Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
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 and Replace Brake Pads

Remove the brake caliper by unscrewing the caliper bolts using a socket wrench.
Carefully lift the caliper off the brake rotor and support it without straining the brake line.
Remove the old brake pads from the caliper bracket.
Clean the caliper bracket and inspect the slide pins for proper movement.
Install new brake pads, ensuring they are properly seated.

4. Inspect and Replace Rotors (if necessary)

Check the brake rotors for damage. If they are scored or below the minimum thickness, replace them.
Remove the rotor by unscrewing the retaining screws (if applicable).
Install new rotors, ensuring they are securely fastened.

5. Reassemble and Test Brakes

Reattach the brake caliper over the new brake pads and secure it with the caliper bolts. Torque to manufacturer specifications (usually 20-30 ft-lbs).
Reinstall the wheel and lug nuts, tightening them in a crisscross pattern to ensure even pressure.
Lower the vehicle and remove the jack stands.

6. Final Checks

Pump the brake pedal a few times to seat the brake pads against the rotors.
Check brake fluid levels and top off if needed.
Test drive the vehicle to confirm the grinding noise has been resolved.
