i had about an inch more pedal travel than i was happy with on my last conversion to discs.no amount of bleeding or adjustment helped but i did have good braking.
continued driving over the first few weeks brought the pedal up to a satisfactory position.
i suspect that with use,the pistons worked there way closer and retracted less but don't know for sure.
a pedal ratio of 1:6 with a 1" master,2" of pedal travel would not move a couple of 2.75" caliper pistons very far
