Good night, if someone can help me. For some time my car, a Daewoo Lanos 1999 1.6, has been giving me problems as follows. First I braked to stumble, I thought that the discs were bent, change the new discs and pills and remained the same, then I have changed the rolls and the front booths and it remains the same is to say that when lifting the front rubbers with a cat and turn them, they go from side to side as if the discs were bent, but I no longer know what to be born, I have changed almost everything only left to change the box. I don't know what to do, please if someone can help me, I appreciate it.
