Front Brake Caliper Replacement Single Piston
Removal Procedure
Caution: Refer to Brake Dust Caution in the Preface section.
Caution: Refer to Brake Fluid Irritant Caution in the Preface section.
Notice: Refer to Brake Fluid Effects on Paint and Electrical Components Notice in the Preface section.
- Inspect the fluid level in the brake master
cylinder reservoir.
- If the brake fluid level is midway between the maximum full point and
the minimum allowable level, no brake fluid needs to be removed from the reservoir
before proceeding.
- If the brake fluid level is higher than
midway between the maximum full point and the minimum allowable level, using an
appropriate tool, remove the brake fluid to the midway point before proceeding.
- Raise the vehicle. Refer to
Lifting and Jacking the Vehicle
in General Information.
- Remove the tire and wheel assembly. Refer to
Tire and Wheel Removal and Installation
in Tires and Wheels.
- Compress the front caliper piston.
• | Install a large C-clamp over the top of the caliper housing and against
the back of the outboard pad. |
• | Slowly tighten the C-clamp until the piston is fully seated in the brake
caliper bore. |
• | Remove the C-clamp from the caliper. |
- Remove the brake caliper hose bolt from
the brake caliper.
- Remove the 2 metal gaskets from the brake caliper bolt. These gaskets
maybe stuck to the brake caliper and/or the brake hose end.
- Discard the 2 metal gaskets.
- Plug the opening in the front brake hose in order to prevent excessive
brake fluid loss and contamination.
- Remove the brake caliper mounting bolts.
- Remove the brake caliper.
- Remove the brake pads from the brake caliper. Refer to
Front Disc Brake Pads Replacement
.
- Remove the brake caliper mounting bolt sleeves.
- Remove the rubber O-rings.
- Discard the rubber O-rings.
Installation Procedure
- If reusing the brake caliper pin bolts
and retainers, clean the brake caliper pin bolts and retainers using denatured alcohol,
or equivalent.
- Dry the brake caliper pin bolts using non-lubricated, compressed filter
air.
- Lubricate the sleeves and bushings with Delco Silicone Lube, GM P/N 18010909,
or equivalent.
- Install the rubber O-ring bushings to the brake caliper.
- Install the brake caliper mounting bolt
sleeves.
- Install the brake pads to the brake caliper. Refer to
Front Disc Brake Pads Replacement
.
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 brake caliper mounting bolts.
Tighten
Tighten the brake caliper mounting bolts to 51 N·m (38 lb ft).
Notice: Refer to Brake Hose Installation Notice in the Preface section.
Important: When performing the following service procedure, DO NOT reuse the washers,
replace them with new washers.
- Install the front brake hose fitting, the 2 new gaskets and the brake
hose fitting bolt.
Tighten
Tighten the front brake hose bolt to 54 N·m (40 lb ft).
- Fill the brake master cylinder to the proper level. Refer to
Master Cylinder Reservoir Filling
in Hydraulic Brakes.
- Bleed the brake caliper. Refer to
Hydraulic Brake System Bleeding
in Hydraulic Brakes.
- Inspect the brake system for leaks.
- Install the tire and wheel assembly. Refer to
Tire and Wheel Removal and Installation
in Tires and Wheels.
- Lower the vehicle. Refer to
Lifting and Jacking the Vehicle
in General Information.
