Hydraulic braking system is comprised of a prefill valve, a energy accumlator, a foot valve, caliper disc brake, ( or other types of brakes), and the brake tail light switches, the presure switches. After filling the energy accumlator with the presure oil through the prfill valve, the presure oil directly goes into the foot valve. Actually the foot valve is a ratio reversing foot valve, the the prusure oil enters into the brake which is near the tyre. When the brakeage is not enough, the the energy accumlator supplies the oil..
There is another type, which is to brake with gas pushing liquid. The vacuum booster in the engine produces gas presure so as to push the brake oil cylinder, the oil in the brake oiler then enters into the brake oil cylinder, which is to increase the power, finally the oil enters the brake.
At present, the most brakes are disc brakes, not the drum brakes.

Hydraulic brake system consists of: filling valve, accumulator, foot valve, clamp disc brake (or other forms of brake) and rear brake switches, pressure switches and other components. Pressure oil through the oil charging valve to the accumulator, the way into the foot valve, foot valve is actually the ratio of a foot valve, and into the tire next to the brake. When the brake force when the short-term oil supply by accumulators.
There is also a form of gas to push the brake fluid. By the engine vacuum pressure booster pump gas produced to promote the brake cylinder, brake right into the brake cylinder oiler, played by the purpose of force, and then into the brakes.
Most brakes are disc brakes, instead of drum brakes.
