Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, torque wrench.
Safety Warnings: Ensure the vehicle is on a flat surface; engage parking brake and place wheel chocks behind the rear wheels.

2. Lift the Vehicle

Use the jack to lift the front of the vehicle and securely place it on jack stands.
Remove the front wheels with the lug wrench.

3. Inspect and Replace Brake Rotors

Inspect Rotors:
- Check for warping using a dial indicator gauge.
- If warped beyond specifications (usually 0.002 inches), replace the rotors.
Remove Rotors:
- Unscrew the caliper bracket bolts and remove the caliper (support it with a wire to avoid straining the brake line).
- Remove the rotor by unscrewing any retaining screws and pulling it off the hub.
Install New Rotors:
- Clean the new rotors with brake cleaner to remove any protective coating.
- Install the new rotor onto the hub and secure it with retaining screws.

4. Inspect and Replace Brake Pads

Remove Brake Pads:
- Remove the caliper from the bracket and slide out the old brake pads.
Install New Brake Pads:
- Apply brake grease to the backs of the new pads and install them into the caliper bracket.

5. Reassemble and Torque Components

Reinstall the caliper over the new brake pads and tighten caliper bolts to manufacturer specifications (typically around 30 Nm).
Reinstall the wheel and torque the lug nuts to the specified value (usually 120 Nm).

6. Lower the Vehicle and Test Brakes

Carefully lower the vehicle off the jack stands.
Pump the brake pedal several times to seat the brake pads against the rotors.
Test drive the vehicle to ensure that the shaking has been resolved.
