Master Cyl. Need to I.D. this one

[Mr. Jones]

The owner of this truck bought it with this unit installed,he has no pedal.I went by this morn.and pumped the pedal and nothing,no fluid leaking on any wheel cylinders.I'm thinking about removing the top side sending unit then pump'em up just to see if it's moving any fluid at all.Don't know if the owner received any receipts or paperwork from the PO.....would be good to know what the application is for this one.Any info is good info....
Thanks,
Dan

According to the part number that is a 74 part number. Check the push rod length to see if it is pushing the plunger in.

f4ta is a 94 part number. 74 would be d4ta

Your right, it is 94 , sorry for the misdirection. I knew it was a 94 when I posted, don't know why I posted 74. What's the sense in being stupid if you can't show it once in awhile.

I believe that is a 1994 F150 booster M/C cardone p/n 54-74219. I think the red switch is where the cruise control disengage hooks up.

The mounting base on that booster is angled. Did he have to modify the hole in the firewall to make it work?
