Which ones had hydraulic brakes?

Still trying to find info on the mystery 50's AS. Several folks have mentioned that some AS's had hydraulic brakes instead of electric. Can anyone list which models/years? Those are much more expensive to have installed at our local dealer so I'm trying to avoid buying a model with those. This is a TERRIFIC forum. Y'all are the best! Thanks for such quick helpful comments. God Bless!!!

I just removed the pneumatic/hydraulic activator from a 1978 Sovereign International that had had its disk brakes replaced with electric. Very interesting (and complex) mechanism. The service manual does quite a job explaining basic operation using vacuum from the tow vehicle and a standard electic controller line for the regulator solenoid. (anyone need parts?)

I think the electric brakes started to become most common in the mid sixties or so but that may not be a well founded impression.

Hi Bryan... thanks for the response. I'm actually investigating on a mid '50's Overlander or Cruiser. Wondered if any of those had hydraulics. Thanks and have fun!

That trailer you are looking at could very well have hydraulic brakes - need either you or the previous owner to look underneath and see if there are wires running to the brakes or a pipe/tubing line - if its tubing - its hydraulic. My 58 Overlander had both! One type on each axle - and it was original.
