进口五十铃柴油汽车制动系故障,可根据踏板感觉和变化程度以确定故障的部位,故障的原因和排除方法。一、踏板自由行程增大当踩第一脚踏板的自由行程正常(约25毫米),连踩几脚,自由行程逐渐增大时(此时踩油门不见车速提高),其原因系制动液脏,致使制动总泵补偿孔堵塞或制动总泵活塞皮碗扩胀等,使活塞回位慢,导致制动拖滞。如此应检修制动总泵,更换制动液或活塞皮碗。
Import Isuzu diesel vehicle braking system failure, according to pedal feel and degree of change to determine the location of the fault, the cause of the malfunction and troubleshooting. First, the pedal free travel increases When the first pedal on the free travel normally (about 25 mm), even a few feet, free travel gradually increased (at this time step on the accelerator but not speed), the reason is that braking Liquid dirty, resulting in brake master cylinder compensation hole plug or brake master cylinder piston bowl expansion, so that the piston back to slow, resulting in brake dragging. This should be overhaul brake master cylinder, brake fluid or replacement piston bowl.
