      for z brake i used the amplifier z drive ok output which switches off when the drive has faulted or is not enabled connected by a relay to the brake, so the brake is always on if the drive is off.
      hence if there is no power or the drive is off the brake is on.

I opted to replace the drives with viper v95's from larkencnc but I am just guessing as to what the motors are. The Y has been replaced with a 4 pole motor but the x and Z are still original 2 pole motors.
