well guys, the stupid guys at sunridge nissan screwed me again. I had this annoying brake problem after I slid into a curb a while ago. Everything was supposed to be fixed, but my brake made this "whoop whoop" sound when I hit the brake. I took it to nissan and they told me it was a glazing problem and that it was common on all sentras. fine. they remachine my rotor. It happens like a week later, so I bring it in again. They tell me know that it is no longer under warranty so I pay them like $50 to remachine the rotor again, cuz they say this is the problem. " It won't happen again" they tell me. And what happens, a few hours later, the same thing. I don't think those A- holes know what the hell is going on. Can someone tell me what might be wrong?? I am sick of the dealership!
