Solution

1. Preparation

Gather tools and parts required.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Tools Required: Jack and jack stands, lug wrench, socket set, torque wrench, brake cleaner, safety glasses, gloves.
Parts Required: New brake pads, brake rotors (if necessary), brake lubricant.

2. Raise the Vehicle

Loosen the lug nuts on the wheel where the grinding noise is observed.
Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheel.

3. Remove Brake Components

Remove the caliper bolts using the appropriate socket.
Carefully lift the caliper off the brake rotor; support it to avoid strain on the brake line.
Remove the old brake pads from the caliper bracket.

4. Inspect and Replace

Check the brake rotor for wear. If it shows signs of scoring or warping, replace it.
Clean the rotor surface with brake cleaner.
Install new brake pads in the caliper bracket, applying brake lubricant to the backing plates to reduce noise.
If necessary, install new rotors according to manufacturer specifications.

5. Reassemble Braking System

Reattach the caliper over the new pads and rotor.
Tighten the caliper bolts to the manufacturer’s torque specifications.
Reinstall the wheel and tighten the lug nuts in a crisscross pattern.

6. Lower the Vehicle

Remove the jack stands and lower the vehicle back to the ground.
Tighten the lug nuts to the specified torque while the vehicle is on the ground.
