Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, brake cleaner, gloves, safety goggles.
Ensure the vehicle is parked on a level surface and the engine is off.
Wear safety goggles and gloves for protection.

2. Remove Wheel

Loosen the lug nuts slightly while the vehicle is still on the ground.
Use the jack to lift the vehicle and securely place it on jack stands.
Completely remove the lug nuts and take off the wheel.

3. Inspect Brake Components

Brake Pads:
- Remove the caliper mounting bolts using a socket set.
- Carefully slide the caliper off the rotor and support it with a bungee cord (do not let it hang by the brake line).
- Inspect the brake pads for wear; replace if less than 1/4 inch thick or if unevenly worn.
Brake Rotors:
- Check the rotors for scoring, grooves, or warping; replace if necessary.
- If the rotors are within specs, clean them with brake cleaner to remove dust and debris.

4. Replace Brake Pads and Rotors (if necessary)

Brake Pads:
- If replacement is needed, remove the old pads and install new ones in the same orientation.
- Ensure the anti-rattle clips are in place.
Brake Rotors:
- If replacing rotors, remove the old rotor and install the new rotor, ensuring it is seated properly against the hub.

5. Reassemble and Test

Reattach the caliper over the new pads and tighten the caliper mounting bolts to the manufacturer's torque specifications.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer's specifications.
