bleeding Duo Discus brakes

Good luck . . .

And if it is Dot fluid, be really careful about clean up, given some
time this stuff is as good a paint remover as anything else. Once upon
a long time ago, I thought I was being fastidious cleaning up and used
compressed air to blow out one of the tubes I'd used for bleeding. The
little bits of brake fluid spray settled unnoticed on my car hood and
fender some 25 feet away. Next morning that car had a serious case of
the measels.
