Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the negative battery terminal to ensure safety while working on brakes.

2. Lift and Remove Rear Wheel

Use a jack to lift the rear of the vehicle and secure it with jack stands.
Remove the rear wheel lug nuts using a socket set and take off the wheel.

3. Remove Brake Caliper

Locate the caliper mounting bolts and remove them using a socket wrench.
Carefully slide the caliper off the brake rotor.
Support the caliper using a bungee cord or wire to prevent stress on the brake line.

4. Inspect and Replace Brake Pads

Remove the old brake pads from the caliper bracket.
Inspect the caliper bracket and rotor, clean if necessary.
Install new brake pads into the caliper bracket, ensuring they are properly seated.

5. Inspect and Replace Rotor (if necessary)

If the rotor is scored or damaged, remove it by loosening the retaining screws (if present) and sliding it off the hub.
Install a new rotor, ensuring it is properly aligned and secure.

6. Reassemble Brake Components

Reinstall the caliper over the new pads and rotor.
Tighten the caliper mounting bolts to the manufacturer's specified torque value (usually around 25-35 ft-lbs; check specific specs).

7. Final Checks

Reinstall the wheel and lug nuts. Tighten lug nuts in a star pattern to the specified torque value (usually around 100-120 ft-lbs).
Reconnect the negative battery terminal.
