Help brake bleeding - 93 3.2 m104

[redkx]

I am stuck on bleeding my brakes using the 'family method'..my son presss the pedal...I started from my passanger rear and did not progress any further.
At first, the dirty greenish color fluid came out pretty good.
I got about half a cup.
Then I notice something is very wrong.
The fluid is dripping slower and slower with each pedal depression.
The brake reservoir level remained unchanged!?
I started the engine a few time hoping it will change something...nothing.
I think I am draining the fluid from the ABS unit.

I got no brakes...sponge pedal.

Is there a proper method to breed the brake system?
How am I going to correct this situation.

Your input will be greatly appreciated.
Thanks
Earl
