95 K1500, been sitting, brake fluid res empty

[johnnyclack]

I am the original owner of this truck, it has 102K on it, majority of those miles are freeway miles acquired in it's first fours years of life. In the past fifteen years it has not seen 10K mi. I use it now mostly for camping and pulling a light weight fishing boat.

After sitting this winter I cleaned it up and check the fluids, the brake reservoir was empty (some fluid remaining), front & back. I poured in some BK fluid and pumped the brakes, no question the system needs to be bled which I have yet to do. When I attempt to move truck the brakes are hanging up and not fully releasing.

Tomorrow I plan to pull the wheels and check out the system. Any bets as to what I might find... look for ?

Thx
