Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Use wheel chocks to prevent the vehicle from rolling.

2. Remove Wheel

Tools Required: Jack, jack stands, lug wrench.
Sub-steps:
1. Loosen the lug nuts slightly while the wheel is on the ground.
2. Raise the vehicle with a jack and secure it with jack stands.
3. Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Tools Required: Socket set, torque wrench, brake cleaner.
Sub-steps:
1. Inspect brake pads for thickness; if less than 3mm, replace them.
2. Remove the caliper by unbolting it from the bracket.
3. Slide the caliper off the rotor and hang it using a bungee cord (do not let it hang by the brake line).
4. Remove the old brake pads from the caliper bracket.
5. Install new brake pads into the bracket, ensuring they are properly aligned.

4. Inspect and Replace Brake Rotors (if necessary)

Tools Required: Rotor puller (if necessary), torque wrench.
Sub-steps:
1. Check the rotor surface for deep grooves or scoring.
2. If damaged, unbolt the rotor from the hub and replace it with a new rotor.
3. Clean the new rotor with brake cleaner before installation.

5. Reassemble Brake Components

Tools Required: Torque wrench.
Sub-steps:
1. Reinstall the caliper over the new brake pads and torque the bolts to the manufacturer's specifications (typically between 70-80 ft-lbs).
2. Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Test

Tools Required: None.
Sub-steps:
1. Lower the vehicle from the jack stands using the jack.
2. Tighten lug nuts to the specified torque.
3. Pump the brake pedal several times to seat the pads.
4. Test the brakes at low speed for proper operation and to ensure the grinding noise is resolved.
