Well.. turns out both rear wheel cylinders were leaking inside the boot... and I couldn't see it until we pulled it open. Also, rear shoes are toast (body shop used my e-brake, seized it, and didn't tell me, so they over heated and cracked), front rotor is toast, gonna need to replace those... but not right away.
The cylinders were done at the shop, along with a new brake line in the back. I opted to change the shoes myself.... but parts availability was an issue here... and next day order was gonna be a reality (needed it done today due to scheduling issues), so Lee offered to pick them up at a local parts store, drive a half hour to get here, and install them with me for the cost of some fuel + the part! I'm looking at around $35.00 for the Wagner OE shoes, and I offered to pay him $20.00 for his time (more than he asked for).
He's on his way as I type this, to help me do it. Also, the shop suggested I get a set of High End Stainless Rotors for the front, as I sometimes let the truck sit for a week at a time, which is the cause of my front brake issues in the first place, and the SS set won't rust. He told me to wait til they go on sale at the local part store, and get them then.
All in all.... should run me $200.00 today.... plus whatever it costs me to do the front......
