Disassembly Procedure
- Remove the rear brake caliper. Refer to
Rear Brake Caliper Replacement
.
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.
Notice: Use clean cloths to pad interior of caliper housing during piston removal.
Use just enough air to ease the pistons out of the bores. If the pistons are
blown out, even with the padding provided, it may be damaged.
- Remove the piston. Blow compressed air (3) into the caliper
inlet hole. The piston will come out through the piston boot.
- Inspect the piston for the following conditions:
• | Replace the piston if any of the above conditions are found. |
- Remove the piston boot (2).
Use a flat-bladed tool in order to lift one end of the boot ring. The piston
boot ring may be stuck in the caliper groove.
Notice: Do not use a metal tool for seal removal. Damage to the caliper bore
or the seal grooves can result.
- Remove the piston seal (4) from the groove in the caliper body (3).
Use a small wooden or plastic tool in order to manipulate the piston seal
out of the caliper bore groove.
- Remove the bleeder valve cap (1), the bleeder valve (2)
from the caliper housing.
- Inspect the caliper bore and the seal grooves for the following
conditions:
- Replace the caliper housing if corrosion in and around the seal
groove cannot be cleaned with a crocus cloth. Do not hone the caliper bore.
- Clean all the parts in clean, denatured alcohol.
- Dry all the parts with filtered, non-lubricated compressed air.
- Blow out all the passages in the caliper housing and the bleeder
valve. Use filtered, non-lubricated compressed air.

Notice: Use the correct fastener in the correct location. Replacement fasteners
must be the correct part number for that application. Fasteners requiring
replacement or fasteners requiring the use of thread locking compound or sealant
are identified in the service procedure. Do not use paints, lubricants, or
corrosion inhibitors on fasteners or fastener joint surfaces unless specified.
These coatings affect fastener torque and joint clamping force and may damage
the fastener. Use the correct tightening sequence and specifications when
installing fasteners in order to avoid damage to parts and systems.
- Install the bleeder
valve (2) and the bleeder valve cap (1) to the caliper
housing.
Tighten
Tighten the bleeder valve to 11 N·m(97 lb in).
- Lubricate a new piston seal with clean
brake fluid.
- Install the piston seal into the caliper bore grooves. Ensure
that the piston seal is not twisted.
- Lubricate the piston boot with clean brake fluid.
- Install the piston boot (1) onto the piston (2).
- Lubricate the piston OD with clean brake fluid.
- Install the piston and the boot into
the bore of the caliper using the J 36349
.
7.1. | Ensure that the outside edge of the piston boot is seated smoothly
in the counterbore of the caliper body. |
7.2. | Lift the inner edge of the piston boot next to the piston. Press
out any trapped air. Ensure that the boot lies flat. |
- Install the rear brake caliper. Refer to
