ABS Bleed Necessary?
Hi everyone:
I know the answer to this is most definitely already posted somewhere, but I've looked and can't find just a straight-forward answer, and I'm going cross-eyed haha
I need to replace my Brake Master Cylinder, but like an idiot, I waited too long and got lazy, letting the fluid leak out of the seals/grommets. So here lies the issue, as I do not have a fancy Hawkeye scanner, etc... How do I get the air out of the ABS module? I assume since I pressed the brakes after letting the reservoir empty, that I can't just bleed the system at the BMC lines as I've read in a couple places, right? So, how do I get the air out of the ABS, and do I do that before or after I bleed at the wheels?
Thanks!

There are instructions to make a switch you can us at the ABS relay to operate the pump. You’ll also need to bench bleed the master cylinder.You could always go get an obdII tool that bleeds brakes as well. There are a few now.

I thought a bench bleed wasn't recommended with our BMC's because of the rear brake reservoir being a potential failure point, no? Most things I've read recommend bleeding the cylinder by backing off the lines going into the res. with pedal pumping. What are your thoughts?

You could be right, but that is news to me. I did the bench bleed to mine, and not sure how it would be different from any other BMC.
