Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Wear safety goggles and gloves.

2. Remove Wheel

Loosen lug nuts while the vehicle is on the ground.
Raise the vehicle using a jack and support it with jack stands.
Remove the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket set.
Carefully slide the caliper off the rotor; do not let it hang by the brake line.
Remove the old brake pads from the caliper bracket.
Inspect the caliper for damage or sticking.
Install new brake pads, ensuring they are oriented correctly.
Apply brake grease to the back of the pads and the caliper hardware.

4. Inspect and Resurface or Replace Rotors

Check rotors for warping or scoring.
If necessary, either resurface the rotors or replace them with new ones.
Ensure rotor surfaces are clean and free of debris before reinstallation.

5. Reassemble Components

Reinstall the caliper over the new brake pads.
Torque caliper bolts to the manufacturer's specifications (usually around 25-35 ft-lbs).
Reinstall the wheel and torque lug nuts in a star pattern to the specified torque (usually around 80-100 ft-lbs).

6. Final Checks

Lower the vehicle and remove wheel chocks.
Pump the brake pedal to ensure proper seating of the pads.
Test the brakes at low speed to ensure noise is resolved.
