I have been recently upgrading my PA18-A, 135hp 1984A and because I added 31" Bushwheels I installed new Cleveland wheels and double puck brakes. This nessitated up grading the Scott master cylinders. I installed Steve's Aircraft booster brakes with reservoirs. They mount very quickly in the existing Scott actuators. These master cylinders are phenominal. And the good part is I don't have to keep adding fluid. Another bonus is that don't have to worry about the brakes locking up because the master cylinders got hot (cabin heat) and the oil expanded. If anybody else out there has installed these brakes, let me know how you like them. Mike, Shady Cove, Or.[/list][/code]
