Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the battery to prevent accidental electrical shorts.

2. Remove Wheel

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

3. Inspect and Replace Brake Pads

Inspect pads:
- Check the thickness of the brake pads. If they are less than 3mm, they should be replaced.
Remove pads:
- Unbolt the caliper using a socket wrench.
- Slide the caliper off the rotor and support it (do not hang it by the brake line).
- Remove the old brake pads from the caliper bracket.
Install new pads:
- Apply brake grease to the back of the new pads.
- Slide the new pads into the caliper bracket.

4. Inspect and Replace Brake Rotors

Check rotors:
- Measure the thickness of the rotors. If below the manufacturer’s specifications or if they are scored, they need to be replaced.
Remove rotors:
- Unbolt the caliper bracket and remove it.
- Slide the rotor off the hub. If it's stuck, gently tap it with a hammer.
Install new rotors:
- Place the new rotor onto the hub, ensuring it is seated properly.
- Reinstall the caliper bracket and torque the bolts to the manufacturer’s specifications.

5. Reassemble and Test

Reinstall the caliper over the new pads and torque the caliper bolts.
Reattach the wheel and torque the lug nuts in a crisscross pattern.
Reconnect the battery.
Lower the vehicle and perform a test drive to ensure the grinding noise is resolved.
