Check

1

Assess bake lining thickness (1) of brake linings at front axle

 If necessary, use a flashlight (2) or a mirror (3). The thickness of the pad backing plate can be used as a reference when assessing the brake lining thickness (1).

If, in exceptional cases, assessment by means of visual inspection is not possible.



Remove front wheels and assess them subject to separate repair order.

2

Assess bake lining thickness (1) of brake linings at rear axle

 If necessary, use a flashlight (2) or a mirror (3). The thickness of the pad backing plate can be used as a reference when assessing the brake lining thickness (1).



Remove rear wheels and assess them subject to separate repair order.

3

Determine likely remaining distance of brake linings

AP42.10-P-4253-03EW


If the wear limit for the brake linings is reached, replace the brake linings subject to a separate repair order.
Otherwise the braking effect may be impaired and people, property and environmental damage may result.

 To determine the prospective remaining distance for each axle, refer to the brakepad with the least brakepad thickness (1).
In order to avoid an unscheduled workshop visit between services, determine the remaining distance of the present brakepads.
If the remaining distance determined is less than the next service interval, advise the customer to replaced the brakepads before the due service date.
