Solution

1. Preparation

Gather tools: jack, jack stands, lug wrench, torque wrench, run-out gauge, brake cleaner, and safety glasses.
Park the vehicle on a flat surface, engage the parking brake, and secure the wheels.

2. Lift the Vehicle

Use a jack to lift the front or rear of the vehicle as needed.
Secure the vehicle on jack stands for safety.

3. Remove Wheel

Use a lug wrench to loosen and remove the lug nuts.
Take off the wheel to access the brake components.

4. Inspect and Replace Brake Rotors

Inspect Rotors: Use a run-out gauge to measure rotor run-out. If it exceeds manufacturer specifications, replace the rotors.
Replace Rotors:
- Remove the caliper by unscrewing the caliper mounting bolts.
- Slide the caliper off the rotor and secure it with a bungee cord to avoid stress on the brake line.
- Remove the rotor by unscrewing any retaining screws or clips.
- Install the new rotor, ensuring it is seated correctly.

5. Inspect and Replace Brake Pads

Inspect Pads: Check the brake pads for uneven wear or thickness. Replace if necessary.
Replace Pads:
- Remove the old pads from the caliper bracket.
- Use brake cleaner to clean the caliper bracket and apply grease to the backing of the new pads.
- Install the new pads into the caliper bracket.

6. Reassemble and Test

Reinstall the caliper over the new pads and torque the caliper bolts to manufacturer specifications.
Reattach the wheel, hand-tighten the lug nuts, lower the vehicle, and then torque the lug nuts to the specified value (typically around 90-100 lb-ft for most vehicles).
Test drive the vehicle to ensure the shaking issue is resolved.
