Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the negative terminal of the battery for safety.

2. Remove Wheel

Loosen the lug nuts on the wheel where the grinding noise is occurring.
Lift the vehicle using a jack and secure it with jack stands.
Remove the lug nuts and wheel to access the brake components.

3. Inspect and Replace Brake Pads

Locate the brake caliper and remove the caliper bolts using a socket set.
Gently slide the caliper off the rotor; support it using a bungee cord to avoid stressing the brake line.
Remove the old brake pads and inspect for wear; they should be at least 1/4 inch thick.
If worn, install new brake pads following the manufacturer's specifications.

4. Inspect and Resurface or Replace Rotors

Check the rotor surface for grooves, scoring, or warping.
If the rotor is damaged, either resurface it or replace it with a new one.
If resurfacing, ensure the rotor is within the minimum thickness specification.
Clean the rotor surface with brake cleaner before reinstallation.

5. Reassemble Components

Slide the caliper back over the new brake pads and rotor, ensuring it is properly aligned.
Reinstall the caliper bolts and torque them to the manufacturer's specifications (usually around 25-30 ft-lbs).
Reattach the wheel and hand-tighten the lug nuts.

6. Final Checks

Lower the vehicle back to the ground.
Tighten the lug nuts to the specified torque (typically 80-100 ft-lbs).
Reconnect the battery terminal.
