I've done the buddy system and the coke bottle thing (both at the
same time actually, just to be 100% sure no air would be introduced at
the bleeder) except that my "buddy" is a ratcheting bar clamp wedged
between the pedal and the front of the seat. Its "bled" in that I'm
getting clean fluid without bubbles, but there is obviously air left
in the system somewhere. Should I just keep pushing fluid through it
and hope the air comes out eventually, or switch to plan B (whatever
that might be?) :-)
I suppose I could try vacuum bleeding; if there is some air
trapped somewhere, maybe its moving down when the pedal is pressed
but moves back up by the time the pedal is pumped again; the constant
suction of a vacuum bleed might be enough to convince it to move
through the system. I've never had great luck with vacuum bleeding
just because its hard to tell wether you are actually bleeding air
from the system or if the bubbles are from the outside, sneaking
past the bleeder threads. Thread sealant helps, but I've never
been able to completely eliminate air from getting past the threads.
I might just put a vaccum on each bleeder for a fairly decent amount
of time and then bleed the system normally.
As far as pressure bleeding goes, I don't have the equipment
to do that (nor do I have the special tool to hold the proportioning
valve open which would be required to pressure bleed this vehicle).
