Solution

1. Preparation

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

2. Remove the Wheel

Sub-steps:
1. Loosen the lug nuts on the wheel.
2. Jack up the vehicle and secure it with jack stands.
3. Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the caliper bolts using a socket wrench.
2. Carefully slide the caliper off the rotor without stretching the brake line.
3. Remove the old brake pads from the caliper bracket.
4. Compare the thickness of the new pads to the old pads to ensure they meet manufacturer specifications.
5. Install the new brake pads into the caliper bracket.
6. Reinstall the caliper over the new pads and tighten the caliper bolts to the manufacturer’s torque specifications.

4. Inspect and Replace Rotors (if necessary)

Sub-steps:
1. If the rotors are worn or damaged, remove them from the hub by unscrewing the retaining screws.
2. Clean the hub surface for proper rotor seating.
3. Install new rotors, ensuring they are aligned properly.
4. Secure with screws and ensure they are tightened to specification.

5. Reassemble and Test

Sub-steps:
1. Reinstall the wheel and hand-tighten the lug nuts.
2. Lower the vehicle and tighten the lug nuts to the manufacturer’s torque specifications.
3. Pump the brake pedal several times to ensure the brake pads are seated correctly.
4. Test drive the vehicle to ensure the grinding noise is resolved.
