brake problem

First off the corvette master cyl. was designed for a car with 4 piston 4 wheel disk brakes so it moves enough fluid for the willwood callipers but it is not a quick take up like the Chrysler unit so it needs all of its stroke to move the amount of fluid you will need to stop the car. Second you said the pushrod is not hitting the MC piston untill it is about 3" from the floor? If this correct that is your problem, make or buy a longer pushrod. I like to give the MC about 1/4" of freeplay so you don't cover up the compensating or return ports otherwise you will have pressure on the system at all times. Hope this helps and have a merry Christmas, Mike
