To keep a long story short, I'm bleeding my brakes, having no problem
with 3 of the four wheels.  On one of the front calipers, I can get the
BOTTOM bleeder to bleed clear brake fluid with no problem, but the TOP
bleeder gives me nothing.

I pulled both bleeder valves off, removed the incoming line from the
brake hose and pushed compressed air through the bottom bleeder, but
nothing will go through the top one.  I take it that the incoming line
feeds both through internal channels and that one is probably the left
pad and the other for the right pad.

Anyone have a diagram of internal fluid distribution? Is there any other
choice but to pull the caliper and rebuild it (or buy a new one)?
