Hi Ron,
Sorry I didn't see your post the other day. I did change from the McCauley brakes to the Cleveland Kit myself. I am an A&P but as Jim mentioned, it was very straight forward. I purchased my kit from Aero Performance in Ft Worth. When I switched the brake cylinders I held my finger over the brake line and lost minimal fluid. I just bled the brakes afterwards and it worked just fine. In all honesty, it was easier than I thought it would be. I didn't have to adjust the brake line but very minimal to make it fit right on the new brake cylinder. I had my master cylinders out last year so there was no need to do it again. If you have any other questions let me know.
Grant
