Are going to bleed? …brakes that is…

Bleeding Brakes.
(1) Remove cap screw from bleeder connection, and thread bleeder drain hose into this opening. Allow bleeder hose to hang in a clean container.
(2) Care must be taken not to drain the master cylinder reservoir during this operation; otherwise, air will enter and make rebleeding necessary. The reservoir must be full during the bleeding operation.
(3) Loosen bleeder screw one full turn, and depress the brake pedal slowly; then, allow the pedal to return to the “OFF” position. Repeat this operation approximately 10 times, to provide a pumping action to force fluid through the line, and expel all air. This operation must be repeated at all four wheels to bleed the entire system.
(4) Watch flow from bleeder hose, keeping hose submerged in fluid in the container. When air bubbles cease to appear, or when the stream is a clean, solid mass, close bleeder connection.CAUTION: Fluid withdrawn during the bleeding operation should not be used again.
It’s a good idea to get the manual that goes with the WW2 in order to understand how it works or should work.   You can get a copy of The Complete WW2 Military Jeep Manual (Brookland Military Vehicles) from
