Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical issues.

2. Raise the Vehicle

Use a hydraulic jack to lift the front or rear of the vehicle, depending on where the grinding noise is coming from.
Secure the vehicle with jack stands to ensure safety.

3. Remove Wheel

Use a lug wrench to remove the lug nuts and take off the wheel.
Store the lug nuts in a safe place.

4. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket wrench.
Carefully slide the caliper off the rotor; support it with a bungee cord to avoid straining the brake line.
Inspect the brake pads; if they are worn down to the backing plate, replace them.
Use a brake pad spreader tool to compress the caliper piston back into the caliper housing.
Install new brake pads, ensuring they are properly aligned and secured.

5. Inspect and Replace Brake Rotors

If rotors are damaged or worn beyond specifications, remove them by unscrewing the rotor retaining screws (if applicable) and sliding them off the hub.
Clean the hub surface with brake cleaner before installing the new rotor.
Install new rotors and secure them with screws if necessary.

6. Reassemble Brake Components

Reattach the brake caliper over the new pads and rotor; tighten the caliper bolts to the manufacturer’s specified torque (usually around 20-25 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts before lowering the vehicle.

7. Lower the Vehicle

Carefully remove the jack stands and lower the vehicle back to the ground.
Tighten the lug nuts to the correct torque specification (usually around 80-100 ft-lbs) in a crisscross pattern.
