Only thing I can think of is that you hooked the wrong lines that head to the back up to the master cylinder or pinched a line in the process.

On that note, why did you bother bypassing the ABS module assembly? Even if it is non functional it at least acts as a junction block and distributes the brake pressure where it needs to go. And even if it's flipping out and randomly kicking on and engaging the ABS system, just unplug the module until you can get it properly fixed and that should stop that temporarily.

Have question as well
I have a 97 4x4 blazer. For the past 6 months, it has occasional brake failure. I put them on, the peddle goes to the floor and the engine revs up, I go through a stop sign. I took it in and they said it was my Master cylinder, then some type of sensor. It still occurred. It does it maybe once a month. I recently had the ABS booster replaced. It is not made anymore so I got a junk yard part. It was ok for 2 months, then, once again, as I go down a hill like a driveway or exit a parking lot, the brakes fail even with controller, the engine revs up and I nearly get into an accident.

There as got to be a reason. Any suggestions?
