Morrow Hub Rebuild Help!

Can anyone tell by photos of something is worn? I have very poor braking.

you should probably get one of these from Scott.

I believe they are a little less if you get them directly from him.

The other option is to cut new groves into the shoes, I have seen this done successfully and unsuccessfully.

Basically, scoring new groves into the shoe, helps the brake work better. I replaced the brake sleeve in mine, along with all of the bearings, retarder spring, and clutch ring.

Thanks very much for the help! Awesome resources.

What are you using for grease in your hub? If you used a grease intended for bicycle brakes or white lithium that generally will work well. If you used an automotive wheel bearing grease that could be your reason for poor braking. Modern wheel bearing grease is so good at reducing friction that it can make coaster brakes nearly useless. If you used automotive wheel bearing grease in your hub, at the very least, clean the grease off the brake shoe hardware and from inside the brake hub shell then replace it with white lithium or any other grease intended for bicycle brakes which has fewer friction reducing properties.

I usually use an all-purpose Park Tool grease, and add a little oil as I'm closing up the hub. I've done 20 hubs or so without issue, but most are ND and Bendix. I just built a second set of wheels with a Morrow hub and it brakes just fine after the rebuild.

Do you have another, preferably brass brake shoe assembly in good condition that you can try putting in instead?

I'm looking to buy one.

Kevin,

Scott has some of the brass ones, just get in touch with him.

It also could be that the axle

end assembly- cone, spring, retarder washer and axle bushing have moved away from the brake sleeve assembly. After assembling first parts ( pic 1) slide brake sleeve over axle, ( pic 2) the gap should be 1/32 - 1/16” max. If not, then the axle assembly should be tighter together.
