My brake master was leaking out the back so I replaced it... No big deal pull out the new master, clamp in vice, fill with fluid, allow to bleed thru, grab screw driver and work the plunger a little getting more air(while holding fingers over the brake line ports to keep air from sucking back). Install on truck and bleed the lines at master, then bleed all 4 wheels to ensure all air is removed. Well thats not working today. Brakes are spongy and I can pump them up to get somewhat of a pedal. Anyone know of any issues or tricks with these 91 F350's 4x4's??? I know there is a rear antilock actuator up almost under the master on the frame rail... I have bleed it there also and no air comes out.
