		If, in exceptional cases, assessment through visual inspection is not possible. ↓ Remove rear wheels and assess them. After obtaining special order.
3	Determine estimated remaining distance of brakepads..		AP42.10-P-4253-03EW
		If the wear limit for the brakepads has been reached, replace brakepads. After obtaining special order. Otherwise the braking effect may be impaired and people, property and environmental damage may result. To determine the estimated 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 existing brakepads. If the remaining distance determined is less than the next service interval, advise the customer to replace the brakepads before the due service date.
