Solution

1. Preparation

Gather tools and safety equipment.
Tools Required: Jack and jack stands, lug wrench, socket set, torque wrench, micrometer, brake pad spreader, brake cleaner.
Safety Warnings: Always wear safety goggles and gloves. Ensure the vehicle is on a flat surface and securely supported with jack stands.

2. Remove the Wheel

Use a lug wrench to loosen the lug nuts on the affected wheel.
Jack up the vehicle and secure it with jack stands.
Completely remove the lug nuts and the wheel.

3. Inspect Brake Components

Check the brake pads for wear; replace if they are less than 3mm thick or if there are signs of damage.
Inspect the brake rotors for scoring, warping, or cracks; replace if necessary.

4. Replace Brake Pads and/or Rotors

Brake Pad Replacement:
- Use a brake pad spreader to compress the caliper piston.
- Remove the caliper bolts with a socket set, and carefully lift off the caliper.
- Remove the old brake pads from the caliper bracket.
- Install new brake pads into the bracket, ensuring proper orientation.
- Reattach the caliper over the new pads and secure with bolts. Torque to manufacturer specifications.
Rotor Replacement (if necessary):
- Remove the caliper bracket if the rotor is stuck.
- Remove the rotor from the hub and replace it with a new rotor.
- Reinstall the caliper bracket if it was removed.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer's specifications.
Pump the brake pedal to ensure proper pad seating and brake function.
Test drive the vehicle at low speeds to ensure noise is resolved.
