The vacuum brake is a braking system used on trains and introduced in the mid-1860s. A variant, the automatic vacuum brake system, became almost universal on British train equipment and in countries influenced by the British practice. Vacuum brakes also enjoyed a brief period of adoption in the United States, mainly on narrow gauge railways. Its limitations caused that it was replaced progressively by systems of compressed air that began in the United Kingdom from the seventies. The vacuum braking system is now obsolete; is not in use on a large scale anywhere in the world, except in South Africa, largely supplanted by air brakes.
Vacuum brakes are first used instead of the air brake on railroad locomotives. This braking system uses a vacuum pump to create vacuum in the brake line. The integral construction of the brake cylinder uses this vacuum reservoir for the application of brakes. Today most light vehicles are equipped with vacuum assisted hydraulic braking system where the vacuum is created from the engine which reduces the stress of the driver on the pedal. The vacuum braking system was modified above these reasons and tested the same for its implementation in both light and heavy vehicles. The operation of the system is somewhat similar to the air braking system. The main difference with the air brake system is that vacuum is used instead of compressed air. The design and modified system also include the vacuum brake system, ie the loss of vacuum will cause the brake to be applied due to the force of the spring.
