If you have the motor off and want to do limited testing on the bench to check for noisey operation and brake drag is to rig up a dc voltage to operate the brake by using a 120vac outlet with a 5amp rectifier in one lead and feed it to the two wires of the brake, Check the polarity of the brake voltage when on the machine and hook up with the same polarity just in case they have a reverse diode fitted on the motor.
Then see if the shaft turns free by hand. If every thing sounds and feels OK, hook up a car battery to the DC motor leads and it should run at around 50~100 rpm, reverse the leads for the opposite direction test. Obviously take care to ensure the 120v from the socket is well taped up or insulated. Rough running or excess current can usually be detected.
