1993 Buick Skylark.  3.3L w/3spd. automatic, 115,000 miles.  

This car is immaculate.  About a week ago, the brakes lost **almost** all prssure.  I was able to stop the car, however there is no pedal, and flooring it makes it creep to a stop.  

I went out to the driveway the next day, and found a puddle under the left rear wheel. *GREAT*.  Jacked up, removed wheel, located a ruptured steel line just after the rubber one (Between the rubber, and the wheel cylinder).  Went to National Auto, purchased an 18" piece of steel line, and a giant-economy size bottle of ABS-approved DOT-3 brake fluid.  I went home, replaced the line, and filled the resivoir.  Called my girlfriend out and went throught the drill of bleeding the brakes.  

Here comes the puzzling part.

I have no E Brake warning light or ABS light on, and I only get strong fluid pressure from the left front wheel when bleeding, and no change in pedal. The rest of the wheels just trickle fluid, and it has no real pressure behind it.

I discovered two bleeders on the ABS unit itself, I treated them both the same way as the wheels.  Pump the pedal, open one, got good pressure from the one directly facing the front of the car.  The other bleeder, facing the right-side headlight diagonally, barely trickles, and has very minimal air pressure, when the pedal is pumped.

I am having difficulty being convinced that the steel line, and the ABS unit both went bad at the same time.

Can someone help me???  

Tough to say. I think I would try bleeding all the brakes again. either you have air in the system yet or there is some type of dirt and debri in there somewere. You may mind that the ABS unit itself is bad.  

bleed the master cylinder first then the wheels
