I'm rebuilding the ATE calipers on my 1985. I've never understood why there
are two bleeders. It makes sense to bleed from the top of the caliper, but
why is there a bleeder at the bottom? Is there something I need to do now
that I've drained the fluid out of the caliper? I'm reluctant to do
anything with it since it's never been opened. If it snaps off . . . .
