Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, socket set, torque wrench, brake cleaner, safety goggles, gloves.
Sub-steps:
- Park the vehicle on a flat surface and engage the parking brake.
- Remove the wheel where the grinding noise is occurring using the lug wrench.
- Secure the vehicle with jack stands after raising it with a jack.

2. Inspect and Replace Brake Pads

Sub-steps:
- Remove the caliper bolts with a socket wrench and carefully take off the caliper.
- Inspect the brake pads for thickness; if they are worn down to 3mm or less, replace them.
- Remove the old brake pads from the caliper bracket and clean the area using brake cleaner.
- Install new brake pads, ensuring they are seated properly in the caliper bracket.

3. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
- If the rotors are scored or worn beyond the manufacturer's specifications, remove the rotor by unscrewing the retaining screws if present.
- Clean the hub surface and install new rotors, ensuring they are fastened securely.
- Torque the rotor screws to the manufacturer's specifications.

4. Reassemble Braking System

Sub-steps:
- Reattach the caliper over the new brake pads, ensuring proper alignment.
- Install and torque the caliper bolts to the manufacturer's specifications.
- Reinstall the wheel and torque the lug nuts to the specified value.
