Bled brake system using oil can to force hydraulic fluid through system. Several bubbles disappeared by pumping brakes and forcing additional fluid through system. Added oil to Rotax using factory instructions for purging the system. The oil tank is filled and pressurized to ~10 PSI. One plug from each cylinder is removed and the prop spun until oil pressure was observed in the Skyview monitor. Pressure up to 42 PSI observed. Plugs replaced, sustem "burped" and oil level topped off.
