Clean out shavings and reinstalled. I went fr short drive went great. I then drove again and was ok. I tried the ABS and found nothing wrong. I have drove around twenty miles so far all good. TYhe onlt thing idid do that needed to be done was completly bleed all the old fluid form the system and replace with synthetic fluid. It was full of rust and small black stuff.
I also found out that the vavle can be bought with a new master cylinder from most parts places.
Thanks for the update and fix.
