Solution

1. Preparation

Tools Required:
- Jack and jack stands
- Lug wrench
- Torque wrench
- Dial indicator
- Brake cleaner
- Replacement brake pads and rotors (if necessary)
Safety Warnings:
- Ensure the vehicle is on a flat surface and engage the parking brake before lifting.
- Wear safety goggles and gloves.

2. Remove Wheel

Loosen the lug nuts slightly while the vehicle is on the ground.
Lift the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Rotors

Inspect Rotors:
- Use a dial indicator to measure any warping in the rotors.
Replace if Necessary:
- Remove the caliper by unbolting it from the bracket (use the appropriate socket).
- Slide the caliper off the rotor and support it using a bungee cord or similar.
- Remove the old rotor by unbolting it from the hub (if bolted) or sliding it off.
- Clean the hub surface with brake cleaner to ensure proper fit for the new rotor.
- Install the new rotor and secure it with bolts.

4. Inspect and Replace Brake Pads

Remove the old brake pads from the caliper bracket.
Inspect the caliper slides and clean them if necessary.
Apply brake grease to the back of the new pads and install them into the caliper bracket.
Reattach the caliper over the new pads and torque the bolts to specification (usually around 25-35 ft-lbs).

5. Reinstall Wheel

Place the wheel back on the hub and hand-tighten the lug nuts.
Lower the vehicle off the jack stands and tighten the lug nuts to the specified torque (usually around 100-110 ft-lbs).

6. Test Drive

After repairs, conduct a test drive to ensure the shaking is resolved and the brakes function correctly.
