Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Wear safety goggles and gloves.

2. Remove Wheel

Loosen lug nuts on the affected wheel while the vehicle is on the ground.
Jack up the vehicle safely using a jack and secure with jack stands.
Completely remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Components

Inspect Brake Pads:
- Remove the caliper bolts using a socket set.
- Slide the caliper off the rotor and secure it with a bungee cord (do not let it hang by the brake line).
- Check the brake pads’ thickness; replace if less than 1/4 inch.
Inspect Brake Rotors:
- Check for grooves or scoring on the rotors.
- If damaged, remove the rotor by unscrewing the retaining screws (if applicable) and slide it off.
- Replace with new rotors if necessary.
Install New Brake Pads:
- Apply brake grease to the contact points of the new pads.
- Insert new brake pads into the caliper bracket.

4. Reassemble and Test

Reattach the caliper over the new pads and torque caliper bolts to manufacturer specifications (typically 20-30 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the specified value (typically 75-85 ft-lbs).
Pump the brake pedal to seat the new pads before driving.
