Brake Pedal goes to floor
Thanks Bill! it indeed is more time and money consuming to have this hobby as to have it back in the continent where these cars were originally built!
so as far as the update.. it finally arrived! and i have pictures! (ill keep it short)
new master cilinder did the trick.
full braking power! so the diagnosis was correct :)
after having taken off the old master cilinder, it started leaking from the front brakes hole.. and not the little bit that comes out from where the line screws in, the entire front reservoir drained on the table till empty (wich i didnt completely let drain out all over the place ofcourse ;) but it wouldve. so that also told me that the front brake part of that master cilinder was indeed not good anymore.
