Don't expect any great response to this. Yes, for safety reasons, several cars I know have dual master cylinders and vacuum boosters. Problem is, there is no engineered "kit" to do this. You might get a couple replies regarding "what I've done", but in the end, you are pretty much on your own to fabricate a mount for a common master cylinder (selected by mounting adaptability) and roughly the comparable weight and brake system that master cylinder approximately supported.

The greatest contribution to braking safety you can make is to completely re-tube your car making certain the tubes are routed and fastened down neatly. In way more than 30 years of screwing around with old cars I have never seen a brake tube fail except from corrosion, usually external as a result of road salt. Do you drive on salted roads? New tubes and flushing the fluid every few years will give you reliability.

The problem I have seen with several cars retrofitted with dual master cylinders is that the push rod does not have enough stroke to activate both chambers fully. I can tell that when I am bleeding brakes and opening any one bleeder screw allows the pedal to go to the floor. It is a fools paradise in that case.

So if you install a dual, make sure you engineer it correctly to achieve full stroke of both pistons otherwise you have gained nothing.
