Fore brake differences

[mike]

What are the differences in a prewar and postwar Schwinn pork chop fore brake?

40-41 porkchop same as postwar but has the cage type clevis. 37-39 totally different - larger too so one won’t work on another.

I've been working on an article for the Schwinn brakes and it appears to me all the post war brakes are all large flange (high/high) hubs. The pre war high/high generally have Pat'd Pending ('41) on them. I have heard some people say there is a pre war high/high with no PP but I have never seen a difference. My thought on this is that the non PP hub was introduced before the war as well just like the non-script brake levers which were used post war as well. As far as I know all the high/lo hubs are pre war. V/r Shawn

Edit--I guess Eric was posting at the same time. So evidently clevis is the 'tell'.

Hi Lo's seemed to be on the lower priced models,dx,ladies and men's. Have seen them 1940,41...latest I've seen any drum was on a early defense model,1942,Henderson badge b107. Painted truss rods,fender braces,no light,rack,tank,had a high flange drum,that actually stopped,though.

The hi/lo style introduced in 40 was still around postwar, it’s in the 48 catalog for sure. I have never seen a non PP hub on an original 41 bike but that doesn’t mean they don’t exist. Happy to proof your article, lots more variations than many realize.

I'll certainly take you up on that! I learn something new every time I touch this topic. V/r Shawn
