Solution

1. Preparation

Tools Required: Safety goggles, gloves, jack and jack stands, wheel chocks, lug wrench, socket set.
Safety Warnings: Ensure the vehicle is on a flat surface and engage the parking brake. Disconnect battery if working on electrical components.

2. Remove Wheel

Loosen lug nuts slightly while the vehicle is on the ground.
Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the caliper mounting bolts using a socket set.
2. Carefully slide the caliper off the rotor and suspend it with a wire or bungee to avoid stress on the brake line.
3. Remove the old brake pads from the caliper bracket.
4. Inspect the caliper for any damage or leaks and replace if necessary.
5. Install new brake pads, ensuring they are properly seated in the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
1. If rotors are scored or excessively worn, remove the caliper bracket.
2. Slide the rotor off the hub. If it’s stuck, tap gently with a rubber mallet.
3. Install new rotors, ensuring they are clean and free of grease.
4. Reattach the caliper bracket over the new rotor.

5. Reassembly

Replace the caliper onto the rotor, ensuring it is correctly positioned.
Reinstall the caliper mounting bolts and torque to manufacturer specifications (consult vehicle service manual for specific torque values).
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the specified value.

6. Test Brakes

Pump the brake pedal several times to ensure pads are seated properly.
Test the vehicle at low speeds to ensure brakes are functioning correctly and the grinding noise is eliminated.
