Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, brake cleaner, torque wrench, socket set, safety glasses, gloves.
Lift the vehicle using a jack and secure it on jack stands. Ensure the vehicle is on a flat surface and the parking brake is engaged.

2. Remove Wheel

Loosen the lug nuts on the wheel where the grinding noise originates.
Remove the lug nuts and take off the wheel to access the braking components.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket wrench.
Carefully lift the caliper off the rotor and support it (do not hang it from the brake line).
Inspect the brake pads for wear. If the pads are worn down to the backing plate or show uneven wear, replace them.
Use brake cleaner to clean the caliper and rotor surfaces.
Install new brake pads ensuring they are properly seated in the caliper bracket.

4. Inspect and Resurface/Replace Rotors

Check the rotors for grooves or warping using a straightedge. If they are scored or warped beyond the manufacturer's specifications, they should be resurfaced or replaced.
If resurfacing, ensure the rotor is within the acceptable thickness limits.
Clean the rotor with brake cleaner before reinstallation.

5. Reassemble and Torque

Reposition the caliper over the new brake pads and secure it with bolts.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer’s specifications (typically between 75-100 ft-lbs; check specific values for your model).

6. Final Checks

Recheck brake fluid level in the master cylinder and top off if necessary.
Test the brakes by pumping the pedal a few times before driving.
