Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, socket set, brake cleaner, safety goggles, gloves.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the battery to prevent any electrical issues while working on the brakes.

2. Remove Wheel

Loosen lug nuts on the affected wheel slightly while the car is on the ground.
Use the 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

Remove the caliper by unscrewing the caliper bolts using the socket set.
Slide the caliper off the brake rotor and support it with a bungee cord to avoid stress on the brake line.
Remove the old brake pads from the caliper bracket.
Inspect the brake pads for wear; if they are below the minimum thickness (usually 3mm), replace them with new pads.
Apply brake lubricant to the backing plates of the new pads to reduce noise.

4. Inspect and Replace Brake Rotors (if necessary)

Check the brake rotor surface for deep grooves or warping.
If the rotor is damaged, remove it by unbolting the rotor from the hub.
Install the new rotor, ensuring it is properly aligned.
Torque the rotor bolts to the manufacturer's specifications (usually around 75-90 ft-lbs).

5. Reassemble Braking System

Reposition the caliper over the new brake pads and rotor.
Reinstall the caliper bolts and torque them to specification (usually around 30-40 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle off the jack stands and tighten the lug nuts to the manufacturer's torque specification (usually around 75-90 ft-lbs).

6. Final Checks

Reconnect the battery.
Pump the brake pedal several times to ensure proper brake pressure is built up.
Test drive the vehicle to confirm that the grinding noise has been resolved.
