efficiency on a particular wheel or brake, although using an Infra Red Thermometer as well will increase your awareness of a faulty brake or a low efficiency brake.

VOSA’s Mark Pattison has stated “A decelerometer is not the ideal method to test the braking of a vehicle and trailer combination. However it is of some use. You are correct that the checking of individual wheels would not show up in a test result. The way to use a decelerometer is to first test the drawing vehicle on its own. Then connect the trailer and the deceleration rate should be similar i.e. the trailer is doing its fair share of work. This is not an exact science but would be enough to give you confidence the trailer brakes were working.”

This system is ideal for commercial operations to improve maintenance records for trailers and increase awareness of a trailers brake performance between the annual roller brake tests. Offering a print out of the combination tractor and trailer performance with brake temperatures will improve quality procedures and health & safety paper work. It is often said in today’s age paper work to protect directors and managers from the corporate manslaughter or health and safety law is essential.
aide automotive have designed an inspection sheet for trailers using the BrakeCheck and thermometer, if you require a copy email info@aideautomotive.com with subject heading Trailer Inspection Sheet.

aide automotive also recommend to test the pressure on brake chambers, this will increase your past rate for trailer parking brakes.

aide automotives Brake Efficiency Tester BrakeCheck is the ideal way to test vehicle brakes.

VOSA are continually advising operators, commercial repairers and in house workshops to complete regular inspection sheet brake test.

Being electronic there is a much higher accuracy and additional information such as average deceleration, a left/right pull measurement, speed at braking and stopping distance. All tests are time and date stamped.

BrakeCheck can be used and is accepted by VOSA for many vehicles, in the commercial sector VOSA approve BrakeCheck for testing all commercial type vehicles on every inspection. Within the MOT centre this device is used as back up to the roller tester but used in principal on 4×4 vehicles.

Gary Moir of MSK Waste said ” Using a Brake Efficiceny Tester such as a BrakeCheck has saved this company hundreds of pounds as taking vehicles to rollers testers for an inspection brake test is unecessary.”

KNOW YOUR DIFFERENT ABS FLASH CODES FOR DIFFERENT MAKES OF SYSTEM

There are always two, possibly three, ways to power up the ABS system and you should know what to expect regarding light function. If an ABS/EBS cable is fitted then the GREEN headboard monitor lamp should be ignored and only look at the in-cab RED dashboard light. (The trailer light may not work at all with the ISO7638 connected)

STATIONARY TRAILER HEAD BOARD LAMP FUNCTION WHEN POWERED ONLY BY 24N STOP LIGHTS (REMOVE ALL OTHER CABLES)

The in-cab dashboard warning light will only work when the ABS Susie (ISO7638) or, in some cases, the 24S is connected. The lamp sequence will mimic the trailer headboard warning lamp when the ignition is turned on (NOTE: NO NEED TO PRESS FOOT BRAKE PEDAL)

** The first time after fitting a new ECU, this sequence is different until the vehicle has been driven above 30kph and the brought to a halt for dynamic sensor check. After this it should function as shown in table.

·         24Normal – ISO 1185

·         24 Supplementary – ISO3731

·         ABS/EBS – ISO7638

Brake Faults Most Common At the Roadside, says VOSA
Defective braking systems and components top the list of reasons for prohibitions issued by VOSA at the roadside and depot checks last year.

Nine percent of prohibitions for trucks and 20 percent of prohibitions for trailers were issued because of defective brakes.

The use of a regular deceleration test such as a BrakeCheck could help reduce brake faults and keep inspection sheet paper work in order.

BrakeCheck (decelerometer) can be used and is accepted by VOSA for many vehicles, in the commercial sector VOSA approve BrakeCheck for testing all commercial type vehicles on every inspection. BrakeCheck can be used on vehicles such as, fork lifts, construction / quarry vehicles, tractors and trailers.

This device has moved on significantly from the old mechanical testers such as Tapley Meters. Being electronic there is a much higher accuracy and additional information such as average deceleration, a left/right pull measurement, speed at braking and stopping distance. All tests are time and date stamped.

DOE Accpet Use of BrakeCheck For Irish Truck Operators & Repairers
After many years of use in England, Scotland and Wales we are pleased to advise the BrakeCheck decelerometer for use on commercial vehicles in Northern Ireland.

