Are These Hub Parts Worn Out??

[kscheel]

Well, I tore into my Bendix manual 2-speed hub today. Everything seemed to be in great condition except the two pieces shown below. I can't say I know the proper names for them but, what I can say is that one of them looks to have a good bit of wear. Can I get away with reusing them or am I going to need to track down some replacements?

In the part diagram they are listed as part MS-22.

Those are your brake shoes. They will probably work okay. If not you'll have to find another old hub to strip.

Being as one is in good shape and the other a bit worn, I would look harder at the taper on the expanders, as they are obviously pushing one shoe much harder than the other. I'm no expert on these though, but even on a single speed if the shoes looked like that I might check the threading and alignment on the expander. Yours are ms-6 and ms-33. I thought these models had a small spring with a ring and tabs to help everything return to normal after braking but I don't see one in your diagram. Had that been the case I would have said to look at the spring for wear.

Get a Dremel with a narrow silicone carbide cut-off wheel and cut new grooves in the worn pad. Fixed! Gary

I see, brake shoes, that does make sense. A guy on the CABE said he has NOS shoes, if that deal doesn't work out I'll either just cut new grooves or just say forget it and go with a New Departure or Bendix single speed. This 2 speed setup does seem to be wuite the cats meow I thought it would be.

whats wrong with the shoes? they look OK to me, like they are well arced in. do they not stop OK? :?

Well I never actually road the bike it was installed on so I can't say for sure but, I can definitely see myself reinstalling these and having a problem. I don't want to have to pull this thing apart again.
