No one has any ideas? I thought this would be a place that there would be lots of interaction, but I guess I was wrong. Maybe if I posted what MY thoughts are concerning this problem, and then see if it elicits any response:
What do you think about replacing the 1-2 accumulator piston with a Sonnax pinless at the same time I put in an updated Corvette-style 2nd apply piston? Should do the trick, don't you think? I know they make heavier stuff than OEM-style, but I really don't expect to be pulling a trailer, or doing any off-roading, as it's Mama's car.
Thanks for your response.
