These have two arms fitted to the frame or fork, pulled together by a cable strung between them. V-types have long arms and one cable which pulls across the top of the tyre. Cantilevers have shorter arms and a Y-shaped cable which pulls upwards. Both types are very powerful, and are found on mountain bikes and many others. Cantilevers have all but disappeared now in favour of the more powerful Linear pull brakes, but they are still commonly used on Cyclo-Cross bikes.
