Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to avoid any electrical issues during the repair.

2. Remove Wheel

Tools Required: Socket set, lug wrench
Loosen the lug nuts on the wheel with the grinding issue.
Lift the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Tools Required: Brake pad spreader, torque wrench
Remove the caliper bolts using the appropriate socket.
Carefully slide the caliper off the rotor and support it with a bungee cord (do not let it hang by the brake line).
Remove the old brake pads from the caliper bracket.
Inspect the brake pads for thickness; replace if they’re below manufacturer specifications (typically 3mm).
Install new brake pads into the caliper bracket, ensuring they are properly seated.

4. Inspect and Replace Brake Rotors (if necessary)

Tools Required: Rotor puller (if applicable), torque wrench
Check the rotors for any scoring or warping; replace if damaged.
If replacement is needed, remove the rotor by taking off the retaining screws (if applicable) and sliding it off the hub.
Install the new rotor, ensuring it is aligned properly and secure it if necessary.

5. Reassemble Brake Components

Reinstall the caliper over the new brake pads and rotor.
Torque the caliper bolts to the manufacturer's specifications (typically around 20-30 ft-lbs, but refer to specific service manual).
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Final Checks

Lower the vehicle from the jack stands.
Tighten the lug nuts in a star pattern to the manufacturer’s torque specification (typically around 85-100 ft-lbs).
Reconnect the battery.
