ok ive been round and round with this .first take off the proportioning valve thts the thing in the right rear on the frame rail that t's all the brake lines i cleaned it with brake cleaner then blew it out with air line .then diconnect the brake lines at the master cylinder and all calipers and rear cylinders blow air threw them this get all residue out of lines .connect all lines up open all bleeder valves add fluid when fluid is flowing fully from front tighten them, then rear aftre it may tke a while then do the regular bleed ruteen with pumping the brake starting with (this is important ) lr then rr then rf then lf then the ppvalve . good luck

 

make sure your shoes are adjusted correctly. if its too far out the MC doesnt displace enough volume to push the shoes out enough.
