    Have the ABS autobleed function done with someone who has a Tech2 scan tool.

    It turns out that hydroboost unit had a leak and because rear seal in master was no good, power steering fluid was being pumped into master cylinder. The rubber in master swelled up and lines to calipers open under pressure but collaping and not releasing.
