I am in the process of finishing installation of new brakes on a car and the front brakes are not releasing and drag when the car is driven. I disconnected and plugged off the front brake line at the master cylinder and the front brakes finally released while the rear brakes worked as they should. I can't tell what is causing the front brakes to retain pressure. The brake master is a DeTomaso reproduction. The pushrod between the booster and the brake master is adjusted to minimum length. Both sides are dragging up front. I can swap in the same master from another Pantera. That car's brakes work well. Before swapping out the master can any you of think of other things to check? Your insight on this problem is appreciated.
