Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, brake cleaner, caliper tool, torque wrench.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Raise the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on where the grinding noise is coming from.
Secure the vehicle with jack stands to ensure stability.
Remove the wheel using a lug wrench.

3. Remove the Brake Components

Brake Pads:
1. Locate the caliper bolts using the socket set and remove them.
2. Carefully slide the caliper off the rotor; support it with a bungee cord or rope to avoid stressing the brake line.
3. Remove the old brake pads from the caliper bracket.
Rotors:
1. If replacing the rotor, remove the rotor retaining screws (if applicable).
2. Slide the rotor off the hub.

4. Inspect and Replace Components

Inspect the brake pads for uneven wear or damage; replace if they are worn below the manufacturer's specification (usually 3mm).
Check the rotors for grooves or warping. If damaged, replace with new rotors.
Clean the braking surfaces using brake cleaner to remove dust and debris.

5. Reassemble the Brake System

Install new brake pads into the caliper bracket.
If the rotor was replaced, install the new rotor onto the hub.
Reinstall the caliper over the new pads and torque the caliper bolts to the manufacturer’s specification (typically 20-30 ft-lbs, check specific vehicle specs).

6. Final Checks

Reinstall the wheel and torque the lug nuts to the manufacturer’s specification (typically 100-150 ft-lbs).
Lower the vehicle from the jack stands.
