ABSTRACT:
A hand operated hydraulic bicycle brake includes a brake pad holding unit which is actuated by a rolling diaphragm. A flexible fluid line couples a master cylinder located on the handlebars of the bicycle to the rolling diaphragm which controls a slave cylinder located adjacent to the rim of the front wheel of the bicycle. Actuation of the slave cylinder forces the brake pad into contact with the rim, and further actuation of the master cylinder causes the unit to pivot to bring a second brake pad into contact with the wheel rim.
