I have a 94 and I been losing brake fluid when the ASR, ABS lights come on every 4 months approx. I see no leaks in the master cylinder and no leaks under the pedal. Can anyone point me to the possible problem?

Check where the MC bolts to the booster, use your hand to feel around the bottom of the MC and check for fluid on your hand. Pull each wheel and check the calipers and lines for fluid seepage (dampness). If you have access to a lift it will make it easier. Lastly the ABS modulator/pump is located in the storage compartment behind the drivers seat--check the fittings and brake lines there also.

This covers it pretty much.

Also look at the return line from the side of the master reservoir down to the ABS pump.

Any sign of dampness I would follow up on.

Hopefully you're not filling up the ABS pump compartment with fluid.

I will check those areas when I get a hold of my friends lift. I had the rotors replaced a year ago. Do you think it has something to do with that?

I just fill the brake reservoir but never checked the ABS pump.

loosen the two nuts holding the m.c to the power booster, some times you'll see it in there, look on the inside of your tires, if the calipers ar leaking they;ll be wet. every one else pretty much covered every thing else, respectfully, bob

I'd check the ABS behind the front seat first. You don't need a lift for that.
Then, jack the car up, take the wheels off, and check the calipers and brake line hoses for signs of leakage.
What else is left? The master cylinder, right?

Also check the brake sensor but if that was leaking you would see it. Mine was leaking so I took the sensor off and just plugged it no light anymore but no leak either

That's a sign the master needs replacing. Kinda like the weep hole leaking on a water pump.

Might have an internal leak , replace master ASAP !
