Thank you for all the tips and suggestions. Unfortunate I got sick right after this happened and I have not been able to give the truck my full attention. I was able to spend a few hours bleeding the brakes with the bleeder I posted the link to. I saw all the old fluid come out, followed by a ton of air, then new fluid, with still some air bubbles. I was not able to put the time in to get all the air out before I got sick. I am leaving for vacation tomorrow (luckily in my wife's truck) so my truck is being dropped off at my mechanic so he can bleed the brakes and ABS controller while I am gone. Thanks again for the tips!