BrakeCheck has been proven to be an excellent inspection sheet brake tester for all commercial vehicles with over 11000 testers sold since 2002. With many commercial operators and repairers using the BrakeCheck to conduct a VOSA accepted brake test on every inspection, BrakeCheck is the number 1 decelerometer on the market today!

Richard Lee Compliant and Enforcement Manager of the DOE in Northern Ireland has recently accepted the use of a decelerometer for heavy goods inspection sheet brake testing. Richard states “I can confirm that a decelerometer may be adequate for checking brake efficiency on some vehicles especially if it is linked to a printer and a record of the brake test can be recorded. This would be consistent with our Guide to Maintaining Roadworthiness which has a section (5) detailing safety inspection and repair facilities.”

The DOE are now advising commercial vehicle operators, commercial repairers and in house workshops to complete regular inspection sheet brake test, The BrakeCheck is the tester! BrakeCheck will conduct a Service, Secondary & parking brake test with ease and store in its memory for later printing via PC or portable printer.

Commercial Vehicle Brake Testing

The following criteria are required for all HGV brake testing.

All brake testing should be carried out away from the sites working area; this should be done in an area that has roughly level ground.

The MOT performance figures are for the Peak Reading:

Service Brake Bare Minimum                        50%

Secondary Brake Bare Minimum                   25%

Parking Brake Bare Minimum                        16%

Although the test requirement looks for a peak reading, you could use the relationship between the peak and average to determine brake performance, if you achieved a peak reading of say 51  – 58 this is not indicating good brakes, peak figures of 70 + can be achieved to indicate good brakes, even though high peaks are recorded if a low average is recorded (20 – 30 example only) this would indicate bad brakes or you will more than likely fail a roller brake test!

Brake Tester Position

The brake tester should be positioned in the foot well of the vehicle, preferably up against a bulkhead with the direction of travel arrow pointing in the intended direction and with the tester straight.

Vehicle Test Procedure

With the vehicle stationary, position and arm the brake tester, accelerate the vehicle at a constant rate in a straight line up to a safe site speed then apply the brakes in an emergency stop manner, hold the vehicle on the brake until the vehicle has come to a complete rest.

Arming The Brake Tester

Turn the BrakeCheck on by pressing and holding MENU until Sbr is displayed on the screen. Press ENTER, the display will now show the level indicator L-| |-, if this is not the case re-position the BrakeCheck until achieved. Press ENTER the display should now read 0.00 ± 5. As described above accelerate and brake. The peak reading will report at the end of the test, if the display still shows L-| |- you did not press ENTER!!

With the Peak reading displayed press ENTER, this will show the average reading. Pressing ENTER again shows further information.

For a Hand Brake Test press MENU twice, this is while the service brake results are displayed; the display should now show Hbr. Now go to the second paragraph under “Arming The Brake Tester” to carry out a test.

For a Secondary Brake Test press MENU three times, this is while the hand brake results are displayed, and the display should now show SEc. Now go to the second paragraph under “Arming The Decelerometer” to carry out a test.

Printing Stored Tests

BrakeCheck has a 1 – TEST MEMORY on the Service Brake, Secondary Brake and the Hand Brake Test

The BrakeCheck can output test results to a printer if required. A cable is provided with the serial printer.

To Print using the Cable Connect the supplied cable of the printer with the BrakeCheck cable

To Print the Service Brake:

If the BrakeCheck has powered-down due to inactivity:

Press   until the display shows Sbr. Press  twice until the BrakeCheck display shows Sbr and the bottom half of the shows to
lights, one on Service Brake Test and the other on Last Test Result Press  once, (this is not necessary if the unit has
not powered-down) the Peak Deceleration (Front/Rear) LED will be lit and the display will show a value, eg:

Make sure all cables are connected and turn the printer on by pressing the button on the front of the printer, a green light should now flash.

If a red light is flashing the printer needs recharging!! If you have an orange flash your paper is getting low!!

Press   once, the display will show: and the printer will print the results for the last test performed.

Now do the same for the Hand Brake or the Secondary Brake, but have the Hand brake test light and Last Test Result illuminated on the
BrakeCheck or the Service, Hand Brake & Last Test Result illuminated for the Secondary Brake .
