I have a bit of a mystery on my hands. Last summer after I purchased my coach, I noticed that the brakes were a little spongy. I had them power bled, and they worked great for about a month until they started getting slightly spongy again. That was September.

I parked it for the winter and started up the engine and generator once or twice a month. But now, the brake pedal travels all the way to the floor, and there's very little braking power. The master cylinder still has brake fluid in it.

The brakes were rebuilt by the PO, and has newer stainless steel brake lines, proportion valve, master cylinder, 80mm front calipers, new wheel cylinders on the rears, and a vacuum pump.

So what would cause the brakes to do this, even though it wasn't driven during the winter?
