So my 1983 60 did not run for about 8 years and finally got it going and enjoying it again... brakes were terrible at first start, changed bad rear wheel cylinders, adjusted rear brakes and bled the fluid several times because pedal would go all the way to the floor. I finally got the air bubbles out (I think) and brake pedal feels a lot better but still spongy, pulls right and wobbles like crazy when braking at high speeds. I had done the 4 runner caliper/mc upgrade about 10 years ago... I have been reading that 4 runner upgrade does not improve anything and I don’t want to spend the $$ for the tundra upgrade since I would bigger than 15” wheels, more $$. I am thinking of going back to the FJ60 calipers and master cylinder unless there’s a better option that does not involve changing wheels?? Any suggestions? I occasionally might pull an off road trailer or my fishing boat
