Solution

1. Preparation

Gather tools and parts:
- Tools: Socket set, brake cleaner, torque wrench, jack and jack stands, C-clamp, OBD-II scanner.
- Parts: New brake pads, brake rotors (if necessary), brake fluid.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Raise the Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheel where the grinding sound is occurring.

3. Remove Brake Components

Brake Caliper Removal:
- Locate the caliper mounting bolts and remove them using the socket set.
- Carefully slide the caliper off the rotor and support it using a bungee cord to avoid straining the brake line.
Brake Pad Removal:
- Remove the old brake pads from the caliper bracket.
Rotor Removal:
- If the rotor is damaged, remove any retaining screws and slide the rotor off the hub.

4. Inspect and Replace

Inspect Components:
- Check the brake pads for thickness and replace if they are worn down beyond the manufacturer's specifications.
- Inspect the rotor surface; if it's scored or warped, replace it.
Install New Components:
- If replacing, install the new rotor onto the hub and secure it.
- Apply brake grease to the back of the new brake pads and install them into the caliper bracket.
Reattach Caliper:
- Reposition the caliper over the new pads and rotor, securing it with the mounting bolts. Torque to the manufacturer’s specifications.

5. Reassemble and Test

Replace the wheel and lower the vehicle back to the ground.
Pump the brake pedal a few times to seat the pads against the rotor.
Check brake fluid levels and top off if necessary.
