The earliest type of continuous brake was the chain brake [19] which used a chain, running the length of the train, to operate brakes on all vehicles simultaneously. The chain brake was soon superseded by air-operated or vacuum operated brakes. These brakes used hoses connecting all the wagons of a train, so the operator could apply or release ...
A vacuum brake cylinder and hydraulic master cylinder set was mounted on each bogie. From the master cylinder, hydraulic fluid passed through hoses to the operating cylinders. The operating cylinders actuated cam mechanisms within the brake drums to apply the internally expanding brake shoes to the inside circumference of the drums. The 20 inch ...
This standard specifies requirements for labeling and performance requirements for motor vehicle brake hoses, brake hose assemblies, and brake hose end fittings. The purpose of this standard is to reduce deaths and injuries occurring as a result of brake system failure from pressure or vacuum loss due to hose or hose assembly and plastic tubing ...

Since the ideal brake system would use only hard tubing for its lack of expansion, but some use of flexible hose is required, the ideal compromise is to use a hose type that allows a minimal rate of expansion. Thus the assertion that braided stainless steel hose is superior as compared to a typical rubber hose when used in a hydraulic brake system.
Powered by steam, it compresses air for operating the train air brake system. [3]: 2 The Westinghouse air brake system is used world-wide; [3]: 93 in Europe two systems that use the same principle are the Kunze-Knorr and Oerlikon systems. It can be a single-stage or, when larger capacity is needed, a two-stage cross-compound compressor.
