I have a question about the hydraulic set-up on the B-24J models and I can't seem to find the answer.
Did the B-24J have a single hydraulic pump for the brakes on only one engine nacelle, or were there more as back-ups?
Also, if there was only one main pump, was there a back-up/aux pump for emergencies?
Thanks.
Jerry

I have a pilots flight operating instruction manual for B-24 D, E, G. In the emergency section it states that if the engine driven pump fails, turn on the emergency hydraulic valve. The electrically driven pump will furnish pressure for the brakes through the main system. If both pumps fail, build up braking pressure with the hand pump.
