Alright, i was changing the diff fluids the other day and noticed that it was finally time to do a brake rebuild, go figure. So i got the 40 up on jack stands in the rear right now, first i started with emptying the old fluid and replacing it with new. I am having trouble deciding if i should change the brake lines, if they aren't leaking, do they need to be replaced??? They are definatly original from 1979. The rear cylinder have supposably been replaced, so i tryed to remove the drums, how do i do this, do i unbolt the 8 bolts then knock it off? I'm having some trouble bleeding as well, i had no problem bleading the clutch. Now that there is air in the rear brakes, do i need to also bleed the front?? Do i bleed each side of the rear separatly or what?
