My brake pedal went all the way to the floor a few days ago coming down a hill, and ever since then, it has been really soft and spongy. The brake light was on continously for about a day afterwards, then went off. The brake fluid is right, neither high nor low, and the powermaster motor runs for about 6 seconds after starting the car, then stops like its supposed to. Then tonight, whenever I would first apply the brake to stop, I would hear a whining noise that sounded like power steering motor whine, but only when braking not turning. Fluids in brake and power steering resevoirs are good, and I don't appear to have any leaks. Any ideas or help would be appreciated. Thanks, Jeff
