Half ton power drum brakes? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hiya! My 1967 has the factory all-wheel drum set up (and manual of course). I was just wondering, could I add a power booster from a power disc brake truck and stick it behind the master cylinder of a drum brake truck?

I know you're probably thinking, why would you do something like that? Just go disc brakes! Well, I'm not ready for the entire swap yet ($$$!) but I have a booster lying around along with the correct bracket. Just curious, I might go through with it if you folks think it'll work.

do it..you won't even need disc brakes then,,

it's a direct fit.

you just need the rod from the pedal and the booster..your master will bolt right on

and a vacuum line ran to the intake

I ran a disc booster with front drums on my 68. It worked great sometimes. The booster had a diaphragm leak, so I had some issues, but it was due to faulty parts.

Here's a link to the post with pics on a 69 that I did this to.
