Solution

1. Preparation

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

2. Remove Wheel

Use a jack to lift the vehicle and securely place it on jack stands.
Remove the lug nuts using a socket set and take off the wheel.

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Remove the caliper bolts using a socket set.
- Carefully lift the caliper off the rotor and support it using a bungee cord or similar device to avoid strain on the brake line.
- Check the thickness of the brake pads; if they are worn below the manufacturer’s specifications (usually around 3mm), replace them.
Replace Brake Pads:
- Remove the old brake pads from the caliper bracket.
- Clean the caliper bracket and apply brake grease to the contact points.
- Install new brake pads, ensuring they are secured properly.

4. Inspect and Replace Brake Rotors (if necessary)

Inspect Brake Rotors:
- Check for any scoring, warping, or uneven surfaces.
Replace Rotors:
- If replacement is necessary, remove the rotor by unscrewing the retaining screws (if applicable) and sliding it off the hub.
- Install the new rotor, ensuring it sits flush against the hub; torque any retaining screws to manufacturer specifications.

5. Reassemble Components

Reposition the caliper over the new brake pads and rotor.
Reinstall and tighten caliper bolts to the manufacturer's specified torque.
Reattach the wheel and hand-tighten the lug nuts.

6. Final Checks

Lower the vehicle back to the ground and tighten the lug nuts to the proper torque specification.
Reconnect the battery.
