I have a 2006 Malibu when I come to a stop it shakes like maybe the ABS is not working right. I've replaced the brakes and rotor. When I first replaced the rotors the problems goes away. But after several miles (1000) it starts again. I replaced the rotors again with a bosh rotors, again the problem went away for a while. I replaced them again, but the problems coming back. The rotors are warrantied for life so that not a problem replacing them. The problem is very sever if I have to make an emergency stop and i'm afraid it wont stop one of these times
