Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Wear safety goggles and gloves for protection.

2. Remove Wheel

Sub-steps:
- Loosen the lug nuts on the wheel with the impact wrench or lug wrench.
- Raise the vehicle using a jack and secure it with jack stands.
- Remove the lug nuts completely and take off the wheel.
Tools Required: Impact wrench or lug wrench, jack, jack stands.

3. Inspect and Replace Brake Pads

Sub-steps:
- Remove the caliper bolts using a socket set.
- Carefully lift the caliper off the rotor and suspend it with a bungee cord (do not let it hang by the brake line).
- Inspect the brake pads for wear; if they are worn down to the metal, replace them.
- Remove the old brake pads from the caliper bracket.
- Apply brake grease to the back of the new pads and install them in the caliper bracket.
Tools Required: Socket set, bungee cord, brake grease.

4. Inspect and Replace Brake Rotors (if needed)

Sub-steps:
- If rotors are scored or warped, remove the rotor by unscrewing the retaining screws (if applicable) and sliding it off the hub.
- Clean the hub surface and install the new rotor, ensuring it is seated properly.
Tools Required: Screwdriver, clean rags.

5. Reassemble Components

Sub-steps:
- Reposition the caliper over the new brake pads and secure it by tightening the caliper bolts to the manufacturer’s torque specifications.
- Reinstall the wheel and tighten the lug nuts by hand.
- Lower the vehicle and then tighten the lug nuts to the proper torque specification in a crisscross pattern.
Tools Required: Torque wrench.
