Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Ensure the engine is off and the keys are removed.

2. Raise Vehicle

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

3. Inspect Brake Components

Rotors: Remove the brake caliper by unbolting it from the bracket. Carefully hang it using a bungee cord to avoid stress on the brake line.
- Use a dial indicator to measure rotor runout; replace if warped beyond specifications (usually more than 0.004 inches).
Brake Pads: Check the thickness of the brake pads. Replace if they are worn down to less than 3mm.

4. Replace Components

Brake Rotors: If warped, remove the old rotors and install new ones. Torque the rotor retaining screws to the manufacturer's specifications.
Brake Pads: Install new brake pads. Apply brake grease to the back of the pads to prevent noise. Torque the caliper bolts to the manufacturer’s specifications.

5. Reassemble and Test

Reinstall the wheel and torque the lug nuts in a crisscross pattern to the specified torque.
Lower the vehicle and pump the brake pedal several times to seat the pads.
Test drive the vehicle to ensure the shaking issue is resolved.
