Try this method.
At this point you have nothing to loose.
Worked for me a time or two, when i was professionally wrenching for a living, when i had a problem child in the brake system.

I call this method "reverse bleeding."

Let me explain what to do.

Get yourself one of these little "squirt cans" and put a length of rubber hose on the end of it.
Fill it up with brake fluid.
Take out some brake fluid from the reservoirs in the master cylinder.
Hook up the hose to the bleeder screw rt rear. lt rear, rt front, lt front, and squirt fluid into the system, back up into the master cylinder.
You are essentially forcing fluid and any air, back up into the highest point of the brake system, which now is the master cylinder, in the engine compartment.
Keep removing fluid out of the master cylinder, if you don't mind it overflowing all over the place.
Might just work for you, who knows, give it a try.

You appear to be right up the street from me in CH, as I'm on the Sunrise Blvd, side of Rancho.
Good luck.

Oh, one other thing to mention after i got done writing all of the above.
How are your rubber flex hoses on the rt, and lt, front, and the at the rear over the axle?


****Rears still drum? Are they adjusted up?****

As others have already stated, this is also very important.
