Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Use wheel chocks to prevent movement.

2. Remove Wheel

Use a jack to lift the vehicle and place it securely on jack stands.
Remove the wheel using a lug wrench.

3. Inspect and Replace Brake Pads

Remove the brake caliper by loosening the caliper bolts with a socket set.
Carefully slide the caliper off the rotor and support it using a bungee cord (do not allow it to hang by the brake line).
Remove old brake pads from the caliper bracket.
Inspect the bracket for any debris or damage.
Install new brake pads into the caliper bracket, ensuring they are seated properly.

4. Inspect and Replace Brake Rotors

If the rotors are scored or warped, remove them from the hub by unscrewing the retaining screws if equipped.
Clean the hub surface with a wire brush to ensure proper rotor seating.
Install new rotors, ensuring they are properly aligned and secured.

5. Reassemble and Test

Reinstall the brake caliper over the new pads and rotor.
Tighten the caliper bolts to the manufacturer’s specified torque (usually around 25-30 ft-lbs).
Reinstall the wheel and lower the vehicle to the ground.
Tighten the lug nuts in a crisscross pattern to the manufacturer’s specified torque (usually around 76-80 ft-lbs).
