Multiple problems with bleeding brakes

Does anything in California work right?
I don't know anything about crush-washers on Mopar brakes, but if they ain't made of copper, then throw them away and get coppers. Coppers are reddish in color, not chrome and shiny. Aluminum will work in a pinch, certainly better than chrome-plated.

As for the vacuum bleeders, bubbling after the bleeder is tight, is sorta normal. Like said; the hose is just not tight enough on the bleeder, or it's pulling air from down the threads; I anti-seize the bleeder threads, and got used to seeing some of them.

As for brake lines; I learned to double-flare them and make my own. So if one leaks, I know who to blame,lol; Yeah not every flare is perfect........but mostly they are.
