While I agree 100% the single reservoir master cylinder can stop very well, in order to be much safer, you do need to upgrade. This is why the dual reservoir master cylinder was mandated.....in what? 67 I believe. If you have a failure anywhere in the system with a single reservoir master cylinder, you have two good pumps on the brake pedal at BEST and you're done. With the dual reservoir master cylinder, you will still have braking with a failure and can at least get the car stopped, so yes, the dual reservoir master cylinder is a huge upgrade in terms of safety. To say otherwise is simply untrue.

For what it's worth dept;I have 66 Signet 2 dr hardtp. 340/4spd built with BB torsion bars,Konis,sway bars,built for hard,fast road courses.Used to race in NH before New Hampshire International,on road course,half dozen corners,bowls,offset high speed crests,very challenging.I raced in modified due to 340 transplant, at speeds between 50 and 120 with Vettes.I used 4 wheel drums,single master cyl,only thing I did was drill holes through shoes (stop laughing)to relieve gas pressure build up.No matter how hard I pushed that 340 5k to 7k RPM.Never had brake fade,running 2 to 3 seconds behind hot Vetts.Point is...not talking trash against master upgrades had planned to do myself,but I am proof a properly adjusted and maintained system can and will surprise you favorably.
Thanks for listening,Signetroar
