Most bicycle brake systems consist of three main components: a mechanism for the rider to apply the brakes, such as brake levers or pedals; a mechanism for transmitting that signal, such as Bowden cables, hydraulic hoses, rods, or the bicycle chain; and the brake mechanism itself, a caliper or drum, to press two or more surfaces together in ...
The chain brake remained in use until the 1870s in America [9] and 1890s in the UK. [10] The Heberlein brake is a notable variation on the chain brake popular in Germany, using an overhead cable instead of an underlinked chain. Hydraulic brakes. Actuating pressure to apply brakes was transmitted hydraulically (as with automobile brakes).

A band brake fitted to an 1873 steam locomotive of the Rigi Railways. A band brake is a primary or secondary brake, consisting of a band of friction material that tightens concentrically around a cylindrical piece of equipment or train wheel to either prevent it from rotating (a static or "holding" brake), or to slow it (a dynamic brake).
When the brake pedal of a modern vehicle with hydraulic brakes is pushed against the master cylinder, ultimately a piston pushes the brake pad against the brake disc which slows the wheel down. On the brake drum it is similar as the cylinder pushes the brake shoes against the drum which also slows the wheel down.
The brake pad and disc (now both having the friction material), then "stick" to each other, providing the friction that stops the vehicle. In disc brakes, there are usually two brake pads per disc rotor, they both function together. These are held in place and actuated by a caliper affixed to the wheel hub or suspension upright. Racing calipers ...
Douglas motorcycles were available with Research Association disc brakes front and rear on their 1923 RA model, sometimes called TT model, with Freddie Dixon's 1923 sidecar TT-winning machine of that type also having a passenger-operated disc brake for the sidecar wheel. [5] [6] Drum brakes were first used on motorcycles in the 1920s and the ...
Bicycle chains Roller chain and sprocket. A bicycle chain is a roller chain that transfers power from the pedals to the drive-wheel of a bicycle, thus propelling it.Most bicycle chains are made from plain carbon or alloy steel, but some are nickel-plated to prevent rust, or simply for aesthetics.
