Solution

1. Preparation

Gather tools and parts needed for brake inspection and repair.
Elevate the vehicle using a jack and secure it with jack stands.
Ensure the area is well-ventilated and wear safety glasses.

2. Remove Wheel

Use a lug wrench to loosen and remove the lug nuts on the affected wheel.
Take off the wheel and set it aside.

3. Inspect Brake Components

Brake Pads:
- Check the thickness of the brake pads; replace if less than 3mm.
Brake Rotors:
- Inspect the rotor surface for any abnormalities; replace if warped or excessively worn.
Calipers:
- Ensure calipers move freely; clean and lubricate sliding pins if necessary.

4. Replace Brake Pads and/or Rotors (if needed)

Brake Pad Replacement:
- Remove the caliper by unbolting it from the bracket.
- Replace old brake pads with new ones, ensuring proper orientation.
- Compress the caliper piston using a brake caliper tool to fit over new pads.
Rotor Replacement:
- Remove the rotor by unscrewing any retaining screws and sliding it off the hub.
- Install the new rotor and secure it with retaining screws.

5. Reassemble and Test

Reinstall the caliper over the new brake pads.
Tighten caliper bolts to the manufacturer's specified torque (typically 20-30 ft-lbs).
Reattach the wheel and lug nuts, tightening in a crisscross pattern to manufacturer specifications.
Lower the vehicle and pump the brakes to seat the pads before test driving.
