@middlecalf maybe has more on the specific year. Small brain thinking here, drum shoes are more snug therefore pushing more air pressure to bleed? Just my .o2
Edit.Brake line questionable to not hold pressure? Cracked etc.
Disc brake bleeder screw for top. Drums get the middle/bottom.
Take a step back for a minute and go back.
Only for a 1979 40, my info.
I always remind myself, these are stupid awesome vehicles.....ain't that hard...don't overthink.
Rear bleeder on a 79 fj40.
I bled the hell out of mine to be honest, helps to have another person. "Down ok hold" for the other person.
Bleed more than you would think to.
Or a one man bleeder kit.
Excellent advice I went though what you are describing. And the parts replaced. Bled brakes over and over.
My solution was to do as described, but I adjusted the pads with more "drag" than I thought needed.
This seemed to firm up the brake pedal, and the pads "seated in".
Have also had new...
