Solution

1. Preparation

Tools Required:
- Jack and jack stands
- Lug wrench
- Socket set
- Torque wrench
- Brake cleaner
- Wire brush
Safety Warnings:
- Ensure the vehicle is on a flat surface and securely lifted.
- Wear safety goggles and gloves.

2. Remove the Wheel

Loosen the lug nuts with the lug wrench while the vehicle is on the ground.
Lift the vehicle using the jack and secure it on jack stands.
Completely remove the lug nuts and take off the wheel to access the brake components.

3. Inspect Brake Components

Brake Pads:
- Remove the caliper bolts using the socket set.
- Carefully slide the caliper off the rotor.
- Inspect the brake pads for wear. Replace if the pad thickness is less than 3mm.
Brake Rotors:
- Check the surface of the rotors for grooves or scoring.
- Use a micrometer to measure rotor thickness. Replace if below specifications.
Calipers:
- Inspect caliper slides for movement. Clean and lubricate if necessary.
- Ensure the caliper piston moves freely.

4. Replace Worn Components

Brake Pads:
- If pads are worn, install new brake pads. Ensure they are oriented correctly.
Brake Rotors:
- If rotors are damaged, replace them with new ones. Torque the rotor retaining screws to manufacturer specifications.
Calipers:
- If calipers are binding, consider rebuilding or replacing them.

5. Reassemble and Test

Reattach the caliper to the rotor and tighten the caliper bolts to the specified torque.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and fully tighten the lug nuts in a crisscross pattern to the specified torque.
