Is there some trick to bleeding the RWABS I'm missing here? Didn't see a thing about it in the Haynes, but that's usually useless. This is after a COMPLETE brake overhaul + rear disc swap, only things not replaced are the hardlines (& ABS stuff, that bunch of valves below the MC), those I flushed out with brake cleaner & compressed air, so the system was completely dry at one point. Got the fronts bled with no problem but I'm getting NOTHING at the rear. Tried gravity bleed, mityvac, even my pressure bleeder does nothing. Tried cycling the key on & off. I do have the brake light on on the dash. Is there a valve I'm missing somewhere that needs bleeding? It feels like there may be a couple of bleeder ports on that valve block below the MC, but the rubber caps don't come off easily so I don't want to force em.
Can someone help me out here quick? I'm soooo close to finally having this fiasco done, I want to get on to chasing leaks already!
