25.2 PAD
REPLACEMENT PROCEDURE
Brake pad replacement procedure has slightly
changed with the introduction of brakes with
improved slack adjusters on our vehicles.
After fitting new pads, adjuster has to be turned
clockwise until pads come in contact with the
disc. Then turn anti-clockwise
three clicks
to
give the correct running clearance.
Please refer to
Knorr-Bremse Y006471
Service Manual, Section 6
for the latest brake
pad replacement procedure.
25.3
CHECKING DISC BRAKE PADS
Brake pads have to be checked on a regular
basis depending on the vehicle operation. The
remaining thickness of the pads should never be
less than 0.079 in (2 mm). When replacing brake
pads, all four pads on an axle have to be
changed at the same time. There is no inner or
outer pad, since all pads are the same.
Once removed, worn pads should be replaced in
their original position. Please refer to Knorr-
Bremse Y006471 Service Manual for further
detail.
25.3.1 Drive Axle – Equipped With L-bracket
Wear Indicator
The condition of the pads can quickly be
checked without removing the wheel by
checking the position of the caliper compared to
the tip of the wear indicator.
