Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Wear safety gloves and goggles for protection.

2. Remove Wheel

Loosen the lug nuts on the wheel where the brake noise is occurring.
Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect Brake Components

Brake Pads: Remove the brake caliper by loosening the caliper bolts. Check the thickness of the brake pads; replace if they are below 3mm.
Brake Rotors: Inspect the rotor surface for grooves, scoring, or warping. Replace if damaged.
Calipers: Check for any signs of corrosion or sticking. Ensure the caliper slides freely.

4. Replace Brake Pads and Rotors (if necessary)

If replacement is needed:
- Remove the old brake pads and rotors.
- Install the new rotor and secure it with the appropriate torque specifications (usually around 100 Nm, but refer to manufacturer specifications).
- Insert new brake pads into the caliper bracket.

5. Reassemble and Test

Reattach the brake caliper and tighten bolts to manufacturer specifications.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and tighten lug nuts to proper torque (typically 110-130 Nm).
Repeat for other wheels if necessary.
