BRAKE PADS

PAD REMOVAL

1. Loosen the (4) wheel nuts.
2. Elevate and support the side of the ATV in which the
caliper brake pads are being serviced.
CAUTION
Use care when supporting vehicle so that it does not tip
or fall. Severe injury may occur if machine tips or falls.
3. Remove the wheel nuts and wheel.
4. Remove the (2) brake caliper mounting bolts and
caliper.
5. Push mounting bracket inward and slip the outer
brake pad past the edge of the pin. Remove the
inner brake pad.

PAD INSPECTION

1. Measure the thickness of the pad material by taking
two measurements. Measure the thickness of the
friction material and backing plate, then measure the
thickness of just the backing plate. Subtract the
backing plate thickness from the plate and friction
thickness to get the thickness of just the pad friction
material. Compare to the specification. Replace pads
if worn thinner than the service limit.

Service Limit: .030" (.762 mm)

PAD INSTALLATION

1. Lubricate mounting bracket pins and external slide
pin O-ring with a light film of silicone grease.
2. Compress mounting bracket. Install pads with friction
material facing each other.
WARNING
If the brake pads are contaminated with grease, oil, or
liquid soaked do not use the pads.
Use only new clean brake pads.
