Vent screw M10
In the older BMW R1100 and BMW R1150 models, a so-called filling/ventilation interface was installed on the front brake instead of a normal vent screw. It is difficult to bleed through the filling/ventilation interface and the parts are easy to break. This vent screw can be installed as a replacement.
