Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and set the parking brake.
Disconnect the battery to avoid electrical issues during repair.

2. Remove Wheels

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 wheels.

3. Inspect and Replace Brake Pads

Inspection:
- Use a caliper tool to remove the caliper bolts.
- Carefully slide the caliper off the rotor and hang it with a bungee cord to avoid straining the brake line.
- Check the brake pads for thickness; replace if less than 3mm.
Replacement:
- Remove old brake pads from the caliper bracket.
- Clean the caliper and bracket with brake cleaner.
- Install new brake pads, ensuring they are correctly positioned.
- Reattach the caliper over the new pads and tighten the caliper bolts to the manufacturer’s torque specifications (typically around 20-30 ft-lbs).

4. Inspect and Replace Brake Rotors (if necessary)

If rotors are damaged, remove them by unscrewing the rotor retaining screws (if equipped).
Clean the hub surface with brake cleaner.
Install new rotors, ensuring they seat properly.
If resurfacing is an option, ensure the rotors are within specifications for thickness.

5. Reassemble and Test

Reattach the wheels and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to specified values (usually around 80-100 ft-lbs).
Reconnect the battery.
Conduct a test drive to ensure the grinding noise is resolved.
