Brakes don't behave ANY differently than before.
I got a NEW OEM AISIN master cylinder from Burt this afternoon, bench bled it, installed it, bled the brakes, and gave it a try.
Pedal travels fairly far on the first pump (6-8 inches), and stops the truck pretty fast when moving. Second pump travels less, harder to stop the truck (feels more like braking with the engine off), third travels less etc.
(basically it is pumping up)
Engine idle gets jumpy and idles down slightly when pumping the brakes at idle just sitting in place. Pedal swooshes somewhat like before.
We think there's still a little air in the lines, but not much because the pedal isn't squishy, once it gets hard it's hard.
1) Does it sound like the booster I yanked off of the FJ60 is also a bad one?
2) If the booster is bad, is there still a danger (as I guess there was before) of running 5 and 6 cylinders lean and burning stuff?
3) Cany somebody or everybody with an FJ40/55 describe what their brakes do? Or confirm if they observe the same behavior from their brakes?
4) Did I miss something in the bleeding procedure?
5) I had to cut the rod on the new booster, does it sound like I may be having a conflict with that?
6) Any other ideas? Wheel cylinders seem to be fine, no leakage or anything...
