Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Wear safety goggles and gloves.

2. Lift the Vehicle

Use a jack to lift the front or rear (depending on which brakes are affected) of the vehicle.
Secure with jack stands for safety.

3. Remove Wheel

Use a socket set to remove the lug nuts from the wheel.
Take off the wheel to access the brake components.

4. Inspect and Replace Brake Pads

Inspection:
- Check brake pads for thickness; replace if less than 3mm.
- Look for uneven wear or damage.
Replacement:
- Remove the caliper bolts with a socket.
- Slide the caliper off the rotor and support it with a hanger (do not let it dangle by the brake line).
- Remove the old brake pads from the caliper bracket.
- Install new brake pads into the caliper bracket.
- Reinstall the caliper over the new pads and tighten caliper bolts to the manufacturer’s torque specification (usually around 25-30 Nm).

5. Inspect and Replace Brake Rotors (if necessary)

Check the rotor surface for deep grooves or warping.
If replacement is needed, remove the caliper bracket and then the rotor.
Install new rotors by aligning with the hub and secure them with any retaining screws.
Reattach the caliper bracket.

6. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the manufacturer’s specification (typically around 90-120 Nm).
Pump the brake pedal to ensure proper seating of the brake pads.
Test drive the vehicle to confirm the grinding noise has been resolved.
