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 negative battery terminal to prevent accidental electrical issues.

2. Remove the Wheel

Use a lug wrench to loosen the lug nuts on the wheel.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel to access the brake assembly.

3. Inspect and Replace Brake Pads

Inspection: Check the thickness of the brake pads. If they are worn down (less than 3mm), they need replacement.
Replacement:
- Use a C-clamp or brake caliper tool to compress the caliper piston.
- Remove the caliper bolts with a socket set and slide the caliper off the rotor.
- Remove the old brake pads from the caliper bracket and replace them with new ones.
- Reinstall the caliper over the new pads and tighten the caliper bolts to the manufacturer’s specified torque (usually around 20-30 ft-lbs).

4. Check and Replace Brake Rotors (if necessary)

If the rotors are scored or warped, they need to be replaced.
Remove the caliper bracket by unscrewing the bolts.
Slide the rotor off the hub. If it's stuck, gently tap it with a rubber mallet.
Install the new rotor, ensuring it is properly seated.
Reinstall the caliper bracket and tighten to the specified torque.

5. Reassemble and Reinstall Wheel

Place the wheel back on the hub and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and tighten the lug nuts in a crisscross pattern to the specified torque (typically 80-100 ft-lbs).

6. Test Brakes

Reconnect the negative battery terminal.
Pump the brake pedal a few times to ensure the caliper piston is seated properly.
Test drive the vehicle at low speeds to ensure brakes function correctly without noise.
