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.

2. Remove Wheel

Loosen lug nuts while the vehicle is on the ground.
Raise the vehicle using a jack and secure it on jack stands.
Remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Rotors

Inspection: Measure rotor thickness with a micrometer; replace if below minimum specifications.
Removal: Unbolt brake caliper using a socket set and suspend it with a wire (do not let it hang).
Remove the brake rotor by unscrewing the retaining screws, if equipped.
Installation: Install new rotors, ensuring they are clean and free from oil or grease. Torque the retaining screws to manufacturer specifications.

4. Inspect and Replace Brake Pads

Remove old brake pads from the caliper bracket.
Compare new pads to old ones for wear.
Installation: Apply brake grease to the back of the new pads to reduce noise. Install the new pads and reattach the caliper.

5. Reinstall Wheel

Place the wheel back onto the hub.
Hand-tighten the lug nuts, then lower the vehicle.
Tighten lug nuts to the manufacturer’s torque specifications in a crisscross pattern.

6. Test Drive

Conduct a test drive to check for any remaining vibration during braking.
