Solution

1. Preparation

Gather Tools and Parts:
- Tools: Jack and jack stands, lug wrench, socket set, torque wrench, brake cleaner, and a c-clamp.
- Parts: New brake pads, and if necessary, new rotors.
Safety Warnings: Ensure the vehicle is parked on a flat surface and engage the parking brake. Disconnect the battery if working on electronic components.

2. Lift and Secure the Vehicle

Sub-steps:
1. Loosen the lug nuts on the wheel where the grinding noise is occurring.
2. Use the jack to lift the vehicle and place it securely on jack stands.
3. Remove the wheel by fully unscrewing the lug nuts.

3. Remove Brake Components

Sub-steps:
1. Remove the brake caliper by unscrewing the caliper bolts.
2. Suspend the caliper using a bungee cord or rope to avoid straining the brake line.
3. Take off the old brake pads from the caliper bracket.
4. If necessary, remove the brake rotor by unbolting it from the hub.

4. Inspect and Replace Components

Sub-steps:
1. Inspect the brake rotor for any warping or deep grooves; replace if necessary.
2. Clean the brake caliper and rotor mounting surfaces with brake cleaner.
3. Install new brake pads into the caliper bracket.
4. If replacing rotors, install the new rotor onto the hub and secure it.

5. Reassemble and Test

Sub-steps:
1. Reattach the brake caliper over the new pads and torque the caliper bolts to manufacturer specifications.
2. Reinstall the wheel and torque the lug nuts in a star pattern to the manufacturer’s specifications.
3. Lower the vehicle and reconnect the battery if it was disconnected.
