Solution

1. Preparation

Tools Required: Socket set, torque wrench, brake cleaner, C-clamp or brake caliper tool, jack stands, and wheel chocks.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to prevent any electrical issues during the repair.

2. Lift 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 fully unscrewing the lug nuts.

3. Remove Brake Caliper

Locate the caliper mounting bolts on the rear brake caliper.
Use the socket set to remove the caliper mounting bolts.
Carefully slide the caliper off the brake rotor. Do not let it hang by the brake line; use a bungee cord or similar to secure it in place.

4. Remove Old Brake Pads

Once the caliper is removed, take note of the positioning of the old brake pads.
Slide the old brake pads out from the caliper bracket.
Inspect the caliper bracket for any damage or wear.

5. Install New Brake Pads

Apply a thin layer of brake grease to the back of the new brake pads to prevent noise.
Insert the new brake pads into the caliper bracket in the same orientation as the old pads.
Ensure they are seated properly and securely.

6. Reinstall Brake Caliper

Use the C-clamp to compress the caliper piston back into the caliper housing, allowing enough space for the new pads.
Align the caliper over the new brake pads and slide it back into position.
Reinstall the caliper mounting bolts and tighten them to the manufacturer's specified torque.

7. Reassemble Wheel

Reinstall the rear wheel and hand-tighten the lug nuts.
Lower the vehicle back to the ground and then tighten the lug nuts to the specified torque in a criss-cross pattern.
