NOTES Notes on repairs to brake system   AH42.00-P-0003-01A
1 Assess lining thickness (1) of brake pads on front axle IMPORTANT If necessary, use lamp (2) or mirror (3). The thickness of the pad backing plate can be used as a guide when assessing brake lining thickness.  
Brake pad thickness
If, in exceptional cases, assessment by means of visual inspection is not possible,

remove wheels to conduct assessment, subject to separate repair order.

3 Determine likely remaining distance of brake linings   AP42.10-P-4253-03EW
IMPORTANT Per axle, the brake pad with the least lining thickness is to be used for determining likely remaining distance.
In order to avoid an unscheduled workshop visit between services, it is necessary to determine the remaining distance of the present brake linings. If the remaining distance determined is smaller than the next service interval, premature brake pad replacement should be recommended to the customer.
