The patient - 74 Plymouth Duster, Factory 318 car with power disc/drum brakes. I bought the car disassembled but the brake system was together and intact so I don't know if it ever worked 100% when the car was taken off the road for restoration.
The problem - No fluid getting to the back brakes.
I attempted to bleed them and no fluid getting back there. The fronts bled fine. I tried to remove the hard line out of the distribution block to the back brakes and see what I had there. It would not come out so I soaked it in penetrant. My impatience led me to pull the plug out of the bottom of the distribution block. The plug, the spring seat and the spring came out in my hand along with some but not lots of fluid and some but not lots of black specs of crap. The spring seemed to be under a quite a bit of pressure when I removed the plug but all went back together fine. When I pulled the plug a second time, the spring pressure was not there. The spring sat up in position and wasn't forced out by spring pressure.
Did I screw up my distribution block, prop valve, brake trouble switch?
Is it possible my fluid blockage is in the distribution block or is it more likely to be in the lines to the back?
My FSM is at home so a picture of the inner workings of the distribution block would be great if someone had one.
Any ideas to ponder or experience with a similar issue would be great.
