bleeding brakes
 
So I'm having issue with bleeding the brakes, not to sure what's going on.. Ive removed the abs and put in new brake lines for the front and part line for the rear.. I pump the brakes and air is releasing through the vaccum line that goes to the engine.. Then I reattach it to the engine and same thing .. The fluid is moving around in the container but not going through the lines

The vacuum hose from the booster won't affect the bleeding process. When you say container, do you mean the master cylinder reservoir? If so then it sounds like you've routed fluid back to it somehow when you replaced the abs.

yea sorry, master cylinder reservoir, I couldn't think of the word aha.

From the master cylinder I have:
Port 1 ( on the side) splits off to front brakes - banjo fitting to SS Flex brake line
Port 2 (front) goes to a ssbc valve then to rear brakes- banjo fitting to SS Flex brake line

no fluid gets pushed to the brake lines it seems like

Thanks for the response

Maybe try bench bleeding the master cylinder?

At nearly 30 years old the proportioning valves can get clogged up. Disconnect the lines that exit the prop valve out to the brakes. Pump the pedal and see if brake fluid starts spewing out both front and rear ports. If not I would remove it and clean it thoroughly.

just loosened up the banjo bolts, let some fluid squirt out and it was fine after, makes no sense but whatever

It does make sense, you bleed the master cyl. Now that its bleed you can get enough pressure to push the air out of the system

+1, my master was dry after I did an ABS delete and it wouldn't let any fluid through without bleeding the master first
