我还是amazon上拿算了。

看LT要不

刹车过软，第一反应肯定是刹车管道里有很多气泡。不过你这都换了刹车油bleed了，应该是排除这个原因了。 看这里，http://mechanics_stackexchange_com/questions/7819/brake-pedal-goes-all-the-way-to-floor-after-abs-was-activated 确实有可能是ABS isolation valves 的问题。不过看他们的说法，这个valve有些车应该是可以单独换的。

This is an answer to a variation of the problem:

When ABS activates, the brake pedal goes to the floor but returns to normal height unless ABS is activated again.

This applies to a Saturn S-series (SC, SW, SL) and may apply to other makes and models as well.

The ABS system uses a series of solenoids and valves to redirect fluid flow. A set of valves (solenoid valves/isolation valves) are responsible for isolating the brake pedal from the rest of the brake system during an ABS event. If the ABS unit activates but does NOT isolate the brake pedal, the brake fluid will flow directly into the the accumulator, a spring-loaded brake fluid container for ABS systems. This lets the pedal sink to the floor.

If the brake pedal sinks to the floor only when the ABS unit activates, then your isolation valves may be the problem.
•You may need to replace the isolation valves (which, on my model, can be removed by removing two torx screws and pulling out the valve, which can be done in about 30 seconds and are easily accessible on the top of the ABS module)
•It is possible that the wiring between the isolation valve and the ABS controller is faulty.
•It is possible that the ABS controller itself is faulty.
•Finally, it may be that the o-rings that isolate the bottom inlet and the top outlet ports on the isolation valve have stretched or deteriorated. This would allow fluid to flow past the valve's body regardless of its open or closed state. Simply replacing these o-rings could solve the problem.

In my case, two new o-rings completely fixed the problem. This, after replacing the solenoid isolation valves and the ABS control unit, which turned out not to be faulty after all. (Note: the ABS system showed no errors or lights. The sinking pedal was the only symptom)

typical xiteker...下毒不留余力...

我昨天发给大胖LV的介绍,他回了,第一居然看懂中文了. 第二说:"unfortunately I don't have a couple thousand dollars laying around."

我就猜到LV肯定码了很多字死活发不出来

我现在就纠结要不要24-120/4这样的头。旅游，滑雪LX7用的很爽，现在别人看片也都是在手机上看，能不能清晰数毛没人关心的

第三期了啊。

这两天家里的小破马自达又抽疯了， 刹车时遇到路面颠簸（估计ABS启动了）后刹车突然变软，踏板沉底，以前也发生过一两次，但没这次么严重，这次害得我停红灯时直接停在路口当中了，而且以前是很快就会自行恢复，而这次在一天后也没完全恢复，刹车就这么一直软下去了。 以前在小车行检查过，说最大可能是ABS隔离阀出问题（马自达的通病），要换整个ABS模块，换了后还得重设电脑，所以就送去马自达敌了那让他们检查一下，结果敌了告诉我说是需要换刹车油（10万公里了）和Bleeding、换前后刹车碟片，价格相当感人，于是只让他们换了刹车油，自己回家换了刹车片，刹车仍然这么软。看来真是ABS模块里的隔离阀的问题了？

确定?   四驱的还不见得都是全时四驱而且就算全时四驱也还能撑撑，前驱或者前驱为主的四驱车拖后轮太坑人了。 图上这个皮卡因为后驱拖后轮还是比较合理。 本帖最后由 LongVoyage 于 2016-9-9 13:39 编辑
