[Healeys] 100-6 BN4 brake bleeding - follow up

[Simon Lachlan]

Note:-
An interpretation of the paragraph, below, might imply that one tightens the
bleeder just as the pedal's downward stroke is ending. Not after it's
finished. That way no air can come in against the outward flow of fluid.
Works for me.

re: "... tighten the bleeder screw at the end of each downward stoke of the
pedal and allow the pedal to return fully before re-opening it ..."

That's how I was taught to do it.  Also, don't open the bleeder until
there's pressure on the pedal (the other half of the equation).

Since I usually don't have help, I made my own pressure bleeder by affixing
a Shrader valve to a reservoir cap.  About 10psi on the valve seems about
right; since there's always pressure on the system I think you're less
inclined to draw in any air.
