Removal Procedure
WARNING: This page is about a different car, the 2018 Chevrolet Trax and 2018 Buick Encore. However, it is still accessible from the selected car via links, so may be relevant.
WARNING:
Refer to Brake Dust Warning .
NOTE:
Always replace disc brake pads in axle sets.
- 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 before proceeding.
- If the brake fluid level is higher than midway between the maximum-full point and the minimum allowable level, remove brake fluid to the midway point before proceeding.
- Raise and support the vehicle. Lifting and Jacking the Vehicle
- Remove the tire and wheel assembly. Tire and Wheel Removal and Installation
- Place a large C-clamp over the brake caliper body and against the outer brake pad.
- Using the C-clamp, compress the brake caliper piston fully into the brake caliper bore.
- NOTE:
- DO NOT use any air tools to remove or install the guide pin bolts. Use hand tools ONLY.
- Install an open end wrench to hold the caliper guide pin in line with the brake caliper while removing or installing the caliper guide pin bolt. DO NOT allow the open end wrench to come in contact with the brake caliper. Allowing the open end wrench to come in contact with the brake caliper will cause a pulsation when the brakes are applied.
Using a backup wrench to hold the brake caliper guide pin stationary, remove the lower brake caliper guide pin bolt (1).
- Rotate the brake caliper upward and support with heavy mechanics wire.
- NOTE:
Note the location of the brake pad wear sensor for correct installation.
Remove the inner disc brake pad (1).
- Remove the outer disc brake pad (2).
Remove the upper and lower disc brake pad springs (1).
- If installing new brake pads, discard the disc brake pad springs.
CAUTION:
Support the brake caliper with heavy mechanic wire, or equivalent, whenever it is separated from its mount and the hydraulic flexible brake hose is still connected. Failure to support the caliper in this manner will cause the flexible brake hose to bear the weight of the caliper, which may cause damage to the brake hose and in turn may cause a brake fluid leak.
