Disclosed is a road surface braking system for an automobile which is totally different in conception and structure from the prior art. The braking system includes a hydraulic source, an on/off hydraulic source operating switch which puts the source into an operative state or a non-operative state, a piston device connected to the source such that it can be operated to be extended and withdrawn in response to the amount of force applied from the source and can be driven by the source, and a road surface braking member connected to the piston device such that it can be contacted and separated from the road by the piston device and can be driven by the piston device. Also, the braking system further includes a switch controlling device for controlling the on/off hydraulic source operating switch so that the hydraulic source can be operated only under certain predetermined conditions.
