    I just changed rear end in my 53. Now I can't get the rear brakes to bleed. There is fluid to the tee
    the lines to the brake cylinders are clear. I'm at wits end I haven't had such a problem in the past. It has drums all the way around. Any ideas?

    Not sure what could be happening...
    do you have a dual reservoir master cylinder?
    Maybe its not pumping from one reservoir?

    Yes it has a dual reservoir.

    By chance did the rear MC reservoir go dry during the rear end swap? If so, a master cylinder bench bleed may be in order.

    Just get some speed bleeders from Summit. $9 a piece. Problem solved.

    Is it a possibility that the MC went bad? If its an old master and you pushed the pedal past its normal travel, you could of dragged the O rings through some rust causing an internal leak. :Do No:

    Good call; that's happened to me more than once or twice.

    I guess that is possible Jason, but the system was installed new about 4 years ago and I'm in a very dry climate. I ran a line
    from the tee to a can with brake fluid with the end of the line submerged in the fluid. I could raise the level of the fluid by pumping the brakes. I don't know if this means anything or not.

    Thanks for the replies I have the problem solved. A little miscommunication. I thought the guy who set up the rear end for me rebuilt the wheel cylinders. I was wrong and they were a mess. I'm glad they didn't bleed out. I had a couple I had rebuilt a while back. Problem solved.

    I'm not sure of the thread size maybe someone else will chime in. I know they cover a lot of years with one size.
