Abstract
In a known motorcycle brake system, the pedal master cylinder acts on the front-and rear-wheel brakes, and the hand master cylinder acts only on the front-wheel brake. The brake force regulator's control behavior is influenced by the hand master cylinder. This known arrangement has functional disadvantages, since the rear-wheel brake is evacuated of fluid if the hand master cylinder alone is actuated. In addition, the regulator's change-over point is reached at a relatively high pressure. These disadvantages are eliminated by the regulator of the present invention by the provision of a valve adapted to closed independently of the position of the regulator's stepped piston. The stepped piston is not moved when the hand master cylinder alone is actuated. Also, the regulator of the present invention provides an improved deceleration of the motorcycle.
