Hi Wolf,

I am sure the man with the knowledge will be along soon (Moose) but to share my experience of fluid loss on the brakes of my U1000 the seals had perished and in truth the master cylinder itself and the fluid had leaked into the brake booster back along the actuating shaft. If the booster is of similar construction it will have a small metal  pipe on it as an air vent near to where the master cylinder bolts on. Check that for signs of fluid. Sometimes they are extended with another pipe but I believe it should separate from the extension leaving a length of metal pipe about 40 to 50mm long.

Just a though
