2001 Sonoma Brakes
 

The MC most likely went empty due to a blown line. I replaced the line and can not build pressure. I have clean fluid at all four corners when vacuum bleeding. I bench bled the MC and still cant get any pressure at the pedal. Any help would be appreciated. I'm suspecting ABS module has air, but I don't know how to bleed that, and im pulling fluid through it to get it out the bleeders. Stuck

I'm a newbie with these trucks and anything this new. But I think you are correct that it's the ABS module hanging you up. I ran into the same problem bleeding my son's '08 Toyota Xrunner. But I don't remember how we worked that out. Hopefully someone will have your answer

google will tell you that you need a tech ii or equivlent to cycle the abs module to bleed the brakes. There is really no other way to do it. Been this way for nearly 30 or so years now.
