Oh well at least you found the problem :)
Yes brakes on motors tend to be that way as a fail safe, if power is lost for any reason the brake comes on.

That's a pretty cool feature wouldn't want the head of a machine to crush you incase of a power failure, thanks for your help getting the motor running, did some speed tests and torque tests, 3000rpm can't hardly hear it also the torque is insane compared to a stepper motor, looking to get the torque monitor output hooked upto an led bargraph maybe an LM391 driver  ;D

Yes, totally different league to steppers.
Steppers still have there place, they are on the coil winder I made and occasionally operate for a customer. It was simply because servos would not really have been any benefit although the whining racket (some say singing ::) )of the steppers sometimes makes me wish I had gone servos, thankfully it doesn't get used too much.
