Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Raise the vehicle using a jack and support it with jack stands.

2. Remove Wheel

Use a lug wrench to remove the wheel bolts and take off the wheel.
Tools Required: Lug wrench, jack, jack stands.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket set.
Gently slide the caliper off the rotor, being careful not to stretch the brake line.
Remove the old brake pads from the caliper bracket.
Install new brake pads, ensuring they are seated properly.
Reattach the caliper over the new pads and secure it with bolts, tightening to manufacturer specifications.

4. Inspect and Resurface/Replace Rotors

Remove the rotor from the hub if it is damaged or scored.
If the rotor is in good condition, resurface it using a brake lathe to eliminate any scoring.
If replacement is necessary, install new rotors on the hub, ensuring they are clean from debris.
Torque rotor retaining screws to manufacturer specifications if applicable.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the specified value.
Pump the brake pedal to seat the brake pads against the rotor.
Test drive the vehicle to verify that the grinding noise has been resolved.
