摘要

The hydraulic brake has master piston and by means of piston stroke of master piston, the path of brake shoes is specified. The movement of brake lever (3) takes place disproportional to movement of piston of master piston. The means is a cam disk/shaped disk (5), which is designed such that a larger stroke takes place at the beginning of the movement, and a finer, powerful stroke takes place at the end.
