Solution

1. Preparation

Gather tools and parts required.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Wear safety glasses and gloves for protection.

2. Remove Wheel

Use a jack to lift the front or rear (depending on which brakes are grinding) of the vehicle.
Secure the vehicle on jack stands.
Remove the lug nuts using a socket wrench and take off the wheel.

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Check the thickness of the brake pads. If they are less than 3mm, they should be replaced.
Remove Old Brake Pads:
- Locate the caliper bolts and remove them using a socket wrench.
- Carefully slide the caliper off the brake rotor and support it with a bungee cord (do not let it hang).
- Remove the old brake pads from the caliper bracket.
Install New Brake Pads:
- Apply brake grease to the back of the new pads to prevent noise.
- Place the new brake pads into the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Check Rotors:
- If rotors are scored or below the minimum thickness, they need replacement.
Remove Old Rotors:
- Remove any retaining screws or clips.
- Slide the rotor off the hub.
Install New Rotors:
- Position the new rotor on the hub.
- Secure with retaining screws if applicable.

5. Reassemble Braking System

Reinstall the caliper over the new brake pads.
Torque the caliper bolts to the manufacturer's specifications (typically around 25-35 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Test

Lower the vehicle off the jack stands.
Torque the lug nuts to the recommended specifications (usually 80-100 ft-lbs).
Pump the brake pedal several times to ensure proper pad seating.
