Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Wear safety goggles and gloves.

2. Lift the Vehicle

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

3. Remove Wheel and Brake Components

Remove the wheel lug nuts using a socket set.
Take off the wheel to access the brake assembly.
Remove the caliper bolts with a socket or wrench to detach the caliper from the rotor.
Carefully hang the caliper using a bungee cord or similar device to avoid stressing the brake line.

4. Inspect and Replace Brake Pads

Remove the old brake pads from the caliper bracket.
Inspect the brake pads for wear indicators; replace if they are worn down to the metal.
Clean the caliper bracket with brake cleaner to remove dust and debris.
Install new brake pads in the caliper bracket, ensuring they are properly aligned.

5. Inspect and Replace Brake Rotors (if necessary)

Check the rotors for grooves or excessive wear.
If damaged, remove the rotor by unscrewing any retaining screws and pulling it off the hub.
Install new brake rotors, ensuring they are clean and free of oil.
Torque any retaining screws to the manufacturer's specifications.

6. Reassemble Brake Components

Reattach the caliper over the new pads and rotor.
Tighten caliper bolts to the manufacturer's torque specification.
Reinstall the wheel and hand-tighten the lug nuts.

7. Lower the Vehicle

Remove the jack stands and carefully lower the vehicle back to the ground.
Fully tighten the lug nuts in a star pattern to ensure even pressure.
