Guys I am stumped an need some help. I have a 39 coupe, GM front calipers, GM rear drum. M/C under the floor and 2# front residual valve and 10# rear residual valve. Everything in the system is new and brakes are bled.

When I apply the brakes, everything works front and rear. When I left off on the brakes, the front calipers wont retract but the rears do. What could be wrong? I know my lines are correct from my MC and the plunger rod comes all the way back after the pedal is released. The front calipers are around the same level as the MC. I am wondering if the front 2# valve is the problem. Maybe it wont let the pressure come back?
