95 Lumina APV ABS Master cyl replacement?

[ohiobenz]

i'm working on a friends APV. It all started because the front subframe broke in 2 pieces. That all ruined the drivers side driveshaft, ripped the motor mounts apart etc.

As he babies driving this thing till i can find a used subframe (rare item to find without being rotted for some reason) his brakes go out. Intersting enough he was trying not to use the brakes because it twisted his whole frame...

It appears the rear seal in the master cyl blew - there was fluid all over the booster and the firewall area.

I picked up a subframe etc and a rebuilt master cyl - now some Q's....

how do i separate the MC from the ABS pump?
what do i have to do to bleed the system?
since the fluid is/was all gone - is there anything special that has to be done to the ABS unit?
is there anything i can't do with basic tools etc?

TAI!!

Found that not all the fluid was gone - only front reservoir was empty.
Had to remove motor pack to gain access to the banjo bolts that connect the MC to the ABS pump.

When removing the motor pack, all 3 motors were still under tension. The 3 (pump?) gears all rotated some when separated from the motor drive gear.

How do I reset the motor/pump gear after/during re-assembly?
How do I bench bleed the MC before re-installing it??

thanks
