Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface, engage the parking brake, and place wheel chocks behind the rear tires.
Disconnect the battery to ensure safety while working on the braking system.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts on the affected wheel.
Raise the vehicle using a jack and secure it with jack stands.
Fully remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Inspect Brake Pads: Check for uneven wear; if replacement is needed, proceed to the next step.
Remove Caliper: Use a socket set to remove the caliper bolts. Support the caliper with a bungee cord or hang it to avoid stress on the brake line.
Remove Old Brake Pads: Slide out the old brake pads from the caliper bracket.
Install New Brake Pads: Insert the new brake pads into the caliper bracket; ensure they are seated properly.

4. Inspect and Replace Brake Rotors (if necessary)

Remove Caliper Bracket: If the rotors are worn, remove the caliper bracket by unscrewing its bolts.
Remove Rotors: Slide off the old rotors. Clean the hub surface with a wire brush if needed.
Install New Rotors: Place new rotors onto the hub, ensuring they are flush against the mounting surface. Secure with the appropriate hardware.

5. Reassemble Braking System

Reattach the caliper bracket and torque to manufacturer specifications (usually around 30-40 Nm).
Reinstall the caliper over the new brake pads and torque the caliper bolts to specifications (typically 25-30 Nm).
Reattach the wheel and hand-tighten the lug nuts.

6. Reconnect Battery and Test

Reconnect the battery.
Lower the vehicle and remove wheel chocks.
Pump the brake pedal to seat the pads before driving.
