Cycleguy55, The reservoirs are the same size on this master cylinder. I switched ports and there was no difference in the symptoms. Also, I replaced all flex hoses with steel braided hoses so hose flex is not the issue.

Snapier, I have become an expert at adjusting the GM E brakes, so I know that is not the problem.

I re-bled the brakes, operating the master cylinder a few times by hand in the car to fully depress the piston and then completing the bleeding normally, no change in symptoms.

I should buy stock in brake fluid...I'm going thru it like crazy!



Keep the ideas coming, I appreciate them all!
