问：锁定制动器-2004凯迪拉克CTS
女友说，她突然开车沿着道路和汽车开车。不会超过40 mph。汽车闻起来很热。我检查了汽车，卡尺被锁在前驾驶员和后乘客上。我虽然有些怪异的机会，他们同时去了并取代了他们。试图流血时，他们再次锁定了卡钳。我认为这是欧洲央行，但我不确定。检查发动机灯已打开，但ABS却没有。不能带任何地方扫描并让某人出去扫描，这将花费约1/3的替代欧洲央行。关于其他可能导致该问题的建议，或者失败的制动模块是否可以锁定这样的轮胎？
我的汽车有170000英里。
My car has an automatic transmission.

Hi there. From the description you have provided, your vehicle’s left front and right rear caliper locking would have been a combination/proportioning valve before ABS (anti-lock brake system). The EBCM (electronic brake control module) controls the valves in the hydraulic modulator. It could be that the EBCM or hydraulic modulator is at fault.
It could also be卡住的制动器主缸检查阀if the modulator is designed for diagonal braking. Braking systems used to be controlled front to rear. The engineers incorporated diagonal braking to balance the braking system. Your vehicle’s检查引擎灯正在打开应该解决，尽管它不太可能与制动系统有关。应访问ABS计算机以帮助确定左前和右后卡尺锁定的原因。
I recommend having your vehicle’slocking brake calipersinspected and repaired by a certified technician, such as one from YourMechanic.
