Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Wear safety glasses and gloves.

2. Lift the Vehicle

Use a floor jack to lift the front of the vehicle and securely place jack stands under the frame.
Remove the front wheels using a socket wrench.

3. Inspect and Replace Brake Rotors

Inspection:
- Use a dial indicator to measure rotor runout. If warping exceeds manufacturer specifications, replace the rotors.
Replacement:
- Remove caliper bolts and slide off the caliper. Support it with a bungee cord or rope (do not let it hang by the brake line).
- Remove the rotor retaining screws (if applicable) and slide the rotor off the hub.
- Install the new rotor, ensuring it is seated properly. Reinstall retaining screws.

4. Replace Brake Pads

Remove the brake pads from the caliper bracket.
Check the caliper pins for lubrication; apply brake grease if necessary.
Install new brake pads into the caliper bracket.

5. Reassemble Components

Reinstall the caliper over the new pads and secure the caliper bolts to the manufacturer’s torque specifications.
Reinstall the front wheels and lower the vehicle.

6. Test the Braking System

Before driving, pump the brake pedal to ensure proper brake pad seating.
Test drive the vehicle to ensure the vibration during braking has been resolved.
