Solution

1. Preparation

Gather all tools and parts needed.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Wear safety goggles and gloves for protection.

2. Raise the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on which brakes are grinding.
Secure with jack stands to ensure stability.

3. Remove the Wheel

Use a socket set to loosen and remove the lug nuts on the wheel.
Take off the wheel to gain access to the brake components.

4. Inspect and Remove Brake Components

Inspect Brake Pads and Rotors:
- Check the condition of the brake pads and rotors for wear.
Remove Brake Caliper:
- Use a socket wrench to remove the caliper mounting bolts.
- Carefully slide the caliper off the rotor and support it with a bungee cord (do not let it hang by the brake line).

5. Replace Brake Pads and/or Rotors

Brake Pads Replacement:
- Remove the worn brake pads from the caliper bracket.
- Insert new brake pads into the caliper bracket, ensuring proper orientation.
Brake Rotor Replacement:
- If the rotor is damaged, remove the retaining screws if present, and slide the rotor off the hub.
- Install the new rotor and secure it with the retaining screws.

6. Reinstall Brake Caliper

Compress the caliper piston using a brake caliper tool.
Slide the caliper back over the new brake pads and rotor.
Reinstall the caliper mounting bolts and torque them to the manufacturer's specifications (typically around 25-30 Nm).

7. Reinstall the Wheel

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle to the ground and then torque the lug nuts to the specified value (usually 90-100 Nm).

8. Final Checks

Pump the brake pedal a few times to ensure proper brake pad seating.
Check brake fluid levels and top off if necessary.
