一辆奥迪五缸轿车,制动过程中刚踩下制动踏板和将制动踏板踩到底时出现发抖现象。经检查,制动液不少,后又对油路进行清洗、放气,故障来得到排除。该车采用液压制动和转向为一体的液压加力器,经试车,制动性能良好,而且不跑偏。根据上述故障现象分析,此故障与制动轮缸无关,问题可能出在制动主缸、增压器和液压加力器上。后又分析,如果制动主缸有故障,各轮缸应工作不正常,出现制动失效和跑偏。如果制动主缸没有问题,那么增压器
An Audi five-cylinder sedan, the braking process just press the brake pedal and the brake pedal in the end tremor. After examination, a lot of brake fluid, and then clean the oil, deflated, trouble to be ruled out. The car uses hydraulic brake and steering as one of the hydraulic booster, the test car, braking performance is good, and not deviation. According to the above symptom analysis, this fault has nothing to do with the wheel cylinder, the problem may be in the master cylinder, supercharger and hydraulic booster. Later analysis, if the master cylinder brake failure, each wheel cylinder should work abnormally, there brake failure and deviation. If there is no problem with the master cylinder, then the supercharger
