This page is intended to point out the advantages of different types of bicycle brakes, and so link to separate articles on servicing them. Not all of the articles have been written yet, but there is good coverage here of rim brakes, cables and coaster brakes.
Also see the table of contents page covering articles about brakes.
Felgenbremse, Rücktrittbremse oder Nabenbremse
A bicycle brake may work at the rim, or at the hub. Rim brakes have the advantages of light weight, of large heat-dissipating area, and of placing low stress on the bicycle frame, fork and wheel -- though heat dissipation is limited by risk to the tire.
Hub brakes have the advantage of weatherproofness and of not being affected by rim dents or wheel true. Because heat-dissipating area is smaller than with rim brakes, these brakes run hot -- but some are designed to.
All bicycle brakes are operated by hand levers by way of cables, or sometimes hydraulic lines -- except for the coaster brake, one type of rear hub brake, called in British English a "backpedaling brake" or "foot brake". In American English, it is called a "coaster brake", an expression which dates back to the its introduction in the late 19th century -- it was novel in providing a brake while also allowing coasting, as an alternative to the fixed gear.
This site includes extensive information on rim brakes, describing the different types and how to adjust and maintain them.
There is also a page about cables on this site. Poor brake performance often results from cable problems.
This site has ample information on coaster brakes including exploded drawings of a number of different models -- see links at the bottom of the main coaster-brake page. Many internal-gear hubs include coaster brakes, drum and disk brakes. Maintenance of these is covered on the pages about the internal-gear hubs. Many drum and disk brakes are the same as others supplied on hubs without gears.
Except for the page about tandem brakes, other information on drum brakes, disc brakes, and on hydraulic control is still scanty, but please note the warning about the tendency of a front disc brake to extract the front wheel from the fork. Also note that most cable-operated disc brakes, and direct-pull brakes (one kind of rim brake, also called V brakes) require special brake levers, mostly available for flat handlebars. About these brake levers, please see Tom Deakins's page about handlebars.
Montiere immer zwei Bremsen!
With only a couple of exceptions, every bicycle should be equipped with two brakes. Any brake will fail sooner or later, and then you really need the other one! The exceptions are:
- fixed-gear road bicycles. These can get by with only a front brake because the rear wheel can be slowed by pushing back against the turning pedals
- track racing bicycles, which are also fixed-gear bicycles, because these are the only traffic on the track, and abrupt stops would be hazardous
- tandems and other bicycles which carry a heavy load. These generally should have three brakes -- powerful front and rear rim brakes for stops, and a drum or disk brake capable of heavy heat dissipation to control speed on descents. See the page on tandem brakes.
