My alero drifts to the right when I start to brake, no matter how fast or slow I'm going. I have to turn the steering wheel roughly 30 degrees left to counter the front end shifting. Then the steering wheel stays in the position until I release the brake, then it re adjusts itself. Also when I get off the brake it makes a noise under the floor on the driver side. It drove fine when I bought it, but the trac off light comes on and the service engin soon light. I've had the car a month and put about 200 miles on it. Any suggestions?
