Repair Instructions
Brake Pad Inspection
• Inspect the disc brake pads every
10,000 km (6,000 miles) and anytime the
wheels are removed.
Brakes
• Inspect both ends ofthe outer pad by looking in at
each end of the caliper. The highest rate of wear
normally occurs at the ends.
• Inspect the thickness of the inner pad in order to
ensure that it has not worn prematurely. Look
through the window in the top of the caliper
in order to view the inner pad.
• Both front and rear disc brakes have wear
indicators that make a noise when the pads wear
below specifications. The wear indicator is an
integral part of the outer pad. When the pad
is worn the wear indicator contacts the rotor and
produces a warning noise as indicated in the
illustration above.
• Replace the pads when the thickness is worn
below specification. Replace all pads in axle sets.
Refer to Component Specifications.
• Measure the flatness of the inner and outer pads;
Place the pad surfaces together and measure
the gap between the surfaces. If a gap larger than
the specification exists midway between the
(
attaching lugs, replace the pads. Refer to
(
Component Specifications.
