[Mgs] Brake frustrations

[Paul Hunt]

How are you bleeding?  With a split system I think you have to use a
continuous pressure method like the EeziBleed, as back pressure from the front
circuit should be limiting movement of the pedal which affects pedal bleeding
of the rears, and vice-versa.  Because of the limited pedal movement you can't
get much pressure in the circuit you are trying to bleed, and as it is full of
air that is taking 99% of the pressure meaning there is very little pressure
left to force fluid through the (probably) empty system which means it will
take a long time.

But the whole point with a split system is that if the pedal really *is* going
all the way to the floor, then you have a problem with *both* circuits.  If
that was an exaggeration in frustration and the pedal *isn't* going to the
floor and *is* developing satisfactory pressure to the fronts as you state
elsewhere, but can't get any fluid out of the rear bleeders, then you need to
hook up an EeziBleed while you slacken (and retighten!) various pipe
connections throughout the rear circuit to see if and where you have a
blockage.  Even with an EeziBleed pressure isn't that high and it can take
several minutes to get fluid though the system.  If you don't want to get an
EeziBleed but have a helper then tell them to hold the brake pedal down hard
rather than pumping.
