front brakes locked up
ok so i had just rebuilt my master brake cyl and new ss brake lines all around. so the other day i was drivin back from the bank and i noticed my car had lost all power, finally figured out it was my brakes. stopped the car and smoke stared pouring out of my wheels.
so front brakes have the fluid going into them but the fluid is being caught there after a few pumps. it does not take much of any of the pedal to be pushed down for the brakes to work
so my question is could my check valve be in backwards or is it more of the passage ways being blocked in the master???!

What check valve are you refering to, the proportioning valve? That won't cause the fronts to stick/sieze. Sounds to me that with the new master, the calipers are getting better pressure than before and pushing the pistons in them to a point that they are sticking. If so, replace them.

It's also possible the master cylinder isn't fully retracting. If it's not pulling all the way back, it will block the compensating ports & you'll get behavior like this. Check the clearance into the master cylinder and the pushrod depth. Or, just retract the pushrod a turn or two & see if it clears up.

master is pulled. i can see where the piston is blocking the larger of the two holes on top where the res sits. closer to the firewall. would this be the problem?
