I've got a sturmey archer hub with a drum brake (model ABC) that needs the brake mechanism replaced...I've often seen it referred to as the "Pork Chop"...its missing most of the parts.

Will a modern Sturmey Archer pork chop work in a vintage hub?

I've got both a modern Front hub and a vintage Rear hub with the drum brake, and the pork chops look pretty much identical. I'd actually be a bit surprised if it didn't fit. Anyone have experience with this?

If it looks like it'll fit, why not try it on? Too much of a mission somehow?

Yeah it is a PITA to try it myself or I would have.. The modern sturmey hub is hooked up and installed, Its not a massive undertaking to take it off and take the hub apart, but I figured I'd ask here to see if anyone's tried it before me.

All the 70mm shoes are the same...no matter what part number they're using. That's all I know.

Is this the hub?



I think they should work with the newer shoes. What's wrong with the brake mechanism?

I've had several AB hubs (are you sure it's ABC??? 'C' usually denotes coaster brake in SA shorthand), and none of them have really robust brakes. It didn't matter what I did to improve it, from roughing up the pads to scouring the drums. At best, these brakes help create drag, but that's about it!

Interesting. I've always found my SA drum brakes to be more than adequate. However, I have found that brake levers can make big differences in braking performance. Older non-aero levers seem to work better than aero levers, IMO.
