Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Use wheel chocks for safety.

2. Remove Wheel

Tools Required: Jack and jack stands, lug wrench.
Sub-steps:
1. Loosen the lug nuts on the wheel where the grinding noise is occurring.
2. Raise the vehicle using a jack and securely place it on jack stands.
3. Fully remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Tools Required: Brake pad spreader, socket set, torque wrench.
Sub-steps:
1. Remove the caliper bolts using a socket set.
2. Slide the caliper off the rotor and support it without straining the brake line.
3. Remove the old brake pads from the caliper bracket.
4. Inspect the caliper for any damage or seized components; replace if necessary.
5. Install new brake pads, ensuring they fit snugly in the caliper bracket.

4. Check and Replace Brake Rotors (if necessary)

Tools Required: Rotor puller (if needed), torque wrench.
Sub-steps:
1. Inspect the rotor for deep grooves or warping; replace if damaged.
2. If replacing, unbolt the rotor from the hub.
3. Install the new rotor and torque the mounting bolts to manufacturer specifications.

5. Reassemble and Test

Tools Required: Torque wrench, lug wrench.
Sub-steps:
1. Reinstall the caliper over the new brake pads.
2. Tighten caliper bolts to recommended torque settings.
3. Reinstall the wheel and hand-tighten the lug nuts.
4. Lower the vehicle and fully tighten the lug nuts in a crisscross pattern.
