Wheel cylinder issue - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Got one I've never seen before - on my '70 C10 SWB step side, both front wheel cylinders are locked fully extended. They are both clean, no rust no leaks. I have not tried to press the pins back in until I get some information if this is a common issue. Should I just bit the bullet and replace both or could it have something to do with the master cylinder?

Also, the bleed nipple on the front front wheel cylinders are directly against the backing plate - does this look right? I can't get my brake line wrench on to them to open. Could the wrong wheel cylinder have been installed at some point?
