I’d get a motive power bleeder or watch a video on bench bleeding. I’ve
heard old timers say they’ve never done anything but gravity bleed but I’m
not sure I have the patience. After I drained all my brake fluid replacing
my rear rubber brake hoses because the nut was stuck. I power bled my
system and the brakes were still a bit spongy, waited 24hrs for the brake
fluid to calm down and power bled some more and they were still a bit
spongy, it took a little time but they firmed up. I also upgraded the
booster so the pedal feel is totally different now. You may as well upgrade
to the metal brake hoses since you have to drain the fluid anyway. Not sure
if you can wait on parts, I always end up just over hauling everything in
the system once I open Pandora’s box.
