Not ABS related. One of your calipers is not clamping as hard as the other. That could be a caliper problem or a little air in the brake line.

I would do a complete flush of the brake fluid first. Use the blue stuff, it is DOT4+, which is what you want and you will know when the new fluid is coming out of the line. Do the rear brakes first, then the front.

If you had one broken ABS line, I suspect you have more problems. Your best bet is to get a computer readout from the dealer - it will give you specific reasons.

BTW, if you work on the car, the ABS will not turn off until you go over 18mph as it does its self check. If it goes out after you pass 20mph, all is good.
