    Need some help. I just bought a 97 gtp. The previous owner replaced the m/c a few months before I bought it. He advised me that the brakes were soft and it needed to be bled. No problem. I bled the ABS modulator valve then went to the rear brakes. I have no pressure in the rear right caliper and the left had a frozen bleeder valve. Its old so I said to hell with it and bought new calipers for the rear. The left bled fine...the right still has no pressure. I checked the front, they have pressure. I pushed fluid through the caliper with the line disconnected, all good. Pushed fluids through the caliper with the line conneceted...no go. Dissconneced the line @ the modulator valve and pushed fluid through..no problem. The issue seemed to be the modulator valve but I was under the impression. That the rear lines were run off a single valve unlike the front. Is this wrong. Is it possible something I missed. Can the modulator valve be rebuilt? What are my options. A new modulator valve is $5000...I rather not spend that if I don't have to. Any help would be great

    Did you try starting the car and bleeding them? Maybe there is a little blockage and the extra pressure will help you bleed them.

    Dropped it off to my mechanic for an alignment today. He's gonna take a look @ it for a second oppinion. Hopefully I've been over thinking it and its something simple and cheap
