<DIV><FONT size=2>I can't see that it does as by the time you get to the pistons
they are completely separate circuits, however perhaps one should still
bleed the longest front circuit first (the difference between the rears is
probably only a few inches in several feet). I can't really see why
it has to be done anyway. Some places talk about air bubbles passing the
shortest circuit when bleeding the longest, so if the shortest has already been
done it could leave bubbles in there. But that can happen regardless of
which you are doing, and once you have bled the first circuit (longest or
shortest) there shouldn't be any bubbles in that circuit. It's perhaps
more relevant to stop-start bleeding with the pedal where fluid and hence
bubbles could be moving back and fore, less so with continuous pressure such as
EeziBleed. </FONT></DIV>

<DIV><FONT size=2>I've never done it, but I'd imagine pedal bleeding is a bit of
a pain on a dual circuit as a 'good' circuit i.e. no air should
be limiting how far the pedal can move when bleeding the one with air
in.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>There is also the question of the balance switch. I understand
that on the earlier unboosted system the switch will always be tripped, and
careful re-bleeding of first one circuit then another may be needed to
centralise it again. With the boosted system the switch can be partially
unscrewed to stop it latching. But then again will low-pressure bleeding
such as with an EeziBleed on just a few psi be enough to cause the shuttle to
move anyway?</FONT></DIV>

<DIV dir=auto> On vehicles with independent front and rear brake
hydraulic circuits, is it still advisable to bleed the longest pipe run first?
That is, does it matter if one bleeds the front brakes
first?</DIV></BLOCKQUOTE></BODY></HTML>
