Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is on a flat surface and engage the parking brake.
Use jack stands to secure the vehicle after lifting it with a jack.

2. Remove Wheel

Use a lug wrench to loosen and remove the lug nuts.
Remove the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Remove the caliper by unscrewing the caliper bolts.
Slide the caliper off the rotor and secure it with a bungee cord to avoid straining the brake line.
Remove the old brake pads from the caliper bracket.
Insert new brake pads into the caliper bracket (ensure they are the correct fit).
Reinstall the caliper over the new pads and secure it with the caliper bolts at the specified torque (typically around 20-25 ft-lbs, but refer to the service manual for exact values).

4. Inspect and Replace Brake Rotors (if necessary)

If rotors are warped, remove them by unscrewing the retaining screws and sliding them off the hub.
Clean the hub surface with a wire brush.
Install new rotors, ensuring they are properly seated.
Torque the retaining screws as specified in the service manual.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and fully tighten the lug nuts to the manufacturer’s specified torque.
Pump the brake pedal a few times to ensure the pads seat correctly and restore brake pressure.
