Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface with the parking brake engaged.
Wear safety gear such as gloves and goggles.

2. Lift 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 Wheel Assembly

Use a socket set to remove the lug nuts and take off the wheel.
Store the lug nuts in a safe location to prevent loss.

4. Inspect and Replace Brake Pads

Remove Brake Caliper:
- Use a socket to remove the caliper bolts.
- Carefully slide the caliper off the brake rotor and suspend it using a bungee cord or similar to avoid stress on the brake line.
Remove Old Brake Pads:
- Slide the old brake pads out of the caliper bracket.
Install New Brake Pads:
- Apply a small amount of brake grease to the back of the new pads (avoid the friction surface).
- Insert the new pads into the caliper bracket.

5. Inspect and Replace Brake Rotors (if necessary)

Remove Brake Rotor:
- If the rotor is damaged, remove the retaining screws (if present) and slide the rotor off the hub.
Install New Brake Rotor:
- Clean the hub surface and slide on the new rotor.
- Secure it with retaining screws.

6. Reassemble Brake Components

Reinstall Brake Caliper:
- Slide the caliper back over the new brake pads and rotor.
- Tighten the caliper bolts to the manufacturer's torque specifications (typically around 25-30 ft-lbs).
Reattach Wheel:
- Place the wheel back onto the hub.
- Hand-tighten the lug nuts, then lower the vehicle and use a torque wrench to tighten to the manufacturer's specifications (typically around 76-83 ft-lbs).
