Solution

1. Preparation

Gather tools and parts:
- Tools: Jack, jack stands, lug wrench, socket set, torque wrench, brake cleaner, and a caliper tool.
- Safety gear: Gloves and safety goggles.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Lift the Vehicle

Use the lug wrench to loosen the lug nuts on the wheel you will be working on.
Elevate the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the brake components.

3. Inspect Brake Components

Brake Pads:
- Remove the caliper bolts using a socket set.
- Remove the brake caliper and hang it securely; do not let it dangle from the brake line.
- Inspect brake pads for wear; replace if the friction material is less than 3mm thick.
Brake Rotors:
- Check the surface of the rotors for grooves or scoring.
- Use a micrometer to measure rotor thickness; replace if below specifications or resurface if feasible.
Brake Calipers:
- Check calipers for proper movement and signs of corrosion.
- Ensure pistons are not stuck; clean and lubricate if necessary.

4. Replacement of Worn Parts

If brake pads are worn, replace them with new ones following the manufacturer's specifications.
If rotors are damaged, either replace them or have them resurfaced.
Reassemble the caliper and ensure all bolts are torqued to the manufacturer’s specifications.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and fully tighten the lug nuts to the specified torque.
Test the brakes by gently applying pressure to ensure the grinding noise is resolved.
