The invention, a vehicle anti-theft device, is in response to the increasing number of vehicle thefts. The device is for immobilizing a vehicle in preventing theft and/or unauthorized movement of the vehicle, whether the vehicle is running and left attended, or locked and secured. The anti-theft device is a hydraulic system connected to the brake lines, between the master brake cylinder and the wheel brake cylinders. By maintaining brake fluid to one-way flow from the master brake cylinder to the brake calipers, will prevent the wheels from rotation. The device engages a camshaft, placed within the devices' encasing, by the turn of a key lock rotary action. The key lock is connected to the camshaft, and the rotation of the key lock equally rotates the camshaft. The rotation of the camshaft operates the device between an engaged and disengaged position. In a disengaged position, the brakes are free to function as they would typically. In an engaged position, the device is not activated until the wheel brake pedal is applied. The application of the wheel brake pedal transfers the hydraulic pressure in the brake lines, this increase of pressure locks the wheel brake calipers. The engaged camshaft permits brake fluid to flow, increasing pressure, from the master cylinder to the wheel brake calipers, but the camshaft inhibits fluid flow in the opposite direction. Under this condition, pressure is maintained between the wheel brake cylinders and the activated device. The wheel brake calipers are locked and the vehicle cannot be moved by driving, or by lifting one-end of the vehicle by a tow truck without sustaining damage, until such time that the device is disengaged
