On-Vehicle Service

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.
- It is not necessary to remove connecting bolt except for disassembly or 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 brake rotors, after replacing pads, or if a soft pedal occurs at very low mileage.

INSPECTION
Pad Thickness





- Remove a wheel with the vehicle lifted up, and then check the thickness of the pad from the inspection hole of the cylinder body. If necessary, check it with a scale.
Standard pad thickness: 8 mm (0.31 inch)
Pad wear limit: 1.5 mm (0.059 inch)

PAD REPLACEMENT
Removal
- If shims are rusted or show peeling of the rubber coat, replace them with new shims.
- Whenever the brake pads are replaced, the inner shim, the outer shim and the shim cover have to be replaced as a set.





1. Remove master cylinder reservoir cap.
2. Remove lower pin bolt, using power fool.





3. Open cylinder body upward and secure with wire. Then remove pad retainers, and inner and outer shims.

Installation
1. Apply grease to the inner and outer shim, and then attach them to the pads.
2. Attach the pad retainer to the torque member, and then attach it to the pad.
3. When installing new pads, push piston back into cylinder body.
- Carefully monitor brake fluid level because brake fluid will return to the reservoir when pushing back piston.
4. Close cylinder body down into the torque member.
5. Insert a main pin bolt and tighten it to specified torque.
6. Check the brake for drag.

CAUTION: Burnish the brake contact surfaces refinishing or replacing brake rotors, after replacing pads, or if a soft pedal occurs at very low mileage.
