no brake fluid coming out of calipers on dads 4runner after new MC

[blondejoncherokee]

trying to help my pops out on his
2000 4runner
ABS
brake pedal would drop to the floor at red lights slowly after being stopped a while.

so we replace the booster/MC
bled the rears
went fine.

bled the fronts,
fluid came out, then nothing. pumped and pumped. nothing
tghe chiltons says "bleed the brakes"

i was wondering if there is any specific way to bleed an ABS system?

as i see it there are a few possibilities:

1. we did not get all of the air out of the MC while bench bleeding
2.the new reman. MC is bad/crappy
3. there is somethign up with the ABS system, somethign isnt opening??
4.something else?


does anyone know what might possibly be wrong?
i dont live close otherwise id be out there rebleeding the master and checking to make sure we get fluid from all the lines to anf from the ABS.

we think the push rod on the booster is too far inward
therefore the braking starts at the end or after the fronts are even used, therefore no fluid going to the front if it starts past them.
a toyota tech told us this
ill try it out tonight

Being a Toyota tech, I've not bled a Toyota ABS system yet, but I've heard it's no fun and very irritating.

are there bleeders on the ABS module?
