just aquired a 1960,s Schinn... love it soooo much , your illustration on how the breaks work is most appreciated ...
The Bendix 70 hub was introduced in 1970 and replaced the previous "red band" hub.
Have you thought of doing an expose' on the 2 gear back axle that Bendix came out with in the early 60s. I occasionally see one of those old bikes and wonder if it was secured by patent and if it's expired, still in production anywhere, et cetera.
Be sure to put grease on the brake shoes of a Bendix Coaster. I once decided to instal “power brakes” on my Coasterbile by only putting grease on the bearings and actuator screw. I washed out the entire assembly with gasoline and dried all the parts. When I rode the bike it seemed to work fine until I lightly applied the brake. The rear wheel locked up tightly and I took an instant spill over the handlebars. Next, I took the assembly apart again, lubed it properly, reassembled it and everything worked fine.
Yes. Absolutely. And it is better to use high temperature grease. Also, many old coaster brakes have a cap on the hub for oil. You can flush out the dirt with something like Tri Flow and then relube the hub with a thick oil.
I just bought a "Columbia Roadster" girls' 26" bike at a thrift store for $2.50. Nobody wanted it at $10. Of course, the Bendix 70 doesn't work... You have encouraged me to open 'er up and fix it.
All the grease inside the Bendix is probably all dried up. I have fixed many of these and they end up working perfectly. Hopefully, that is your case as well. Accessing the diagram of the brake on the Bendix site also is helpful. I also did a video on how coaster brakes work but there is plenty of others out there as well. https://www.youtube.com/watch?v=inO1ba3hwqQ
