Abstract
In a known motorcycle brake system, the pedal-actuated master cylinder acts on the front-wheel brake and the rear-wheel brake and the hand-actuated master cylinder acts on the front-wheel brake. The brake force regulator's control behavior provided by a stepped control piston is influenced by the hand-actuated master cylinder. This known system has functional disadvantages since the rear-wheel brake is evacuated of fluid by movement of the control piston if the hand-actuated master cylinder is actuated alone. In addition, the regulator's change-over point is reached at a relatively high pressure. These disadvantages are eliminated in the present invention by the provision of a valve adapted to close independently of the position of the stepped piston which is prevented from moving when the hand-actuated master cylinder is actuated alone by a stop against which the stepped piston abuts.
