问：卡住刹车卡钳

尽管有可能崩溃（内部和“不可见”）橡胶制动线会导致缩回失败，但到目前为止，最常见的情况是卡钳正在粘住。如果卡钳在它们上的70,000英里以上，则本质上没有重新建造它们是不可重复使用的。卡尺孔中有一个内密封，操作条件极为严峻​​，包括连续腐蚀和极端热量。

I have learned the hard way that the only way to have any reasonable assurance that disc brakes will work properly, if they are present as "worn out’, is to automatically discard the calipers and torque plates and buy loaded re-built calipers from a reputable vendor such as AC Delco or better yet, through an OEM dealer rebuild source. You may also have sticky sliding bushings in the torque plate, accounting for the stickiness you are seeing so you can check that out as well. But, again, if you have north of 70,000 miles on the calipers, just trade them in and save yourself a lot of headaches and unusual wear patterns on your brand news pads and rotors.
