Can anyone help me identify what may be broken on my rx300? Here is what is happening. When I am turning the wheel and breaking to a stop (e.g. like pulling into a parking space) the breaks let out a sputtering sound the few seconds before I come to a stop. I can feel it in the pedal and it ONLY happens when the wheel is turned to a heavy degree (either way), and only when I am pressing down on the breaks to create a full stop. The sound is like a sputtering of air - almost like some pressure from a valve or something is being released. It makes the stopping feel less than certain although the car does stop. Thoughts?
