BAD brakes

I have a 95 lumina with just over 100K on it. As you all know that own these cars the brakes were never the best but about 2 months ago I had a lower ball joint and CV axle go out while driving it and the left front ( drivers ) side wheel turned 90 degrees and the car also dropped. The shop that did the repairs did not mention the fact that after doing the repairs that it had NO brakes! ( only that the rotors were rusty ) Before these parts went out I could at least stop, now it seems like there is no fluid in it. I have refilled the resevoir 2-3 times but can not see where any brake fluid is going.
I just looked on the invoice of the repair job and they added brake fluid also, wouldn't that give them some clue that there was something else wrong?
Any ideas or sugestions?

Someone has to get it up in the air and look ,what other way is there to approach this?

It may have pulled hard enough on the brake hose to break the support where it joins the hard line...the line may be leaking now if it was rusty and got flexed...

They should have replaced that brake hose and inspected the lines....that hose had to have gotten yanked hard...

I have had the car jacked up and had another person apply the brakes while I was under the car and could not see where any fluid was leaking. The connection where the brake line coneccts to the hose did not leak ( visably anyway ) . Still stumped.

Take it back to the shop and tell them that you have no breaks. They should have fixed that problem the first time or at least let you know that there was a problem.

I would have taken it back to the shop ( gas station ) where the repairs were first done but it is about 15-20 miles away and with out any brakes it makes it a bad trip to take. With what happened to it you would think that anything that MAY be wrong with it is on the same side but I have not beeen able to locate any brake fluid leak but it IS going somewhere. I have looked at the lines while the pedal is being depressed and see no visable fluid.

The fluid could be getting sucked into the booster through the back seal of the MC. When this happens you lose fluid but you'll never see the leak.

Please note the date on any thread before replying, this is way too old, thanks.
