Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the battery for safety (if necessary).

2. Remove Wheel

Use a lug wrench to loosen the lug nuts.
Raise the vehicle using a jack and secure it with jack stands.
Fully remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Components

A. Inspect Brake Rotors

Check for warping by using a dial indicator or runout gauge.
If warped beyond specifications (usually more than 0.002 inches), replace the rotors.
If the rotors are in good condition, consider resurfacing them if applicable.

B. Check Brake Pads

Measure the thickness of the brake pads; replace if below manufacturer's specifications (typically less than 3 mm).
Ensure pads are wearing evenly; replace if uneven.

C. Inspect Brake Calipers

Check for any sticking or binding calipers; replace if necessary.
Ensure caliper slides are lubricated and functioning properly.

4. Reassemble Components

Reinstall the brake pads and calipers.
Put the wheel back on and hand-tighten the lug nuts.
Lower the vehicle and tighten the lug nuts to the manufacturer's torque specifications (typically around 80-100 ft-lbs).

5. Test Drive

Reconnect the battery (if disconnected).
Test drive the vehicle to ensure the shaking has been resolved and the brakes are functioning properly.
