Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Use wheel chocks to secure the vehicle.

2. Remove Wheel

Sub-steps:
- Loosen lug nuts with a socket wrench but do not remove them completely.
- Lift the vehicle using a jack and secure it on jack stands.
- Remove the lug nuts and take off the wheel.
Tools Required: Socket set, jack, jack stands.

3. Inspect and Replace Brake Components

Sub-steps:
- Remove the brake caliper by unbolting it and hanging it with a bungee cord (do not let it dangle by the brake line).
- Remove the brake pads and inspect them for uneven wear or damage.
- Check the rotor for warping using a runout gauge; replace if necessary.
- If the rotor is warped, remove it by unbolting the rotor from the hub.
- Install new rotors (if needed) and new brake pads, ensuring they are properly seated.
- Reattach the brake caliper and torque the bolts to the manufacturer’s specifications (typically around 25-30 Nm).
Tools Required: Torque wrench, brake cleaner, bungee cord.

4. Reinstall Wheel and Lower Vehicle

Sub-steps:
- Place the wheel back on the hub and hand-tighten the lug nuts.
- Lower the vehicle from jack stands and remove the jack.
- Torque the lug nuts to the manufacturer's specifications (typically around 100-120 Nm).
Tools Required: Torque wrench, jack, jack stands.

5. Test Drive

Sub-steps:
- Conduct a test drive to ensure the shaking has been resolved.
- Monitor braking performance and listen for any unusual noises.
Safety Warnings: Ensure all tools are removed from the vehicle before starting the test drive.
