As old as the car is, it's probably not worth spending a lot of money fixing the abs. To fix it as original, you would take the car to the GM dealer to repair it. If it was my car I would check the brake lines for leaks, bypass the abs unit,bleed the wheel cylinders and see how the brakes work. If you have low brake pressure, you might then have to replace the master cylinder, then bleed all the wheel cylinders.

is there any brake fluid leaking or on the wheels?

Check to see if the brake line that goes to the rear brakes can be disconnected up in the engine compartment, and have an assistant push on the brake pedal, to see if brake fluid is flowing. If you can't get fluid from the master cylinder, it might be a bad master cylinder.

Yeah either the master cylinder or faulty lines ...

Simas i forgot to mention the brake pedal is locked in the down position which means brake pressure is low the front brakes barely have enough to try and stop

See if you can get a rebuilt master cylinder, you might try advance auto parts on line. they usually have a discount and you can still pick up the part at the advance store.

try hitting the brake pedal with your foot as if you were using it to stop and it might come up..... and btw you need to change the master cylinder and your golden
