Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface.
Lift the vehicle using a jack and secure it with jack stands.
Remove the wheel where the grinding noise is occurring.

2. Inspect and Replace Brake Pads

Remove the caliper mounting bolts using a socket set.
Carefully slide the caliper off the brake pads and rotor.
Inspect the brake pads for thickness; replace if less than 3mm.
If needed, use a brake pad spreader tool to compress the caliper piston.
Install new brake pads, ensuring proper orientation and alignment.

3. Inspect and Replace Brake Rotors

Check the rotors for uneven wear or grooves.
If damaged, remove the rotor by unscrewing the retaining screws.
Install the new rotor, ensuring it is properly seated.
Tighten the rotor screws to the manufacturer's specified torque.

4. Reassemble Brake Components

Reattach the caliper over the new brake pads.
Tighten the caliper mounting bolts to the specified torque.
Reinstall the wheel and lower the vehicle.
