Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat, stable surface.
Wear safety goggles and gloves.

2. Raise the Vehicle

Use a jack to lift the front or rear of the vehicle depending on which brakes are grinding.
Secure the vehicle with jack stands for safety.

3. Remove the Wheel

Using a socket set, loosen and remove the lug nuts.
Take off the wheel to access the brake assembly.

4. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Check the thickness of the brake pads; replace if they are below the minimum thickness (usually 3mm).
Remove Old Brake Pads:
- Use a socket wrench to remove the caliper bolts.
- Slide the caliper off the rotor and hang it using a bungee cord to avoid stressing the brake line.
- Remove the old brake pads from the caliper bracket.
Install New Brake Pads:
- Apply brake lubricant to the backing of the new pads.
- Position the new pads in the caliper bracket.

5. Check and Replace Brake Rotors (if necessary)

Inspect Rotors:
- Check for deep grooves or scoring.
Remove Rotors:
- If damaged, remove the caliper bracket and unscrew the rotor from the hub.
Install New Rotors:
- Position the new rotor on the hub and secure it with screws.

6. Reassemble the Brake Assembly

Reattach the caliper over the new brake pads and rotor.
Tighten the caliper bolts to the manufacturer's specified torque (typically 20-25 ft-lbs).

7. Reinstall the Wheel

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle and then fully tighten the lug nuts in a crisscross pattern to the specified torque (usually 80-100 ft-lbs).

8. Final Checks

Pump the brake pedal to ensure the pads seat correctly.
Check brake fluid level and add if necessary.
