on my 85 I had to replace the booster unit I think the back half behind the master cylinder?! Before this the brakes were really good. So I replaced the booster and replaced the one line to the gear box and got a new tee and replaced the rubber lines.. Start the car and the brakes feel fine but as I start to drive the brakes slowly start locking up on me intil the car won't move!! Let the car sit and the brakes release and I can drive again..

I didn't remove the master cylinder lines just unbolted the 2 bolts to the booster and moved it to the side! Do I have to bleed the brakes or something?
I can only drive the car for like 5 min and the brakes freeze right the the rotor!
