no I'm hooked straight up to the transbrake. through a 2 step I had posted this problem last summer when I first had the car out and started using the brake and thats when it would not release it would set there for a second then it would release, so after a lot of help from you all I rewired the whole thing bought a new switch and solenoids it would still hang some times. so I went ahead and put a heavier spring on the reverse valve and the last race of the season it never hung up it seemed to work perfect, but I did not put a real strong spring in it because some said it would burn up my solenoid, But my son inlaws new Trans has a very strong spring in it. it is hard to push in compared to mine. mine still works. I was just wandering if anyone may know what the normal Poundage of sping it should be. alot of the trans shops around here don't give out free info. and are very hard to talk to. they all want you to bring it in. It is a Pro Brake
Thanks Andy
