我大队一台ZL40装载机在使用过程中发现,踩下制动踏板后明显地感到制动滞后,不能立即减速和停机。由于该机采用气顶油双管路钳盘制动,所以首先检查气路情况。 启动发动机后,发现气压表压力长时间不能达到规定值,经了解,气压表刚刚更换不久,这就排除了气压表读数不准确的可能,从而判断一定是气路存在故障。 During the using process, a brigade of ZL40 loader of our brigade found that the braking retardation apparently felt after depressing the brake pedal, which can not immediately decelerate and stop. As the machine uses gas cap dual-pipe caliper brake, so first check the gas situation. Start the engine and found that the pressure gauge pressure can not be achieved for a long time the value of the understanding that the barometer just replaced soon, which ruled out the possibility of barometer readings inaccurate, so as to determine the existence of gas path failure.
