Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and engage the parking brake.
Wear safety gloves and goggles.

2. Raise the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on which brakes are making the noise.
Secure with jack stands for safety.

3. Remove Wheel

Use a lug wrench to loosen and remove the wheel to access the brake assembly.
Store lug nuts in a safe place for reinstallation.

4. Inspect and Replace Brake Pads

Remove the caliper bolts with a socket set.
Carefully slide the caliper off the rotor.
Inspect brake pads for thickness; if less than 3mm, replace them.
- Tools Required: Socket set, caliper tool (if compressing pistons).
- Safety Warning: Ensure the brake fluid reservoir cap is loosened to avoid pressure build-up when compressing the caliper piston.
To replace, remove old pads and install new ones, ensuring they are properly seated.

5. Inspect and Replace Rotors (if necessary)

Check the rotor surface for grooves or warping.
If damaged, remove rotor by unscrewing the retaining screws or bolts.
Install new rotor, ensuring it is properly secured.
- Tools Required: Torque wrench for proper torque specifications.

6. Reassemble and Lower Vehicle

Reattach the caliper, ensuring it properly aligns with the new pads.
Reinstall the wheel and tighten lug nuts to the manufacturer’s torque specifications.
Lower the vehicle and remove jack stands.

7. Test the Brakes

Pump the brake pedal to ensure proper engagement of the pads against the rotors.
Start the vehicle and perform a test drive to ensure the grinding noise is resolved.
