Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the battery to prevent electrical issues.

2. Remove Wheel

Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheel by loosening the lug nuts with a socket wrench and then removing them completely.

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Remove the caliper bolts using a socket set.
- Carefully slide the caliper off the rotor and suspend it using a bungee cord or rope.
- Inspect the brake pads for wear; replace if less than 3mm thickness remains.
Replace Brake Pads:
- Remove the old pads from the caliper bracket.
- Install new pads, ensuring they are properly aligned.
- Apply brake grease on the backing of the pads to reduce noise.

4. Inspect and Replace Brake Rotors (if necessary)

Inspect Rotors:
- Check for grooves, scoring, or excessive wear. If damaged, they should be replaced.
Replace Rotors:
- Remove the caliper bracket by unscrewing the bolts.
- Slide the rotor off the hub (may require tapping with a rubber mallet).
- Install new rotors, ensuring they are clean and free of grease.
- Reattach the caliper bracket and torque bolts to the manufacturer’s specifications.

5. Reassemble and Test

Reinstall the caliper and secure it with bolts.
Reattach the wheel and lower the vehicle.
Torque the lug nuts to the manufacturer’s specifications.
Reconnect the battery.
Test drive the vehicle to ensure the grinding noise has been resolved.
