I just had my tow truck Master Cylinder fail while pulling into the garage and I want to replace it with a Dual-Circuit type.

So the question is, have any of you upgraded your single pot MC to a Dual-Circuit MC and then connected a Hydrovac to each circuit? I'm told this should work and that some British cars were made that way.

My truck has the 1-1/2" bore MC and the largest Dual-Circuit MC I have found is 1-5/16" bore (1970's Chevy 1-ton). Any reason why this won't work?

Thanks,

Mike B smile
