Velosteel coaster brake problem -

hello,

i've got a rear wheel with velosteel coaster brake hub that has a problem i've never seen before. let's see if i can explain it. at random times after braking, the distance before the hub engages to drive the wheel is quite long. sometimes just shy of one crank rotation. i already disassembled and cleaned the hub. so last night i took another look, thinking i might have botched assembly, but it looks fine.

the park tool website says:

The cluth jams into the hub shell to drive the bike. With use the knurling on the end of the clutch will become worn and smooth. This will cause the pedals to go further around before the clutch finally engages and drives the wheel.
only that the hub in their picture differs from velosteel. so i'm wondering how that might apply here. also i'm wondering if the clutch were worn would the distance be consistent every time? for me, the "forward freewheel" occurs once after about 3 or 4 times braking. the rest of the time the hub functions pretty normal.

disclaimer: i'm not riding this hub and just curious about the problem. advising to buy a new wheel is not necessary

thanks.

apparently the clutch rollers are worn. bikeguy has a nice walk through also as pdf!

he says:

These are the clutch rollers. If they are worn, your hub will not engage drive reliably and may slip.

Kogswell recomended lots of traditional coaster brake grease for these. Elegant Wheels (bikeguy) sez just a little bit of light grease or you may have trouble with engagement.
