Refer to Brake Dust Warning .
Refer to Brake Fluid Irritant Warning .
- Replace all the components included in the repair kits used to service this brake caliper.
- Lubricate the rubber parts with clean brake fluid to make assembly easier.
- The torque values specified are for dry, non lubricated fasteners.
- Perform the service operations on a clean bench, free from all mineral oil materials.
Remove the rear brake caliper and bracket assembly (1). Rear Brake Caliper Replacement (JH6) , or Rear Brake Caliper Replacement (JH9)

- Place a wood block between the brake caliper pistons and the brake caliper housing bridge.
- WARNING:
Do not place fingers in front of the caliper piston(s) in an attempt to catch or protect it when applying compressed air. The piston(s) can fly out with force and could result in serious bodily injury.
Carefully remove the brake caliper piston by directing low pressure compressed air into the brake caliper inlet hole.(1)
Rear Brake Caliper Piston Boot(1) - Remove[2x]
- Rear Brake Caliper Piston Seal(2) - Remove[2x]
Rear Brake Bleeder Valve Cap(1) - Remove
- Rear Brake Caliper Bleeder Valve (2) - Remove
- Inspect the brake caliper bore and the piston seal groove for scoring and corrosion. If you find scoring or corrosion around the piston seal area, replace the brake caliper housing.
- Clean the brake caliper piston bore and seal counterbore, and the caliper piston with denatured alcohol, or equivalent.
- Dry all of the parts with filtered compressed air.
- Blow out all passages in the brake caliper housing and the brake caliper bleeder valve.
Do not place fingers in front of the caliper piston(s) in an attempt to catch or protect it when applying compressed air. The piston(s) can fly out with force and could result in serious bodily injury.
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.
