Abstract

A hydraulic unit for wheel slip control, which is located between a master cylinder and wheel brake cylinders. Reflection damping devices are installed in main brake lines located between the hydraulic unit and the master cylinder which damp pressure waves that originate at control valves of the hydraulic unit. When the control valves are triggered in the wheel slip control mode the pressure waves are largely kept away from the master cylinder. By the means of length adaptation of the main brake lines, the brake lines can also contribute to the damping.
