Solution

1. Preparation

Gather tools and parts:
- Tools Required: Jack and jack stands, socket set, brake cleaner, torque wrench, and safety glasses.
- Safety Warnings: Ensure the vehicle is on a flat surface and the parking brake is engaged.

2. Lift the Vehicle

Use the jack to elevate the vehicle and secure it on jack stands.
Remove the wheels to access the brake components.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket set.
Slide the caliper off and suspend it using a bungee cord (do not allow it to hang by the brake line).
Inspect the brake pads for thickness; if they are worn down to 3mm or less, replace them.
- Sub-steps:
  - Remove old pads by sliding them out of the caliper bracket.
  - Clean the caliper bracket with brake cleaner.
  - Install new pads in the bracket ensuring proper orientation.

4. Inspect and Replace Brake Rotors (if necessary)

Check the rotors for wear; if warped or damaged, replace them.
- Sub-steps:
  - Remove the rotor by unscrewing any retaining screws (if present) and sliding it off the hub.
  - Install the new rotor, ensuring it is properly seated against the hub.

5. Reassemble Braking Components

Reattach the caliper over the new pads and rotor.
Torque the caliper bolts to the manufacturer's specifications (typically around 25-30 ft-lbs).
Reinstall the wheels and lower the vehicle.

6. Final Checks

Pump the brake pedal to ensure proper pad seating.
Check brake fluid level and top off if necessary.
Test drive the vehicle to confirm the grinding noise is eliminated.
