'91 se turbo

Rear brake was dragging so much that it began to smoke on both rear sides.

Facts:

Installed new master

Bled brakes, noticing that rear brakes have minimal flow, not enough to fill the hose completely.

Installed new caliper on pass rear (did not solve)

My next thought was that both rear rubber brake lines had collasped and fluid was not being allowed to return forward and was only going in the direction of the caliper thus causing the brake to burn up...

Changed rear dr. brake hose, could not get pass side off so it stays for the moment.

What I have noticed before and after changing brake hose is that flow of brake fluid while bleeding has been minimal and not strong despite the new master; condition was occuring before new master which is initially why I replaced the master b/c the flow was so weak and minimal while bleeding.

After installing the new hose on the dr. side I began to bleed the system I got some flow but not enough to solidly fill the hose and lower the level in the brake resovoir...I am at a loss now we have a new master, a new caliper and a new brake line.

Any help appreciated.
