Similar thing happened to me, found the front soft lines would open just enough to apply the brakes, closed off after braking never releasing the fluid. New soft (brake line hoses) fixed the problem after the Tech2 assisted bleed.

What's the proper procedure to bleed the abs with a tech2? Have it activate the abs, then start bleeding the calipers 1 by 1?
Doesn't the Tech 2 prompt you for procedure when you select the ABS bleed?

I'm not sure. I activated it once with my Express van--just to see if it would do it. It did, but I never bled the brakes. I felt the brake pedal pulsate.
from what I was told it does activate the ABS module....My brakes just didn't want to bleed properly. I took to a local small shop that had Tech2 and he said even he had a hard time getting a brake pedal he liked...but they are good to go now.

The Tech II auto bleed is made for dummies. It starts off by telling you to press brake pedal while in neutral/park. Then it tells you which wheel to start off with and cycles the ABS pump for each wheel. No need to old school pump brake pedal and hold. The ABS pump is your inside the vehicle guy. All you have to do is crack bleeders loose when told.
