Abstract
A hydraulic brake for bicycles consisting essentially of a brake lever fastened on the steering column of a bicycle which works on a master piston movably arranged in a master cylinder, wherein the chamber in the cylinder is filled with hydraulic fluid, which is conducted by way of a hydraulic tube into the chamber of a working cylinder, in which a main piston is movably arranged, which works on the brake shoes of the bicycle. Along with lower manufacturing costs, there is easy interchangeability and a good reliability in servicing the brake. A single working cylinder is fastened above the fork of the bicycle and the main piston is connected with a control head, over which a traction cable is directed, which works on the usual brake shoes.
