Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and engage the parking brake.
Tools Required: Jack, jack stands, lug wrench, OBD-II scanner, socket set, torque wrench.

2. Remove Wheel

Loosen the lug nuts with a lug wrench (do not fully remove yet).
Raise the vehicle with a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel to access the brake components.

3. Inspect Brake Components

Brake Pads:
- Remove the caliper by unscrewing the caliper bolts.
- Check the thickness of the brake pads; replace if worn down to 3mm or less.
Brake Rotors:
- Inspect the surface of the rotor for grooves, rust, or cracking.
- Measure rotor thickness; if below minimum specification, replace.
Calipers:
- Check for signs of leaks around the caliper seals.
- Ensure the caliper slides smoothly on its mounting points.

4. Replace Components

Brake Pads Replacement:
- If the brake pads are worn, remove the old pads and install new ones.
- Ensure the pads are properly seated in the caliper bracket.
Rotor Replacement:
- If the rotor is damaged, remove it from the hub by unscrewing the retaining screws.
- Install the new rotor, ensuring it is torqued to manufacturer specifications (typically around 85-100 ft-lbs).

5. Reassemble and Test

Reinstall the caliper and torque the caliper bolts to manufacturer specifications (usually 30-35 ft-lbs).
Reattach the wheel and torque the lug nuts in a star pattern to ensure even pressure.
Lower the vehicle and perform a test drive to ensure the grinding noise is resolved.
