	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 guide when assessing brake lining thickness (1).
		Front axle Brake lining If, in exceptional cases, assessment by means of visual inspection is not possible. ↓ Detach wheel and tire assemblies and inspect them, subject to separate repair order.	BE42.10-P-1001-05U
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 guide when assessing brake lining thickness (1).
		Rear axle Brake lining If, in exceptional cases, assessment by mean; of visual inspection is not possible. ↓ Detach wheel and tire assemblies and inspect them, subject to separate repair order.	BE42.10-P-1001-15R
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.
