Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to prevent any electrical issues during repair.

2. Remove Wheels

Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheel lug nuts using a socket set and take off the wheels.

3. Inspect and Replace Brake Pads

Inspect: Remove the brake caliper by unbolting it from the rotor (typically two bolts). Carefully hang the caliper using a bungee cord to avoid stress on the brake line.
Replace: If the pads are worn down to the metal or have uneven wear, replace them. Remove the old pads and install new brake pads. Ensure they are fitted properly into the caliper bracket.

4. Inspect and Replace Rotors (if necessary)

Check the brake rotors for any grooves or scoring. If they are damaged or below the minimum thickness specification, replace them.
- Remove: Unbolt the rotor from the hub (may require a hammer to gently tap it off if rusted).
- Install: Place the new rotor on the hub and secure it with bolts to the manufacturer's torque specifications.

5. Reassemble and Test

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