Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and secure with wheel chocks.
Disconnect the battery to avoid any electrical issues while working on the brakes.

2. Remove Wheel

Using a socket set, loosen the lug nuts on the wheel where the grinding sound is coming from.
Raise the vehicle with a jack and secure it on jack stands.
Remove the wheel to access the brake assembly.

3. Inspect and Replace Brake Pads

Remove any retaining clips or screws holding the brake caliper in place with the appropriate socket.
Slide the caliper off the rotor and suspend it using a bungee cord to avoid straining the brake line.
Remove the old brake pads from the caliper bracket.
Compare the thickness of the new brake pads with the old ones to ensure proper fitment.
Install the new brake pads into the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Check the rotor surface for grooves or scoring. If damaged, proceed with replacement.
Remove the caliper bracket by unscrewing the bolts and slide the rotor off the hub.
Install the new rotor, ensuring it is seated properly on the hub.

5. Reassemble Brake Components

Reattach the caliper bracket over the new rotor.
Reinstall the caliper over the new brake pads and tighten the bolts to the manufacturer's torque specifications.
Reinstall the wheel and tighten the lug nuts in a star pattern to ensure even pressure.

6. Final Checks

Reconnect the battery.
Pump the brake pedal several times to seat the new brake pads.
Check brake fluid level and add fluid if necessary.
