Solution

1. Preparation

Tools Required: Jack, jack stands, wheel chocks, socket set, torque wrench, brake cleaner, and safety glasses.
Safely park the vehicle on a flat surface and engage the parking brake.

2. Raise the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on which brakes are making noise.
Secure the vehicle with jack stands and place wheel chocks to prevent movement.

3. Remove Wheel

Using a socket set, remove the lug nuts and take off the wheel to access the brake assembly.

4. Inspect Brake Components

Brake Pads: Remove the caliper and inspect the brake pads for wear. If they are less than 3mm thick, they need replacement.
Brake Rotors: Check the rotors for any grooves or warping. If they appear damaged or below the minimum thickness, they should be replaced.
Caliper Functionality: Ensure the caliper slides smoothly on its pins. Clean and lubricate the caliper pins if necessary.

5. Replace Brake Pads and Rotors (if necessary)

Remove the old brake pads and rotors.
Install new rotors if required, ensuring they are seated correctly.
Insert new brake pads into the caliper bracket.
Reinstall the caliper and torque the bolts to the manufacturer’s specifications (typically 25-30 Nm).

6. Reassemble and Lower the Vehicle

Replace the wheel and hand-tighten the lug nuts.
Lower the vehicle off the jack stands using the jack.
Torque the lug nuts to the manufacturer’s specifications (typically 100-120 Nm).

7. Test the Brakes

Pump the brake pedal to ensure proper seating of the pads.
Test drive the vehicle at low speeds to ensure the grinding noise has ceased.
