Nissan Pathfinder Brake problem

Ok they can't work on it as much since they have full paying customers that come first. (I pay parts at shop cost and only 50% labor).

Seems the Anti-lock brake module or whatever it's called (the part they replaced) was faulty. When they unplug the anti-lock brake module, the brakes work fine.

So they are having a hard time tracking one down (last time they found a used one and it cost me $250).
