Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and engage the parking brake.
Disconnect the battery to prevent any electrical issues during the repair.

2. Remove the Wheel

Use a lug wrench to loosen the lug nuts slightly before raising the vehicle.
Lift the rear of the vehicle using a jack and secure it with jack stands.
Fully remove the lug nuts and take off the rear wheel.

3. Inspect and Replace Brake Pads

Remove the brake caliper by loosening the caliper bolts with a socket wrench.
Carefully slide the caliper off the brake pads and hang it using a bungee cord or wire to avoid stress on the brake line.
Remove the old brake pads from the caliper bracket.
Inspect the caliper for damage or sticking; replace if necessary.
Install new brake pads, ensuring they are properly aligned with the caliper bracket.

4. Check and Replace Brake Rotors (if necessary)

Inspect the rotor surface for scoring or excessive wear.
If the rotors are damaged or below the minimum thickness specification, remove the retaining screws and pull off the rotor.
Replace with new rotors if needed, ensuring they are clean and free of any oil or debris before installation.

5. Reassemble and Reinstall Components

Reattach the brake caliper over the new pads and tighten the caliper bolts to the manufacturer's torque specification.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle back to the ground and fully tighten the lug nuts in a star pattern to the specified torque.
