RE: Disc brakes.

[William Cole <wedge64@xxxxxxxxxxx>]

Thanks Dan,
I did get the rebuilt calipers for a 73-76 A body car. Just don't know
the piston diameter of the MC. And I'm sure I have the bleeder on the
top. I did bleed them the way you described. I've bleed brakes many many
times in my life. I may try a different MC before I go and buy a whole
new disc system.
