Disassembly Procedure
Caution: Refer to Brake Dust Caution in the Preface section.
Caution: Refer to Brake Fluid Irritant Caution in the Preface section.
Caution: Do not place your fingers in front of the piston in order
to catch or protect the piston while applying compressed air. This could result
in serious injury.
- Remove the brake caliper from the vehicle. Refer to
Front Brake Caliper Replacement
.
- Place a thin piece of wood in front of the piston in order to prevent
damage. Remove the piston by directing compressed air into the brake hose inlet
fitting port of the brake caliper housing.
- Remove
the piston boot.
- Remove the piston seal.
- Remove the brake caliper bleed screw cap.
- Remove the brake caliper bleed screw.
- Inspect the brake caliper bore and the piston seal groove for scoring
and corrosion. If you find excessive scoring or corrosion around the piston seal
area, replace the brake caliper housing.
- Inspect
the brake caliper mounting bracket guide surfaces for corrosion and wear. Remove
and replace the brake caliper mounting bracket if necessary.
- Clean all of the residue from the brake pad guiding surfaces on the brake
caliper housing and the brake caliper mounting bracket.
- Clean all of the parts not included in the repair kit with denatured
alcohol.
- Dry all of the parts with filtered unlubricated compressed air.
- Blow out all passages in the brake caliper housing and the brake caliper
bleeder valve.
Assembly Procedure
Notice: Refer to Fastener Notice in the Preface section.
- Install the brake caliper bleed screw.
Tighten
Tighten the brake caliper bleed screw to 12 N·m (106 lb in).
- Install the brake caliper bleed screw cap.
- Lubricate the new piston seals and the brake caliper bore seal grooves
with brake fluid.
- Install new seals into the brake caliper bore seal grooves.
- Ensure that the seals are not twisted.
- Lubricate the brake caliper bores and the pistons with brake fluid.
- Install the boot and piston.
7.1. | Install the boot over the end of the piston so that the fold will face
toward the brake caliper housing piston bore opening. |
7.2. | Seat the boot into the brake caliper bore groove. Slide the piston into
the brake caliper bore. |
7.3. | Push down the piston to the bottom of the brake caliper bore. |
7.4. | Ensure the boot seats properly into the piston groove and into the groove
in the brake caliper bore. |
7.5. | Repeat step 7 for the remaining piston. |
- Install the brake caliper to the vehicle. Refer to
Front Brake Caliper Replacement
