Solution

1. Preparation

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

2. Remove Wheel

Loosen lug nuts with a socket wrench.
Raise the vehicle using a jack and secure with jack stands.
Remove the wheel to access the brake assembly.

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Check thickness; if below the manufacturer's minimum specification (typically 3mm), replace.
Replace Brake Pads:
- Remove the caliper bolts using the appropriate socket.
- Slide the caliper off the rotor and support it without straining the brake line.
- Remove the old pads from the caliper bracket.
- Install new brake pads in their respective positions.
- Compress the caliper piston using a C-clamp to fit over the new pads.

4. Inspect and Replace Brake Rotors (if necessary)

Inspect Rotors:
- Measure rotor thickness; replace if below specification or if surface is scored.
Replace Rotors:
- Remove the caliper bracket if necessary.
- Unscrew the rotor retaining screws (if equipped) and slide the rotor off the hub.
- Install the new rotor, ensuring it seats properly.
- Reattach caliper bracket and caliper.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque lug nuts to the manufacturer’s specification (usually around 80-100 ft-lbs).
Pump the brake pedal several times to ensure proper brake operation before driving.
Test drive the vehicle to confirm the grinding noise has been resolved.
