Measuring procedure
Make sure that the prerequisites
according to the previous page are met.
1 Select AXLES/BRAKES from the
keyboard .
2 Select the sub menu BRAKE TEST
with the arrow key.
3 Move off (gear selector position A).
When the speed exceeds 20 km/h (12.4
mph) there will be a short pip signal and
the display unit will show "0.0 m/s
2
0.00
g", which means that the speed required
for the test has been reached.
4 If the display unit instead shows "X.X m/s
2
X.XX g",
the speed is too low (below 20 km/h = 12.4 mph).
To obtain credible and useful test values, the
brake application must be carried out:
• Without wheels locking or skidding.
• With the brakes applied as hard as possible and
without letting up the brake pedal during the test.
Result and evaluation
The test result will be shown on the display unit when
the machine has stopped, i.e. the speed is 0 km/h,
and remains on the display until the speed again
exceeds 10 km/h (6.2 mph).
In order to eliminate tests during which the wheels
have locked , brake applications where the retardation
exceeds 8 m/s
2
(0.82 g) are not registered.
In this case "X.X m/s
2
X.XX g" will be shown on the
display unit.
Minimum value for brake test: 4.75 m/s
2
(0.48 g)
• If the measured retardation is less than 4.75 m/s
2
(0.48 g), a new test has to be carried out.
If this test too shows a value below 4.75 m/s
2
(0.48
g), the brake system must be checked at an
authorised workshop.
