94 f350 brakes question

Is there a pump or something that creates vacuum for these brakes?

I know how the master and booster work but is there something else?

I do believe that the OBS trucks booster worked off vacuum that would be supplied by a vacuum pump. But don't take my word for it.

you are right im mix and matching my trucks here. On my truck because the cummins motor doesnt have a vacuum pump, I added a bendix vacuum pump. If I want to get rid of it what would I have to do? Swap brake boosters with something else?

there is a vac, pump on the driver side under the a/c comp.
if the brakes fell like they grab and then let go and repeat then it is prob. the vac. pump. and if the pump is makes a weird noise then its bad. pull the vac. line to the brake booster and see if there is suction. post back if you have more ?s
