Listers,
Something I ran across recently that I would like to share.
When bleeding using the pedal bleeding method (as opposed to the vacuum
pump method) limit the travel of the brake pedal. If you allow the piston
in a used master cylinder to travel beyond the area of normal travel, the
layer of gunk on the cylinder wall can tear up the cups, causing failure of
the master shortly after. Put a block or blocks under the brake pedal to
hold it about as far off the floor as it is when the brake is applied. If
you happen to be replacing or rebuilding the master at the same time, so
that you know the bore is clean all the way down, this caveat does not
apply.
