ABS isn't my friend
i am having some problems with my abs in my 93se.
Sometimes my abs light will come on 20 seconds after I start driving, sometimes 20 minutes, sometimes when I hit a bump, sometimes never. But the main thing that scares me is, I start up my car, immediately start driving, and the first time that I go to hit the brakes, it feels like the brake pedal comes up really high for a second, then i will lose almost all brake pressure for another 2 seconds, then brakes will be back to normal and the ABS light will now come on. This usually only happens when I am in a rush (delivering pizzas) and I don't wait at all to start the car with the key in the ON position. Could this be my prob? do i just need to wait for a few seconds in the on position, or do i have some abs problem. could it be a relay or a sensor?? please help it will be appreciated.

Well I dont know if this is the exact thing that happend to me or what but... Before I changed my master cylinder .. the piston inside it would seeze and my brakes would stay fully applied until I let go of the pedal. And my ABS light would come on. Maybe your MC is leaking or it is dirty... I would suggest you look for leaks and if you dont find any I would flush my brakes , bleed etc.
Good Luck.

humm.. if it'* intermittant.. it maybe a speed/wheel sensor within the hub. Could be wrong though ( which I have been before.. but I think if it'* a mechanical thing.. it usually works.. or it doesn't unless it'* something electronic ( which leads to the speed sensor ) or loose wiring )
Do check the brake fluid and see what color it is and try wat Russian polar says ( cheaper then wheel sensor which means you'll have to replace the the whole unit cause it doesn't separete from the bearing )
