Re: Dual Master Cylinder

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.
