Pad Replacement

WARNING:
Clean brake pads with a vacuum dust collector to minimize
the hazard of airborne particles or other materials.
CAUTION:

●

When cylinder body is open, do not depress brake pedal
because piston will pop out.

●

Be careful not to damage piston boot or get oil on rotor.
Always replace shims in replacing pads.

●

If shims are rusted or show peeling of rubber coat,
replace them with new shims.

●

It is not necessary to remove connecting bolt except for
replacement of caliper assembly. In this case, suspend
cylinder body with wire so as not to stretch brake hose.

●

Burnish the brake contact surfaces after refinishing or
replacing rotors, after replacing pads, or if a soft pedal
occurs at very low mileage.
Refer to “Brake Burnishing Procedure”, “ON-VEHICLE
SERVICE”, BR-7.
