In front brakes it is usual to hydraulic cylinders in order to equalize the pressures exerted by the shoes . 在前制动器中，通常使用两个液压缸，用以平衡制动蹄所产生的压力。
Loads are commonly applied with universal testing machines, hydraulic cylinders dead weights, or some form of pressure . 通常是用万能试验机、液压缸重物或某种形式的压力施加载荷。
Electrical signals are sent to the hydraulic valves by the microcomputer when a gear change is required by the powertrain control strategy . 当按照动力装置控制方案要求换挡时，电信号由微计算机送到液压阀。
