    Bleeding the anti-lock brake system is really not much different than a standard braking system although we should still use caution. You're going to want to make sure that the key is off and it's probably a good idea to remove the ABS relay as well as the fuse.

    The easiest way to bleed the ABS unit is with a Tech2. I'm not sure if there are other ways to do it, I've never needed to bother because I have the proper tooling to do it the way GM specifies it should be done. ABS bleeding should be done first, as it pushes air from the BPMV into the steel lines, then conventional bleeding after that.
