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 may well show GPS flashing (Setup Mode also flashes), if so the BrakeCheck is now in GPS location mode, once the BrakeCheck has found the satellites then the test will move onto the level indicator.
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.
Printing Stored Tests
BrakeCheck GEO has a 99-test memory on the service and hand brake tests; the tests are stored in the memory by the latest test completed being test number 1.
Printing is via Infra-red! No cable required.
Point the front of the BrakeCheck at the front of the printer.
To Print the Service Brake:
If the BrakeCheck has powered-down due to inactivity:
Press MENU until the display shows Sbr.
Press MENU 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 ENTER once, the display will show L n, press MENU the display will show L A (pressing ENTER now will print off all tests in the memory), Press MENU and the display will show L 1, pressing MENU will increase the test number by ONE, holding down MENU will increase the test number at a rapid rate:
With the desired test number on the display press ENTER, the Peak Reading will be displayed, with the printer switched on and the BrakeCheck pointed at the printer press PRINT. Each print out will take roughly 10 seconds to print. 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: 0.86
Turn the printer on by pressing the grey M button on the front of the printer, a green light should now be on! If a green light is flashing the printer needs recharging or paper is low!!
Press PRINT once, the display will show: Prt
and the printer will print the results for the last test performed. Now do the same for the Hand Brake but have the Hand brake test light and Last Test Result illuminated on the BrakeCheck.
