Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench, brake cleaner, gloves, safety glasses.
Park the vehicle on a level surface, engage the parking brake, and turn off the ignition.
Wear gloves and safety glasses for protection.

2. Lift the Vehicle

Use the lug wrench to loosen the lug nuts on the wheel where the grinding noise is present.
Raise the vehicle with a jack and secure it with jack stands.
Remove the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the caliper bolts using the socket set.
2. Carefully slide the caliper off the rotor, ensuring not to damage the brake line.
3. Inspect the brake pads for thickness; replace if they are worn down (less than 3 mm).
4. If replacement is necessary, remove the old pads and install new pads, ensuring they fit snugly.
5. Reinstall the caliper and torque the bolts to the manufacturer’s specifications (usually around 25-35 ft-lbs).

4. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
1. Check the rotors for deep grooves or warping.
2. If replacement is needed, remove the caliper bracket and rotor using the socket set.
3. Clean the new rotor with brake cleaner to remove any protective coating.
4. Install the new rotor and reassemble the caliper bracket, torquing to the manufacturer's specifications.

5. Final Assembly

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and remove the jack.
Torque the lug nuts to the manufacturer’s specifications (usually around 76-83 ft-lbs).
