Technically, yes you can, but it is not recommended as the brakes become very sensitive and are easy to lock-up.
I had boosted drums on my old Galaxie and it took months to get used to and emergency braking situations always got interesing  :o
I also had boosted drums on my FC Wagon and they were only a little better control wise, but again easily locked in an emergency.

i also agree with them locking up very easy, but only with standard width tyres 175 or 185

a have a 59 fc with drum's all round and vac assisted and i wouldn't have it any other way, i have full control over my breaks from nothing to full lock,
under normal driving its very easy to drive but as with all cars when you stomp on them you will get them to lock up (abs exempt) and in the wet its even easier, but, i do have have 205/55/15 on front and 225/50/15 tyres rear, its a totally different story when the the 185 go on

I have removed my booster and re built all the cylinders  as i kept getting brake lock up.
Turned out someone over the years had put the primary and secondary shoes on the passenger side ass about im thinking a drivers side set was fitted to passenger side.

But i actually prefer the feel  thru the pedal now there certainly not discs but certainly not horrible.

VH 44 is correct - pipe from master cyl goes to inlet closest to the booster vaccuum, outlets at the front of the nose piece

I know the diaphragms are a bit tricky (and expensive) to get hold of but what about the VH24 ? Weren't they the original set up a la Nasco ?

Yes VH24 is Nasco booster for FE FC, but the unit itself is hard to find and parts for it are even harder to get

Hi,I have a VH24 on drums, works fine. National Brake Co in Shepparton, Vic. overhaul these units.  Price is not cheap, but you get great service at a lower price than quoted by some other repairers. Many repairers dont have kits, either. Housings on VH24 boosters are of alloy and can suffer from corrosions as well, so this can be a problem on repair.  Glenn

Good work Glenn, I knew there was a guy out there who did them but was unsure where. VH24 does work well on FC (It is designed for 4 wheel drum brakes)

Hydroboost in Melbourne can also rebuild /(possibly change over from memory) VH24's as well

Brilliant service and very knowledgeable!
