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 to protect against debris.

2. Lift the Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheel corresponding to the grinding brakes.

3. Remove Brake Components

Remove the Brake Caliper:
- Use a socket set to remove the caliper bolts.
- Carefully detach the caliper and suspend it using a bungee cord to avoid straining the brake line.
Remove the Brake Pads:
- Slide the old brake pads out of the caliper bracket.
Remove the Brake Rotor:
- If necessary, remove the rotor retaining screws and slide the rotor off the hub.

4. Inspect and Clean

Inspect Brake Components:
- Examine the brake pads, rotors, and calipers for damage or excessive wear.
Clean the Components:
- Use brake cleaner to clean the brake caliper, rotor, and bracket areas to remove dust and debris.

5. Install New Parts

Install New Brake Rotor:
- Place the new rotor onto the hub and secure it with retaining screws if applicable.
Install New Brake Pads:
- Position the new brake pads into the caliper bracket.
Reattach Brake Caliper:
- Carefully position the caliper over the new brake pads and tighten the caliper bolts to the manufacturer’s specified torque value (typically around 25-35 Nm).

6. Reassemble and Lower the Vehicle

Replace the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and tighten the lug nuts to the manufacturer’s specified torque (usually around 120 Nm).
