A hydraulic braking system capable of reducing the brake pedal stroke is provided by adding to the basic hydraulic braking system. The adding system is able to selectively execute the reduction of brake pedal stroke and, at the same time, capable of selectively adding anti-lock function and anti-slip function by including the changeover valves or opening and closing valves to the system. An auxiliary hydraulic pressure generator having a power hydraulic pressure source and regulator is interposed in the hydraulic conduit of at least one circuit, and an outlet port of the regulator is communicated to the wheel cylinders for connecting to the hydraulic conduit of the circuit. Brake pedal stroke can be reduced by inclusion of other conduit arrangements for adding the auxiliary hydraulic pressure generator and, at the same time, the changeover valve, anti-lock control changeover valve, and normally closed valve are selectively releasably added or mounted to the system, so that a brake system having short brake pedal stroke and sporty feeling can be obtained by low cost system ensuring desired braking operation. Additionally, anti-slip control for preventing the slipping of driving wheels can be added. |
