1-Ton Master Cylinder Reservoir Losing Fluid - The 1947 - Present Chevrolet & GMC Truck Message Board Network

1986 C-3500 single cab dually w/hydroboost. Front discs, rear drums.

The pedal was a little soft today, so I opened the master cylinder. The fluid started to run out over the top of the back reservoir. (I assume that's for the front discs.) The front reservoir was nearly empty. It appears that fluid is being transferred from the rear brake reservoir to the front. Is that possible, or is the rear brake system simply leaking?

Thanks for your help, Les
