Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Wear safety goggles and gloves for protection.

2. Remove Wheel

Sub-steps:
1. Loosen lug nuts with a socket set while the wheel is still on the ground.
2. Lift the vehicle using a jack and secure it with jack stands.
3. Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the caliper bolts with a socket wrench and carefully slide the caliper off the rotor.
2. If pads are worn down (less than 3mm thickness), remove the old pads.
3. Install new brake pads, ensuring they are oriented correctly and seated properly in the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
1. Check the rotor for scoring or uneven wear. If damaged, remove the rotor by unscrewing the retaining screws (if applicable).
2. Install new rotors, ensuring they are clean and free of oil.
3. Torque the rotor bolts to the manufacturer’s specifications.

5. Reassemble Brake Components

Sub-steps:
1. Reattach the caliper over the new pads and rotor.
2. Tighten caliper bolts to specified torque settings.
3. Reinstall the wheel and torque lug nuts in a star pattern.

6. Final Checks

Sub-steps:
1. Lower the vehicle from the jack stands.
2. Pump the brake pedal a few times to ensure proper pad seating and brake pressure.
3. Conduct a test drive to ensure the grinding noise is resolved.
