Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to ensure safety while working on electrical components.

2. Remove Wheel

Using a jack, lift the vehicle and secure it with jack stands.
Remove the wheel lug nuts using a socket wrench and take off the wheel.

3. Inspect and Replace Brake Pads

Inspection:
- Remove the caliper bolts using a socket set and slide the caliper off the rotor.
- Remove the old brake pads from the caliper bracket.
- Measure the thickness of the brake pads; replace if less than 3mm.
Replacement:
- Install new brake pads into the caliper bracket, ensuring they are properly aligned.
- Reattach the caliper over the new pads and tighten caliper bolts to the manufacturer’s torque specifications (typically 20-30 ft-lbs).

4. Inspect and Replace Brake Rotors (if necessary)

If rotors are scored or warped, remove the rotor by unscrewing the retaining screws (if applicable) and sliding it off the hub.
Install new rotors, ensuring they are clean and free of grease.
Torque the rotor retaining screws to the manufacturer’s specifications.

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 (typically 80-100 ft-lbs).
Reconnect the battery.
Test drive the vehicle at low speeds to ensure the grinding noise is eliminated and braking performance is restored.
