I was wondering if any of you knew anything about the brake system on this car. The brakes lose pressure when you press and hold the pedal. It bottoms out, and the brake light comes on. This happens, yet the car leaks no brake fluid and the master cylinder appears to work normally. I was thinking the problem is the brake booster unit. Also, when I press the brake pedal with the engine off, I hear air escaping. I don't know if this is normal or not, but I thought I'd mention it. I would think that any brakes work on the same principles, but then again, I've never had to work on this type of thing. Any ideas?

Thanks,
Jon
