Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety gloves and goggles.

2. Remove Wheel

Use a jack to lift the car and secure it with jack stands.
Remove the lug nuts with a socket wrench and take off the wheel.

3. Inspect Brake Components

Brake Pads:
- Remove the caliper bolts using a socket wrench.
- Slide the caliper off the rotor and inspect the pads for thickness. If less than 3mm, replace them.
Brake Rotors:
- Check the rotors for any grooves or irregularities. If they are scored or warped, they should be replaced or resurfaced.
Calipers:
- Inspect calipers for any signs of leakage or sticking. If damaged, replace the caliper.
Brake Hardware:
- Check all associated hardware for wear. Replace any rusted or damaged clips.

4. Replace Brake Pads and Rotors (if necessary)

Brake Pads:
- Install new brake pads, ensuring they are oriented correctly.
- Apply brake grease to the backing of the pads to prevent noise.
Rotors:
- If replacing, install new rotors, ensuring they are torqued to the manufacturer's specifications (typically around 80-100 ft-lbs).

5. Reassemble Components

Reattach the caliper over the new pads and rotor.
Torque caliper bolts to the manufacturer’s specifications.
Reinstall the wheel and lug nuts, tightening them in a crisscross pattern.

6. Final Checks

Lower the vehicle and pump the brake pedal to restore pressure.
Conduct a visual inspection to ensure everything is secure.
