Solution

1. Preparation

Gather tools and safety equipment (gloves, safety glasses).
Park the vehicle on a level surface and set the parking brake.
Loosen lug nuts on the wheels before raising the vehicle.

2. Raise Vehicle

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

3. Remove Wheel

Remove the lug nuts completely and take off the wheel to access the brake components.
Store lug nuts in a safe place to avoid losing them.

4. Inspect and Replace Brake Pads

Remove the caliper by unscrewing the caliper bolts using a socket set.
Carefully slide the caliper off the brake rotor, supporting it to prevent strain on the brake line.
Remove the old brake pads from the caliper bracket.
Inspect the brake pads for thickness; replace if they are worn down to the indicator or below.
Install new brake pads, ensuring they are properly seated in the caliper bracket.

5. Inspect and Resurface or Replace Rotors

Check the brake rotors for any significant grooves or warping.
If the rotors are scored, they may need to be resurfaced or replaced.
To replace, remove the rotor by unscrewing the retaining screws (if applicable) and sliding it off the hub.
Install new or resurfaced rotors, ensuring they are clean and free of debris.

6. Reassemble Brake Components

Reattach the caliper over the new brake pads and rotor.
Tighten caliper bolts to the manufacturer’s specified torque (usually around 20-30 lb-ft, check specifications).
Reinstall the wheel and hand-tighten the lug nuts.

7. Lower Vehicle

Carefully lower the vehicle back to the ground and fully tighten the lug nuts in a crisscross pattern to the specified torque (typically 80-100 lb-ft).

8. Test the Brakes

Pump the brake pedal several times to ensure proper brake engagement.
Check for any abnormal noises before taking the vehicle for a test drive.
