Brake pedal issue

[idastang]

Ok, I have searched through here to try to find an answer to my problem, so now I will just ask. My front disc will not fully retract when I let off the brake pedal unless I use my foot to raise the pedal. I am wondering if this is just a brake pedal return spring issue or something more? A little about the set up. It is a 69 4x4 with a 76 k5 d44 front axle. I have changed the master, changed all hard and soft lines, removed a drum/drum distribution blocked and installed a new disc/drum proportining valve, has new rear drums and had the drums turned and new calipers up front, and a new master cylinder. I tested the booster and everything is working except for the pedal returning to release the front brakes. And example is as follows; place the truck on a slight incline, press the brake pedal, put the truck in nuetral, remove my foot from the pedal and the truck just sits, now I take my foot and lift the break pedal and the truck will start to roll. Any help? Thanks

I have had this happen on a s 10 pick up that i just installed a new brake booster. The reman booster was not crimped right and would not release vacuum. Try to disconnect the vacuum source and try without. If it releases without the vacuum source replace the booster.

also look at the linkages on the back side of the booster. If it gets corroded it can bind

Thanks HayHauler, I tried your suggestion and it was spot on Thats the good part, the bad is I will now have to lay out about $100.00 for a reman at the local parts store. Thanks again to you and this site for a wealth of info!!!!!
