液压制动系统由：充液阀、蓄能器、脚踏阀、钳盘制动器（或其他形式的制动器）,以及制动尾灯开关,压力开关等组成.压力油经由充液阀向蓄能器供油后,一路进入脚踏阀,脚踏阀实际上为一个脚踩的比例换向阀,然后进入轮胎旁的制动器.当制动力不够时可由蓄能器短时供油.
还有一种是气推液形式的刹车.由发动机上的真空助力泵产生压力气体,推动刹车油缸,刹车油壶的右进入刹车油缸,起到增力的目的,然后进入制动器中.
目前大多数制动器为碟刹,而不是鼓刹.

答案

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.
