Flathead screwdriver
C-clamp or brake caliper tool
Brake pads (OEM recommended)
Brake rotors (if necessary)
Gloves and safety glasses

Repair Instructions

Step 1: Raise the Vehicle

Park the Car: Ensure the car is on a flat surface and engage the parking brake.
Loosen Lug Nuts: Use the lug wrench to slightly loosen the lug nuts on the front or rear wheels where the grinding noise is occurring.
Raise the Vehicle: Use the jack to lift the vehicle and secure it with jack stands.
Remove the Wheel: Take off the lug nuts and remove the wheel.

Step 2: Inspect the Brake Components

Visual Inspection: Check the brake pads for wear:
- If the friction material is worn down to the metal, the pads need to be replaced.
Check the Rotors: Inspect the brake rotors:
- Look for deep grooves or scoring. If they are damaged beyond resurfacing, they will need to be replaced.

Step 3: Replace Brake Pads and Rotors

Remove the Caliper:
- Use a socket wrench to remove the caliper bolts and gently lift the caliper off the rotor. Do not let it hang by the brake line.
Remove Old Brake Pads:
- Slide out the old pads from the caliper bracket.
Check the Caliper Piston:
- Use a C-clamp or brake caliper tool to compress the caliper piston back into its housing.
Install New Brake Pads:
- Slide the new brake pads into the caliper bracket. Ensure they are seated correctly.
Reinstall Caliper:
- Position the caliper back over the new pads and secure it with the caliper bolts. Torque them to the manufacturer’s specification (usually around 25-35 ft-lbs).

Step 4: Replace Rotors (if necessary)

Remove the Old Rotor:
- If replacing, remove the rotor by unscrewing the retaining screws (if equipped) and sliding it off the hub.
Install New Rotor:
- Place the new rotor onto the hub and secure it with screws.

Step 5: Reassemble the Wheel

Reinstall the Wheel: Place the wheel back on the hub and hand-tighten the lug nuts.
Lower the Vehicle: Remove the jack stands and lower the vehicle back to the ground.
Torque Lug Nuts: Use a torque wrench to tighten the lug nuts to the manufacturer’s specification (usually around 76-86 ft-lbs).

Step 6: Final Checks

Pump the Brakes: Before driving, pump the brake pedal several times to ensure the pads seat properly.
Test Drive: Take the vehicle for a short test drive to check for any remaining noises or issues.

Conclusion

If the grinding noise persists after replacing the brake pads and/or rotors, further diagnosis may be required, including checking the brake calipers, brake lines, or even potential issues with the ABS system. If unsure, consult a professional technician for more in-depth analysis.
