power brakes

Has anyone converted to power brakes by adding booster and dual master cylinder with stock drums. 1966 Fury III.

It's not challenging - one should swap out the pedal assembly too because the leverage ratio for a manual pedal assembly is much greater, however I have heard that it's just fine using a manual pedal with a booster.

I have no personal experience with the retrofit, but everything if sourced correctly will simply bolt up.

Thanks, would you think aftermarket or salvage yard source.

The correct booster would be a Midland Ross unit. That is the one with the lock ring around the outside. If your salvage yard has one, grab the mounting plate and the pedal while you are at it. You can use the '67 master cylinder which will bolt on the '66 mount plate. You will also need to source the '67 distribution block and fabricate the brake lines from the master cylinder to the distribution block. You would also want to have the salvage yard booster rebuilt.

X 2 on what Davea ^^^ indicated ^^^ —- all of that has to be salvage yard ONLY —-
Because the ONLY thing on that list that is available N E W is the Dual Master Cylinder…..

Stephens Performance has a Mopar salvage yard in Alabama...you may be able to source what you need there

The back plate and pedal assembly are different...here you can see the 4 holes where the booster bolts on

Correct - I neglected to say that there is a backing plate that will be part of the swap - one should get that plate as well as the power brake pedal assembly.

I removed a Power brake booster, backing plate and underdash linkage from a 66 Chrysler Newport that I parted out and swapped it in my 65 Sport Fury. I bought a new dual bowl master for a 72 or newer C body drum brakes and made new lines myself. Easy Peasy. It has been working great for the past 20 years or more.
Note: I was able to test the booster before I removed it and it was working fine. If you cannot test it, you may want to have it rebuilt before installing it.
If you decide to upgrade to front disc's, you need to upgrade to a dual diaphragm booster since disc's require twice as much boost as do the drums.
