Power Brake Booster

Is this the booster we get w/ any of the power brake conversion kits from the vendors? Sure looks like the one I got.

Thier fitment test says it fits a 1977 Ford Bronco.

That's a reproduction of the OE booster in '76-'77s. Some vendors sell a GM type. I like the OE duel diaphragm smaller diameter for better fitment.

Thanks jckkys!

If you go with the stock eb booster it takes inner fender modification to fit on a non 76-77. I think early on bc was selling theirs with a mustang 2 booster to clear the fender. Now the no fender mod kits use the gm style.

Thanks Steve, it already had that "mod"

. So yesterday I replaced my old booster with the one in my OP. They were identical.
When I got my old conversion kit some 15 years ago, I wasn't really impressed. It gave some power assist, and I just
thought, well that's how these small boosters work. So I got the new one installed and holy crap! Waaaaaaay more
power assist! I have actual "power brakes" now!
Funny thing is, Napa had only one distribution center in the whole U.S. that had this booster in stock. And it was the DC in my area.

EDIT: speed bleeders are awesome! Pricey, but well worth it.

Of all the vac booster options, does the stock booster give the most assist or would I be better off grabbing a vendor replacement? My '77's booster is in need of replacement.

Maybe look into Hydroboost WheelHorse.
