Solution

1. Preparation

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

2. Remove Wheel

Loosen the lug nuts on the wheel before lifting the vehicle.
Use a jack to lift the vehicle and place jack stands for support.
Remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Remove the caliper by unscrewing the caliper bolts using a socket set.
Carefully lift the caliper off the rotor; do not let it hang by the brake line.
Remove the old brake pads from the caliper bracket.
Insert new brake pads in the caliper bracket ensuring they are positioned correctly.
Reattach the caliper over the new brake pads and tighten caliper bolts to the manufacturer’s torque specifications (typically around 20-30 ft-lbs).

4. Inspect and Replace Brake Rotors (if necessary)

If rotors are scored or warped, remove the rotor by taking off the retaining screws (if equipped) and sliding it off the hub.
Install new rotors, ensuring they are clean and free from any oil or grease.
Tighten rotor retaining screws if applicable.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque lug nuts to the manufacturer’s specifications (usually around 80-100 ft-lbs).
Pump the brake pedal several times to seat the pads against the rotors before driving.
