Hello, I have what I hope is an easy brake question. My brakes are fine until the car has been running for an hour or so. Then, when I come to a quick stop or otherwise intermittently, the pedal goes to the floor. I repeat this is intermittent. I can still stop the car when this happens. Does this sound like air in the lines or a failing master cylinder? Any other ideas? Many thanks. Rob __________________________________________________ Do You Yahoo!?
