... It is never a good idea to use a pump to get rid of air,
.... A vacuum brake bleeder removes air, all air, something near impossible to do using ordinary bleed screws.
Here is one of those threads about vacuum bleeder
I used a syringe with a long clear hose to see through and ensure any bubbles (and there were none) do not reach the nipple while pushing fluid in in 1 single stroke over a few minute (blocking the piston, btw!) until the fluid shows up in the top reservoir.
Vacuum bleeding means the only exit is down, fighting air bubbles that want to go up.
Not to mention how off-throwing it is to see endless bubbles coming from the bleeder valve simply not being air tight.
That's the whole advantage of pressuring fluid from below and upward. If the bleeder valve isn't sealed, sure it may leak fluid under pressure but no air gets in.
I cannot conceive of the physics it would take to claim vacuum is better unless one could vacuum from the top reservoir, and even them air would sneak in from the bleeder. There is a reason the manual wants you to pressure the pedal to exit the fluid.
I'd rather say vacuum is never a good idea...
But that is beside my question.
I only want to know if there are special moves to make in relation to ABS
, like run it, get it to activate, tilt it, or anything suspiciously missing from manual that long bearded mechanics know about...
