Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Wear safety gloves and goggles for protection.

2. Remove Wheel

Use a lug wrench to loosen wheel lug nuts slightly while the vehicle is on the ground.
Lift the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Inspection: Check the thickness of the brake pads; if they are below 3mm, replacement is necessary.
Removal: Unbolt the caliper using a socket set and slide it off the rotor.
Replace: Remove the old brake pads from the caliper bracket and install new pads, ensuring they are oriented correctly.
Reinstallation: Reattach the caliper over the new brake pads and tighten bolts to manufacturer specifications (typically 20-30 lb-ft).

4. Inspect and Replace Brake Rotors (if needed)

Inspection: Check the rotor surface for grooves or scoring. If damaged, replacement is required.
Removal: Unbolt the rotor from the hub using a socket set and remove it.
Replace: Install the new rotor and secure it according to manufacturer specifications.
Reinstall: Reattach the caliper with new pads over the new rotor.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the specified torque (typically 80-100 lb-ft).
Pump the brake pedal to ensure proper pad seating and brake fluid distribution.
Test drive the vehicle to ensure the grinding noise is resolved.
