A braking system for braking a motor vehicle by the front and rear brakes of the vehicle's front and rear wheels, respectively, including a distribution control device for controlling a distribution of front and rear wheel braking force produced by the respective front and rear brakes, according to a selected one of a first and a second distribution pattern, each of which represents the front and rear wheel braking forces in relation to each other wherein the rear wheel braking force defined by the second distribution pattern is larger than that defined by the first distribution pattern at least when the front and rear wheel braking forces are smaller than respective predetermined values. The selection of the two distribution patterns may be dependent on vehicle load.

[ What is claimed is:] [1.] A braking system for braking a motor vehicle by operation of a front and a rear brake for a front and a rear wheel of the vehicle, respectively, and for selectively effecting an anti-locking braking control to prevent said front and rear wheels from being locked during the operation of said front and rear brakes by monitoring rotating conditions of said front and rear wheels, said front and rear brakes including, respectively, a front and a rear wheel brake cylinder which are supplied with a pressurized working fluid, said braking system comprising:a distribution control device to control a distribution of a front wheel braking force and a rear wheel braking force which are produced by said front and rear brakes, respectively, and which are applied to said front and rear wheels, said distribution control device controlling said distribution according to a selected one of a first distribution pattern and a second distribution pattern, each of said first and second distribution patterns being a relationship between said front and rear wheel braking forces such that said rear wheel braking force defined by said second distribution pattern is larger than that defined by said first distribution pattern at least when the front and rear wheel braking forces are smaller than respective predetermined values, and when at least said rear wheel braking force is being increased,said distribution control device including a pressure reducing device for permitting front and rear wheel braking pressures of said fluid in said front and rear wheel brake cylinders to be substantially equal to each other when said anti-locking braking control is not effected, and reducing said front wheel braking pressure as compared with said rear wheel braking pressure when said anti-locking braking control is effected, whereby said first distribution pattern is established when said anti-locking braking control is not effected, and said second distribution pattern is established when said anti-locking braking control is effected.
