Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Lift the vehicle using a jack and secure with jack stands.

2. Remove the Wheel

Using a lug wrench, loosen and remove the lug nuts on the wheel associated with the grinding brakes.
Remove the wheel and set it aside.

3. Inspect Brake Components

Brake Pads:
- Remove the caliper bolts using a socket set.
- Slide the caliper off and suspend it using a wire to avoid stress on the brake line.
- Inspect brake pads for thickness; replace if less than 1/8 inch.
Brake Rotors:
- Inspect rotors for scoring or warping. Use a caliper gauge for thickness measurement.
- If damaged, replace the rotors.

4. Replace Brake Pads and Rotors (if necessary)

Brake Pad Replacement:
- Remove old brake pads from the caliper bracket.
- Apply brake grease to the backing of new pads.
- Insert new brake pads into the caliper bracket.
Rotor Replacement:
- Remove the old rotor; clean the hub surface.
- Install the new rotor, ensuring it is seated properly.

5. Reassemble Components

Reattach the caliper over the new pads and rotor.
Torque the caliper bolts to the manufacturer’s specifications (typically around 20-25 ft-lbs).
Reinstall the wheel and tighten lug nuts in a star pattern to ensure even pressure.

6. Final Checks

Lower the vehicle back to the ground.
Pump the brake pedal a few times to seat the brake pads.
Check brake fluid level and top off if necessary.
