Assembly Procedure
WARNING: This page is about a different car, the 2009 GMC Sierra, 2009 GMC Cab & Chassis Sierra, 2009 Chevrolet Silverado, and 2009 Chevrolet Cab & Chassis Silverado. However, it is still accessible from the selected car via links, so may be relevant.
- Apply a small amount of clean DOT-3 brake fluid to the piston, piston seal, and piston bore.
- Install the square-cut piston seal in the brake caliper bore groove.
- Ensure the square-cut piston seal is not twisted.
- Install the boot over the end of the piston so the fold will face toward the brake caliper housing piston bore opening.
- Position the piston to the brake caliper bore and seat the boot into the brake caliper bore groove.
- Position a piece of wood across the piston to be installed.
- Applying equal pressure by hand while pushing down, install the piston in the bore.
- Remove the piece of wood.
- Install the bleeder valve in the brake caliper housing.
Tighten: Tighten the bleeder valve to 12 N.m (106 lb in).
- Install the bleeder valve cap.
- Install the brake caliper. Refer to Rear Brake Caliper Replacement (JD9) or Rear Brake Caliper Replacement (JH6, JH7) .
NOTE:
When applying the clean brake fluid to the piston bores, piston seals and pistons, only apply the brake fluid to one bore at a time. This is done to ensure the brake caliper, seals and pistons DO NOT become contaminated with dirt or other foreign material.
NOTE:
Position the piston in the bore so that it is straight and level.
CAUTION:
Refer to Fastener Caution
