So I'm seeing something on my '06 Grand Prix that has me a little lost. I figured someone here has seen the issue, and can give me a little guidance. When I'm driving slow (5-15 mph), there is an odd noise that I believe is coming from my brakes. The best way I know to describe it is like similar to a deep grinding type noise. This still isn't really an accurate description, but it is an abnormal sound. From the driver's seat it sounds as if it's coming from the front driver's wheel. The more telling item may be that when this happens, the brake pedal pushes back at you and has a bad vibration. When it's happening, you don't have good brakes, but you can press through it and the brakes are there. I've noticed in parking lots and on driveways, both smooth and rough, but it may happen more often on rough surfaces with holes and such. When it happens, it does it for approximately 2-5 seconds then goes away. It will do it with or without you applying the brakes. I've had the pads changed about a year ago, and I had someone check the pads and rotors the other day with my oil change. He said all that looks good. It started as an occasional problem, but it is doing it more often. Does anyone have any ideas as to what may be going on?
