The brake system has more or less been replaced, except for the master cylinder and the ABS light will not go off. It went out for about a minute when we were finishing up bleeding the brakes but came back on and stayed on when we backed it out of the gargage.

I doubt the ABS problem is with the braking system. Did you mess with any of the wheel sensors? Sometimes, brake dust can build-up on the sensor, and make it hard to see the encoder wheel. This will set a code and turn on the light.

When you compressed the piston back into the calipers did you open the bleeder? If not that could have set the light.

A 1994 S-10 with ABS brakes??? Few CARS had ABS brakes in 1994… Is this a 4-wheel ABS system or the version that just prevents rear-wheel lock-up?
