Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the engine is off.
Wear safety glasses and gloves for protection.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts.
Lift the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect Brake Components

Brake Pads:
- Remove the caliper by unscrewing the caliper bolts with a socket set.
- Slide the caliper off the rotor without disconnecting the brake line.
- Inspect the brake pads for thickness; replace them if they are less than 3mm thick.
Brake Rotors:
- Check for grooves or scoring on the rotor surface.
- Measure rotor thickness using a caliper; replace if below manufacturer specifications.

4. Replace Brake Pads (if necessary)

Remove the old brake pads from the caliper bracket.
Lubricate the backing of the new pads with high-temperature brake grease.
Install the new brake pads into the caliper bracket.

5. Reassemble Components

Reattach the caliper over the new pads and secure it with bolts; torque to the manufacturer’s specifications (typically around 25-30 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower the Vehicle

Remove the jack stands and lower the vehicle to the ground.
Tighten the lug nuts in a star pattern to the manufacturer’s torque specifications (typically around 76 ft-lbs).
