It's a good idea to recheck everything for sure. Have you figured your brake pedal ratio yet? If not, just google it and you will find out how, if you need to. The only other thing is, and I don't think this is it. The larger the piston the less hydraulic pressure is built for a given amount of "foot" pessure on the pedal vs. a smaller piston. Drum/drum use to run the smaller piston (7/8"). Call your vendor and ask if necessary.
