Do you mean that it doesn't have hydraulic brakes? :-) I expect that the

Hi
Hydraulic brakes don't amplify unless they use a booster. It is true that most drum brakes amplify when stopping
while
moving forward.
True but that's not a fluid system, it's a mechanical system.
Many cars of this time frame may not have a vacuum
advance.
Many?? I'm not buying it! Show me a stock car of that vintage that doesn't use
a vacuum advance. The only ones that I know of that were even close to that vintage that
don't have vacuum advances were the '64-'65 Chryslers with the 426 RACE Hemi
engine (the later street Hemis did have VA.)
I know my Fiat Spider doesn't( I think the VW's
did though ).
I've never had a spider but I had other Fiats and MANY VWs and they all had VA.
One of the common mods to the VW was to change the stock VA distributor to a mechanical
advance only distributor with a faster advance curve. I used that in a couple of VWs but
they weren't original.
Still, most any auto is just full of analog computing
elements.
You're right. Even you're only talking about non-fluid computing elements you
can include the numerous levers such as the brake pedal, shifters, parking brake handles,
brake cams, rocker arms, trottle pedal lever, trottle lever on the carburator, lots of
levers and cams in the carburator, etc etc.
