Solution

1. Preparation

Gather tools and parts needed for the repair.
Required tools: socket set, torque wrench, brake cleaner, C-clamp or brake caliper tool, jack and jack stands, wheel chocks.
Safety warnings: Ensure the vehicle is on a flat surface and the parking brake is engaged.

2. Raise the Vehicle

Loosen the lug nuts on the rear wheels slightly while the vehicle is on the ground.
Use a jack to lift the rear of the vehicle and secure it with jack stands.
Remove the rear wheels by completely unscrewing the lug nuts.

3. Remove Brake Components

Locate the brake caliper assembly on the rear brakes.
Use the socket set to remove the caliper bolts and gently slide the caliper off the rotor.
Secure the caliper away from the rotor using a bungee cord or similar method to avoid stress on the brake line.
Remove the old brake pads from the caliper bracket.

4. Inspect and Replace Components

Check the brake rotor for wear; if needed, replace the rotor. If it is in acceptable condition, clean it with brake cleaner.
If replacing the pads, install new brake pads into the caliper bracket ensuring they are positioned correctly.
Compress the caliper piston using a C-clamp or brake caliper tool to allow for the new pads' thickness.

5. Reassemble the Brake System

Reattach the brake caliper over the new brake pads and rotor, aligning it properly.
Torque the caliper bolts to the manufacturer's specifications (usually around 25-30 ft-lbs).
Reinstall the rear wheels and torque the lug nuts in a star pattern to the specified torque (typically around 76 ft-lbs).

6. Final Steps

Lower the vehicle from the jack stands and remove the jack.
Pump the brake pedal several times to seat the brake pads against the rotor.
Check the brake fluid level and top off if necessary.
