Juice brake problems

sounds right...do you see any sign at all of leakage??? When you speak of dual reservoir are you segregating your rear brakes from the fronts?? You may also need to install a proportioning valve. Not sure you need a dual reservoir on a car as light as a Model A.

It is my understanding that a dual reservoir allow 1 system to fail while leaving the other system intact. That is the only reason I am considering a dual reservoir.

You are correct. The dual reservoir is a fail safe system and I would not have hydraulic brakes without one. I have mechanical brakes on the Tudor and will not change them to hydraulic. Mostly because I want to keep it original and I basically don't drive that fast where it would make a big difference. Let's make no mistake about it. Hydraulic brakes are better stop faster and above all much safer. With the technology used on hydraulic brakes there is no comparison. Ceramic rotors are now employed in auto racing for their superior heat dissipation and elimination of rotors warping.

Mechanical vs Hydraulic....no comparison.

When I did the hydraulic conversion on my coupe, I installed a proportioning valve. After the first use the brakes locked up. come to find out, the new master cylinder has a built in proportioning valve and the two were working against each other. I removed the external proportioning valve and all was well. The supply house for the master cylinder told me that most new master cylinders have a built in proportioning valve. don't know if that is a fact or not, but something to consider when doing a hydraulic conversion.
