Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Wear safety goggles and gloves.
Disconnect the negative battery terminal to prevent electrical issues.

2. Remove Wheel

Use a jack to lift the front or rear of the vehicle, depending on which brake is grinding.
Secure the vehicle with jack stands.
Remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Inspect Pads:
- Check the thickness of the brake pads. If they are less than 3mm, replace them.
Remove Old Pads:
- Unbolt the caliper using the appropriate socket.
- Carefully slide the caliper off the rotor.
- Remove the old brake pads from the caliper bracket.
Install New Pads:
- Apply brake grease to the back of the new pads to prevent squeaking.
- Insert the new pads into the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Remove Rotors:
- If the rotors are scored or warped, remove them by unbolting any retaining screws.
Install New Rotors:
- Clean the new rotors with brake cleaner to remove any protective coating.
- Install the new rotors, ensuring they are seated properly.

5. Reassemble Brakes

Reattach the caliper over the new pads and rotor.
Tighten the caliper bolts to the manufacturer’s specified torque (typically 20-30 ft-lbs).
Reinstall the wheel and lug nuts, tightening them in a star pattern to the specified torque (typically 80-100 ft-lbs).

6. Final Checks

Reconnect the negative battery terminal.
Pump the brake pedal several times to ensure the pads seat properly.
Check brake fluid level and add fluid if necessary.
