Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety glasses and gloves for protection.

2. Remove Wheel

Use a lug wrench to loosen the wheel lug nuts.
Lift the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the braking system.

3. Inspect and Replace Brake Pads

Inspection:
- Remove the caliper by unscrewing the caliper bolts (usually 14mm or 17mm).
- Slide the caliper off the rotor, taking care not to strain the brake line.
- Inspect the brake pads for thickness; replace if less than 3mm.
Replacement:
- Remove the old brake pads from the caliper bracket.
- Install new brake pads, ensuring they fit securely.
- Reattach the caliper over the new pads and torque the caliper bolts to the manufacturer’s specifications (usually around 25-30 ft-lbs).

4. Inspect and Replace Brake Rotors (if necessary)

Check the rotor surface for scoring or warping.
If damaged, remove the rotor by unscrewing the retaining screws (if applicable) and sliding it off the hub.
Install the new rotor, aligning it with the hub, and secure with screws.
Ensure a clean surface for the new pads.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer’s specifications (usually 76-90 ft-lbs).
Pump the brake pedal a few times to restore brake pressure.
Test drive the vehicle to ensure the grinding noise has been resolved.
