ok, I'm thinking out loud here..so Matt or anyone else please let me know if my logic is wrong...
The master cylinder you are using is a tandem cylinder, correct?
Tandem styles are designed with two pistons in a common bore. They are suppose to be more safe than single piston because each piston feeds an axle, so if there happens to be a leak in the line to the front, the rear will still work properly because it is its own contained system.
Is it possible to plumb the system so that all of the fluid goes to the front axle only? This should eliminate part of the fluid demand on the master cylinder and therefore the pedal should not move as far as before.
If it does move just as far as before....the master cylinder is shot
If it moves less, but you still have to stand on the pedal to get the wheels hold...you need bigger power boost or a smaller bore master cylinder to increase the mechanical advantage.
The other option is to find ya a brake or hydraulic pressure gauge and plumb it inline. A leaky master cylinder shouldn't be able to generate or hold pressure for long.
Like I said, I'm just thinking out loud. Comments?
