New master cylinder and booster from pirate jack, new lines and distribution blocks with hold off on distribution block to front brakes from inline tube, new rotors and calipers per the disco tech conversion. Brakes bled with motive products power bleeder. Nice hard pedal, but not activating brakes front or rear. Am I missing something like pushrods length between booster and master?  What should I look for next? Thanks in advance

if u have a hard pedal, sounds like ur pushrod is not even pressing against the master but bound up on something, make sure the rod is in the cup or if it even fits the new master. does it feel like a normal pedal or just rock hard not even moving the slightest bit?

pedal depresses but harder than I would expect without vacumn to booster. About the same pedal as a diesel pickup engine not running. I did bench bleed the master on the car, never got a good stream from the tubes into the master.

If you didn't get a good stream then the master is not properly bled.  You can do this with the master on the car so try again.
Extraordinary claims require extraordinary evidence.

I have a kit from Pirate Jack. it was pretty straight forward.

Hard pedal? are you getting vacuum to the booster?

fizz

don't have engine in yet so trying without vacumn

Hard Charger

when I installed the kit before I started the engine (for vacuum) the pedal was rock hard, barely moved.

sounds like that is your problem.

I bought the Bendix style booster right when it hit the market 2 years ago.
