After two years of research and development, Service Bulletin No. 15AC-WBKIT
Installs a new, replacement wheel and brake kit to fit the Aeronca Model 15AC and S15AC Sedan Airplanes.
These are direct replacement wheels and brakes for the original Goodyear wheels and brakes that came on the Sedan from the Aeronca Factory.
New replacement Master Cylinders that Use O-rings for seals instead of difficult to replace specialty parts.
The torque plate is drilled with multiple bolt patterns which give this wheel and brake kit the ability to fit other models of CAR 03 and CAR 3 aircraft that utilize a 1.5" axle. (Cessna 180/185/206, Piper PA-12/14/18, etc)
