Solution

1. Preparation

Gather tools and parts needed before starting the repair.
- Tools Required: Jack and jack stands, lug wrench, socket set, brake caliper tool, torque wrench, cleaning brush, brake cleaner, safety glasses, gloves.
- Safety Warnings: Ensure the vehicle is on a flat surface and engage the parking brake.

2. Lift the Vehicle

Use the lug wrench to loosen the lug nuts on the front or rear wheels (depending on where the grinding occurs).
Lift the vehicle with a jack and secure it with jack stands.
Remove the wheels to access the brake components.

3. Inspect and Replace Brake Pads

Remove the brake caliper by unscrewing the caliper bolts with a socket.
Carefully slide the caliper off the rotor and support it with a bungee cord or similar to avoid straining the brake line.
Remove the old brake pads from the caliper bracket.
Inspect the brake rotor for grooves or damage; replace if necessary.
Install new brake pads into the caliper bracket, ensuring proper alignment.

4. Reassemble Brake Components

Slide the caliper back over the new brake pads and rotor.
Reinstall the caliper bolts and tighten to the manufacturer's torque specifications (typically around 25-35 Nm).
Reinstall the wheel and hand-tighten the lug nuts.

5. Lower the Vehicle and Final Checks

Lower the vehicle off the jack stands.
Tighten the lug nuts to the manufacturer's torque specifications (typically around 100-120 Nm).
Pump the brake pedal several times to ensure proper brake pad seating.
