72 Duster Resurrection
Ok, so I have the front rotor and calipers back on and have greased all my suspension.
Almost ready to drive, I just need help with one final thing:
I cannot get the rear drum brakes bled for the life of me.
After I installed everything, I bled the master cylinder, then started from the farthest wheel cylinder to the closest and bled using a helper, then the hose in bottle method.
When someone holds the pedal down and I crack the bleeders on the front disk calipers, I get clean air free fluid to come out.
But I can not get any fluid to be delivered to the back drums.
The brakes are still very spongy and will work only if you pump them. And only then on the front. Rear drums do nothing because they are getting no fluid.
My entire brake system is new. I even shot compressed air down the new hard line going to the rear while both rear drum bleeders were open and I got air to blast out the bleeders. So there's no blockage (again, all lines and cylinders are brand new).
I suspect my distribution block/ proportioning valve is faulty.
I bought one of these brand new from Inline for this:
This is the correct part for my 72 all drum car to 74 front disk conversion, right?
I detached the line going from this block to the rear of the car and had someone press the brakes and got a weak trickle out that port.....
Any thoughts? This is the only thing stopping the car from driving now.
