park it for the winter & drive the Beemer
empty all the wood working tools out & I will come get them out of your way.
as for the problem at hand, it sounds like either the master or a wheel cylinder. look at all 4 wheels for signs of wettness. Im trying to remember if you have power brakes or just old "el manual". look at the rear of master for signs of leakage also. I personally would replace all 4 wheel cylinders & also the master as well as all 3 hoses. if one went the rest are gonna be following suit soon. I (& most likely you too) just hope it isnt a blown hard line. if you need assistance feel free to PM me for my phone # & I will be more than happy to help. (remember the timing?)
