Solution

1. Preparation

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

2. Raise the Vehicle

Use a jack to lift the front of the vehicle and secure it on jack stands.
Remove the front wheels using a lug wrench.

3. Inspect and Replace Brake Rotors

Remove Brake Caliper:
- Use a socket set to remove caliper mounting bolts.
- Hang the caliper using a bungee cord to avoid stress on the brake line.
Remove Brake Rotor:
- Remove any retaining screws and slide the rotor off the hub.
Inspect Rotor:
- Check for warping or excessive wear. Replace if necessary.
- Clean the hub surface using a wire brush.
Install New Rotor:
- Position the new rotor on the hub and secure it with retaining screws.

4. Inspect and Replace Brake Pads

Remove Old Brake Pads:
- Take out the old pads from the caliper bracket.
Install New Brake Pads:
- Apply brake grease to the back of the new pads and insert them into the caliper bracket.
Reattach Brake Caliper:
- Position the caliper back over the new pads and secure it with mounting bolts to the specified torque (typically 25-35 lb-ft).

5. Reassemble and Lower Vehicle

Reinstall the front wheels and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the manufacturer's specifications (typically 76-86 lb-ft).

6. Test Drive

Perform a test drive to ensure that the shaking has been resolved and brakes function effectively.
