Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, brake cleaner, safety glasses, gloves.
Safety Warnings: Ensure the vehicle is on a flat surface and the parking brake is engaged before lifting the vehicle.

2. Raise the Vehicle

Use a jack to lift the front or rear of the vehicle (depending on which brakes are making noise).
Securely place jack stands under the vehicle for safety.

3. Remove the Wheel

Using a lug wrench, loosen and remove the lug nuts.
Take off the wheel to access the brake assembly.

4. Inspect the Brake Pads

Remove the caliper by loosening the caliper bolts with a socket set.
Carefully slide the caliper off the brake rotor and support it (do not let it hang by the brake line).
Inspect the brake pads for wear; if the friction material is worn down to 1/8 inch or less, replace them.

5. Inspect the Brake Rotors

Check the brake rotors for grooves or scoring. If they appear damaged, they may need to be resurfaced or replaced.
Measure rotor thickness with a caliper to ensure they meet manufacturer specifications.

6. Reassemble and Test

If replacing pads or rotors, install new components. Ensure to torque the caliper bolts to the manufacturer’s specifications.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and then fully tighten the lug nuts in a crisscross pattern.

7. Final Check

Pump the brake pedal a few times to reset the brake pads against the rotor.
Test drive the vehicle at low speed to ensure the grinding noise is resolved.
