Spongy pedal after axle swap

[Stuka]

Ha! Hey the brakes work and i can lock them up no problem, it just takes full pedal travel to get there. Im pretty sure a larger master will solve the issue. I locked up the 42's while being pulled by my wife in my other truck. So i wont run over you...more than once anyways

If you have a ford 60 with the dual piston calipers, they do require more fluid to work. So a larger master would make sense, provided the plunger pushes more fluid.

NO doubt & it will wreak havoc with a disk drum PPV.

Does anyone have a cross reference for a master cylinder with a larger bore that will bolt up to a mid 80's booster? I have a 1 5/16" master but its going to take some work to make it work.

Well, after a bit of searching a finding a cardone master cylinder guide, i think i have found the part i need. Its 13-2739 if anyone ever needs it. 1 1/4" bore, 1/2" primary and 9/16" secondary prots (same as all FSJ's) and $49 from rockauto. Link to master cylinder list below. I should know in a week or so if it bolts up properly.
