3 Determine estimated remaining distance of brakepads. NOTES
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.
IMPORTANT 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.		 AP42.10-P-4253-03EW
