Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Put on safety goggles and gloves to protect against debris.

2. Remove Wheel

Loosen lug nuts using a socket wrench while the vehicle is on the ground.
Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheel to access the brake assembly.

3. Inspect and Replace Brake Pads

Inspection:
- Examine brake pads for wear; if they are less than 1/8 inch thick, replace them.
- Check for uneven wear patterns or cracks.
Replacement:
- Remove the caliper bolts using a socket wrench.
- Slide the caliper off the rotor and support it with a bungee cord (do not let it hang by the brake line).
- Remove the old brake pads and install new pads, ensuring they are positioned correctly.
- Reinstall the caliper and tighten bolts to the manufacturer's specified torque (usually around 25-35 ft-lbs).

4. Inspect and Replace Brake Rotors (if necessary)

Check for scoring or excessive wear on rotors.
If replacement is needed, remove the caliper and brake pads.
Remove the rotor by unscrewing any retaining screws and sliding it off the hub.
Install the new rotor, ensuring it is seated properly, and reassemble the caliper and brake pads.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle off the jack stands and tighten the lug nuts to the manufacturer's torque specification (usually around 80-100 ft-lbs).
Pump the brake pedal to seat the new pads before driving.
