I know there has been a significant issue with the brakes on this car, I just wish I had done a little more research before I bought it November of last year. Roughly about 2 months and 8k miles after driving off the lot, I started to notice a pulsation on the front end. Shortly after, maybe 2 weeks, it got worse, as the steering wheel would shake during braking. I let it go for about another 2 or 3 weeks while I researched this issue. Once I joined this forum, I thought I solved the problem by taking the recommendations of several people on here to buy a drilled/slotted rotor to resolve the issue of the front brakes continually overheating and warping. So I purchased a set of the drilled/slotted rotors by Powerstop from AutoAnything.com, and installed them this past Monday night. This is not my first brake job, but I wouldnt consider myself an expert, either. Long story short, the day after install I noticed a slight vibration while applying the brakes at certain speeds. For instance, as I exited the freeway at about 70mph, no vibration until the car slowed down to around 50mph, then it would go away just to come back around 30mph, then go away again as I slowed nearly to a stop when it would reappear. I took the car to several shops, one shop finally coming to the conclusion that it was the rear brakes that were warped, since I just replaced the fronts it couldnt be them, right? Wrong, that didnt fix it, as it still occurs every time, around the same speeds. Now that I have driven it more, and the shop doesnt seem to know what the problem is, I have seemed to have developed a new problem. From time to time, as I approach a stop sign while driving slowly, just before I come to a complete stop, I will hear this horrible grinding noise seemingly coming from the front brakes. This doesn't happen every time, especially when I am on a test drive with a mechanic trying to explain the problem, and I cant get it to duplicate. I am extremely frustrated with this car, and the powerstop brakes( which neither they nor autoanything seem to have a resolution for). Anybody have any ideas to what might be causing these problems? SHould I tear it down and reinstall them? Turn the front rotors, return them?? Thanks
