Do parts wear out in Coaster Brake?

I am looking at a Shimano Nexus internal 8 gear hub with coaster brake.
Are there brake parts inside that wear or is the braking accomplished with gears?
How does the coaster brake actually work?
Thanks,
Hbob

The old Simplex and similar coaster brakes like we had as kids had brake shoes that expanded against the inside of the hub when you forced the rear cog backward. These parts would wear. But then, whether its a brake or the gears used to stop the bike somethings got to wear.

It takes quite abit to wear out a coaster brake.

Looking at the Shimano site, there is no listing for replacement wear parts for the
Nexus coaster brake hubs. So I assume it is not something you replace often?

I should have added that, as kids with coaster brakes, we wore out many a tire by skidding everywhere but never had brakes wear out.

I agree. Wherever friction is involved there's going to be some wear. But I've found that regular, consistent maintenance - including cleaning and lubing - keeps coaster hubs running for YEARS.

Not necessarily. They may not make the replacement parts available so you have to buy a whole new unit! How many times have I heard, "Oh, that isn't worth fixing - just buy a new one!"

I have replaced brake shoes in coaster brake hubs, they do wear, but very slowly in most cases.

Yes coaster brakes can wear out. I've replaced many brake shoes and brake springs in E-110 hubs. Granted, I manage a rental fleet of 450 beach crusiers that all use the same rear hub and get rode into the ground.

As for Shimano Nexus, any part will wear out. I don't know if Shimano sells rebuild kits for these or not.
