Lol, i know. What is the remedy or options to get it to work? I do have fluid back here but when i pump the brakes and try and bleed the system no pressure back here. Fronts pumped perfect with the hose and bottle setup. Cleared out the old fluid and the fronts pumped through new clear fluid. Come on rear brakes BLEED!!!!!!

Sounds like your compensator is clogged. Or the junction near it is.

Better off buying a new rear brake compensator valve. You can get a new one for about $30, make sure to disconnect the linkage from the differential first, then carefully loosen the two 10mm brake fittings. Use PB blaster, wire brush the threads. Once the fittings are out remove the three 13mm nuts inside the rear panhard bracket to remove the whole brake compensator assembly. Also, before throwing out old compensator, be sure to remove the cylindrical locating pin (where the linkage rod meets the push rod) without destroying it. You will also want to buy new small clear bushings (x4) that go between the linkage arm and the diff.

Be sure to replace the flex brake lines as well including the one to the compensator. They can delaminate inside and create a one-way valve issue that doesn't allow free flow of brake fluid.

It's an easy fix once you get everything apart.

I suggest jacking the car up and soaking everything you might need to loosen with PB Blaster, multiple times, then letting it sit overnight.

Sometimes it takes a couple soakings to loosen a stuck nut, but eventually they do break free.

Thanks Joe, thats the part that makes me nervous. Hopefully they loosen up after a good soaking. Also, i have never changed one so this will be a nice lesson for me. I appreciate all the info so much from everyone, it is really helping me along. Thank you everyone!!!!!

I have had success using a pair of locking pliers to remove stubborn brake fittings. Remove the rear passenger wheel and loosen the fittings before trying to remove any bolts on the linkage.

+1 on that. Soak with PB and tap lightly with a small hammer to help the PB penetrate into the threads and they will usually come loose.
