Even Brake air compressor doesn't.

Getting things ready for Turkey Day, brought the Bounder out to the street. Hooked up the Durango and started hooking up the Even Brake, started the self-test and, silence.

The actuator tried to press the brake pedal but with no air pressure it was less than effective. The effort was appreciated but, none the less.

Anybody have this or a similar issue? What was the fix?

Thanks.
