Exploded View Of Rear Brake Caliper:

NOTE: Numbers in parentheses ( ) below refer to numbers in the illustration.

CAUTION: Do not separate caliper halves.

DISASSEMBLE
1. Clean outer surfaces of caliper with suitable brake cleaner.





2. Expel pistons (5) from their bores by applying air pressure to fluid inlet port.

NOTE: It is unlikely both pistons will expel at same time, regulate rate with a suitable piece of wood inserted between two pistons.

3. Remove pistons (5) keeping them identified with their respective bores.
4. Remove wiper seal retainer (6) by inserting a blunt screwdriver between retainer and seal and pry retainer carefully from mouth of bore.
5. Taking care not to damage seal grooves, extract wiper seal (7) and fluid seal (8).
6. Clean bores, pistons and particularly seal grooves using clean brake fluid only.

NOTE: If caliper or pistons are corroded or their condition is not perfect, new parts must be installed.

ASSEMBLE
1. Apply brake fluid to new fluid seal, then install into groove in bore.

NOTE: When seal is seated it feels raised to touch at edge furthest away from mouth of bore.

2. Coat piston (5) with brake fluid. Insert it squarely into bore.

NOTE: Do not tilt piston during insertion and leave 8mm (0.2 inch) projecting from bore.


3. Coat a new wiper seal (7) with brake fluid and install to new seal retainer (6).
4. Slide seal and retainer assembly (6 and 7), seal first, over protruding piston into bore recess.
5. Using piston clamp tool No. LRT-70-500, or equivalent, press home seal retainer and piston.
6. Repeat procedure to install opposing piston.
