Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, socket set, torque wrench, brake cleaner, C-clamp or brake tool, safety glasses, gloves.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Wear safety glasses and gloves for protection.

2. Raise the Vehicle

Loosen the lug nuts on the front or rear wheels (where grinding is occurring) with a lug wrench.
Use a jack to lift the vehicle and support it with jack stands.
Remove the lug nuts and take off the wheel.

3. Inspect and Remove Brake Components

Inspect Brake Pads:
- Check the thickness of the brake pads. If they are less than 3 mm, they should be replaced.
Remove Brake Caliper:
- Use a socket set to remove the bolts securing the brake caliper.
- Carefully slide the caliper off the rotor and support it using a bungee cord or similar tool to avoid straining the brake line.

4. Replace Brake Pads and Rotors

Replace Brake Pads:
- Remove the old brake pads from the caliper bracket.
- Clean the caliper bracket and apply brake grease to the contact points of the new pads.
- Install the new brake pads, ensuring they are properly seated.
Replace Rotors (if needed):
- If rotors are damaged, remove the caliper bracket using the socket set.
- Slide off the old rotor and replace it with a new one.
- Ensure the new rotor is clean and free from oil or grease.

5. Reassemble Components

Reattach the caliper over the new pads and secure it with the caliper bolts.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the manufacturer’s specifications (typically around 80-100 ft-lbs, verify with your manual).

6. Final Checks

Pump the brake pedal several times to ensure proper pad seating and restore brake pressure.
Inspect brake fluid levels and top off if necessary.
