Thanks to everyone for the rapid responses. Lots to consider. The brakes are
not currently binding. The original problem was a too long pushrod in an
upgraded master. That's corrected and there is ample fee movement. Now I
can't get a good pedal after bleeding. I'll make another thorough look at
everything including the master ( not assuming that it was overhauled
correctly).
I'll report back.
