Solution

1. Preparation

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

2. Remove Wheel

Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts using a socket wrench and take off the wheel.

3. Inspect Brake Components

Brake Pads: Remove the caliper bolts and slide the caliper off the rotor. Inspect the brake pads for thickness; replace if worn below manufacturer specifications (typically 3mm).
Brake Rotors: Check the rotors for grooves or scoring. If damaged, they may need to be resurfaced or replaced.
Calipers: Ensure calipers move freely. Lubricate sliding pins if necessary.

4. Replace Worn Components

If brake pads are worn, replace them with new ones. Ensure they are properly seated in the caliper bracket.
If rotors are damaged, replace them. Torque new rotors to manufacturer specifications (typically around 80-100 ft-lbs).

5. Reassemble

Reinstall the caliper and torque the caliper bolts to manufacturer specifications.
Replace the wheel and lug nuts, tightening them in a crisscross pattern to ensure even pressure.
Lower the vehicle down from the jack stands.

6. Test Brakes

Pump the brake pedal several times to seat the new pads.
Test drive the vehicle at low speeds to ensure the grinding noise is gone.
