Help me bleed my brakes

Maybe its a bit extra fluid, but then I don't have to worry that any old fluid is left. an old BMWCCA trick (well, thats where I learned it) is to switch back and forth between ATE 200 yellow and ATE super blue (same fluid, different colors). Then it is clearly visible when you can expunged all the old fluid. Plus, in my experience, VERY little fluid is sucked back up, most of my master cylinders have done a great job of sucking new fluid from the resivoir (clutches are a different story, because the spring pressure pushes everything back up to the master).

I don't think you can get Super Blue any more. Something about the DOT requires all brake fluid to be yellow/clear in color and it took them 20+ years to notice or give a E36 M3 about Super Blue being, in fact, blue. Whodathunkit???

you can ... it's just hard to find .. and it's marked "for off road use only"

I have 2 cases

Thanks all, I'm going to gravity bleed and see if I can get the line full first. I'll try with key on as well for the ABS. I'll let you know what happens.

Here's a free setup that does exactly that.

How would this keep the same fluid(or potentially air) that came out of the caliper from getting drawn back in when you release the brake pedal?

Friction. No loops or upturns are necessary.

Key on won't necessarily help with the ABS. You have to cycle the pump by either triggering the ABS or (on some cars) doing it via various electrical tricks.
