Re: B50 hydraulic drum brake

I hate to be the one to 'piss in the porridge' here. I see the rubber seals deteriorating in a few years, the brake fluid soaking up moisture, thus requiring frequent brake overhauls, just like I used to do on a 1957 Plymouth back in the 1960's. Meanwhile, the front brake cable on my September 1971 ...

Maybe if you borrowed Scootin Newton's electric starter, that might get it going. Of course that would mean pushing your BSA over the ocean waves to the surly heights of Montana. But, that is something we have all done at one time or the other over the last 50 years or so.

No, my friend, Cocker Cox. The ring gaps were set in a line by the boys on the engine line at BSA during the initial assembly. Had I taken it back to the dealer prior to the 6000 mile and/or 6 month period, repairs would have been for free under warranty. Or, so I like to fantasize.
