Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to ensure safety while working on the braking system.

2. Remove the Rear Wheel

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

3. Remove Brake Caliper

Locate the caliper mounting bolts and remove them with the appropriate socket.
Carefully slide the caliper off the brake rotor, supporting it with a bungee cord or rope to avoid stress on the brake line.

4. Inspect and Replace Brake Pads

Remove the old brake pads from the caliper bracket.
Inspect the brake pads for wear; replace if the friction material is less than 3mm thick.
Apply brake lubricant to the backs of the new brake pads and install them into the caliper bracket.

5. Inspect and Replace Brake Rotors (if necessary)

Check the rotor surface for scoring or warping; replace if damaged.
If replacing, remove the old rotor by unscrewing any retaining screws and slide it off the hub.
Install the new rotor and secure it with retaining screws.

6. Reassemble Brake Components

Reattach the caliper over the new brake pads and rotor.
Tighten the caliper mounting bolts to the manufacturer's specified torque (usually around 26-30 ft-lbs).
Reinstall the wheel and tighten lug nuts in a crisscross pattern.
