An last but not least, I did some research regarding breaking fluid and the compatibility of Aeroshell 41 with NBR 70 O-Rings that will be put in the wheel braking cylinders. The master breaking cylinder that comes from a Robin DR400-180 has to be operated with Aeroshell 41. The O-ring material needs to be of synthetic material. Otherwise it'll swell up!! At the end of the day I will probably do some sample testing with the rubbers I use- just to make sure.
