Somewhere in the process of a complete rebuild of my old car I swapped Master cyls, put an offset adapter/spacer on it etc...along with a retainer/catch, the pushrod will likely need lengthening. On the bench mock-up, I've added a short length of tube to the rod's end to 'compensate' for the added stack-up. While it seems to hit a point of resistance, there still is mechanical travel left in the master. HOW DO I SET THE PUSHROD LENGTH FOR PROPER TRAVEL? Thanks in advance!
