REMOVAL & INSTALLATION
See Figures 1, 2, 3, 4, 5 and 6
- Siphon off 2 / 3 of the brake fluid from the master cylinder.
The insertion of the thicker replacement pads will push the caliper piston back into its bore and will cause a full master cylinder to overflow.
- Raise the rear of the vehicle and support it with safety stands. Remove the wheel and tire assembly.
- Remove the caliper as detailed later in this section.
- Remove the outboard brake shoe and lining by unsnapping the shoe springs from the caliper holes.
- From the inside of the caliper, press on the edge of the inboard brake shoe and tilt it outward so that it is released from the shoe retainer.
- Remove the flexible two way check valve from the end of the piston assembly with a small screwdriver.
If new shoes and linings are to be installed, remove the parking brake lever and bottom the piston in the caliper bore as shown in the accompanying illustration.To install:
- Lubricate a new two way check valve with silicone fluid and press it into the end of the piston.
- Install the inboard brake shoe. Make sure that the shoe retainer and the piston are positioned right. The tabs on the retainer are different; rotate the retainer into position if necessary. The buttons on the backing of the shoe must engage the larger, D-shaped notches in the piston. The piston will be properly aligned when the larger notches are aligned with the caliper mounting bolt holes as shown. Engage the inboard edge of the shoe with the straight tabs on the retainer, press downward and snap the shoe under the S-shaped tabs.
- Install the outboard brake shoe. The shoe is properly installed when the wear sensor is at the trailing edge of the shoe during forward rotation.
- Be sure to snap both shoe springs into the caliper holes so that the back of the shoe is flat against the caliper.
- Install the caliper.
- Bleed the brakes, install the wheels and lower the vehicle.
