I did the long bolt and springs mod on my RV-8A. However, one of the master cylinders developed a leak on top that required a rebuild. The rebuilt cylinders had enough "return" / recovery to eliminate the need for the springs. Kept the long bolts though. Note that the spring installation was not the cause of the leak; the shaft had deformed which allowed fluid to escape under heavy braking. Hopefully the long bolts will prevent the master cylinder from twisting, and reduce wear on the shaft.
