i just measured im only getting just over 3/4 inch of push from my piston on the master then im hard on the floor... Wilwoods have 1.10" stroke so im underdone..
Now how to increase the stroke ?? i cant lengthen the rod and the pedal is against the stop in 'rest position'..any ideas?
My bad........old brain errored again.....sorry. You'd think after using a lever and fulcrum a couple of times last week it would be elementary.

I just measured my travel and it's 3/4" also. I don't think travel length is the solution. I'll assume there needs to be a certain amount of reserve piston travel in the master for safety. The Right Stuff calipers would be my primary suspect. Based on forum observation there's a lot of people running the 7/8" Wilwood with stock pedals with no problems, though this is the first system I can recall (for what that's worth now) using the Right Stuff rear calipers. I do recall issues attempting to use another style of OEM parking brake caliper, possibly a metric?
