I use this slack adjuster was not good, so how to fix the car, so I’ll put down, I told the boss said this thing, the boss said no way, now factory. There is no proper slack adjuster, the new slack adjuster has bought, but may will be two days before they sent, I can only to shut down, although slack adjuster but the car models can’t use, forced to repair it probably what things, so I think it is the first stop, there are a lot of slack adjuster in our factory, but also do not know what just do not have the slack adjuster, so I have no way to repair the car.
