Look at 'picture4' in HH56's post just above this one. U will see that the bottom of the 'O-ring" is much more hemispericaly shaped than the DSC08042 pic which is rather flat on the bottom.

I have suspected all along that the compensator port in the rebuilds are faulty. Somekind of RE-fit part from some other source maybe not even auto related nor hydraulic related. If the compounding of the replacement compensator port rubber is wrong then very likely the DOT3 or even the DOT5 brake fluid maybe causing the damage.

We need some more good pics of the compensator port valve pictured in DSC08042.
