Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Loosen the lug nuts while the vehicle is still on the ground.

2. Raise the Vehicle

Use a hydraulic jack to lift the vehicle and secure it on jack stands.
Remove the lug nuts and take off the wheels.

3. Inspect and Replace Brake Rotors

Inspect for Warping:
- Use a dial indicator to measure rotor runout. If it exceeds manufacturer specs, replace the rotors.
Remove the Brake Caliper:
- Unbolt the caliper using a socket set.
- Support the caliper with a bungee cord to avoid stress on the brake line.
Remove the Rotor:
- Remove any retaining screws or clips.
- Slide the rotor off the hub.
Install New Rotor:
- Clean the hub surface and install the new rotor. Torque any retaining screws to manufacturer specifications.

4. Inspect and Replace Brake Pads

Remove Old Brake Pads:
- Remove the caliper bracket if necessary and take out the old pads.
Install New Brake Pads:
- Apply brake grease to the back of the pads and install them into the caliper bracket.
- Reattach the caliper over the new pads and bolt it back into place.

5. Reassemble and Lower the Vehicle

Reinstall the wheels and hand-tighten the lug nuts.
Lower the vehicle off the jack stands and use a torque wrench to tighten the lug nuts to the manufacturer's specifications.

6. Test the Brakes

Before driving, pump the brake pedal to ensure proper engagement.
Conduct a short test drive to confirm the shaking issue has been resolved.
