Vintage brake shoe delamination was created by hackman101

Since there is a concern about the pads coming off the backers at a most inappropriate time, when replacing, are there brand new shoes out there for these old bikes or only NOS? It seems NOS shoes would have the same issue? Presumably because age is the culprit.

Just to be sure, I need to stay away from NOS? I seen many listed as brand new, but further reading it mentions that it is NOS in many ads, eBay for example.

"Buy new from Yamaha."

+1

Part numbers have changed over the years (Yamaha's term is "supersede"), but sites like CMSNL and Partzilla should have the current part numbers.

Think they come off from being damp & starting alloy corrosion. Never thought about new old stock but if they look like new & no sign of corrosion i'd be happy to use them. Corrosion is very obvious when it happens.
To edit--Although now i think back, i had a rear lining come off a yamy U75 scoot 30-40 years ago on my sister inlaws scoot so just damn lucky it was me riding it down the road as locked the rear wheel solid. May have been a locally bonded shoe we used to get done but never had one fail so not sure.

I just installed a pair for the fronts from KDI. They installed with no issues and came with the springs. I would have no issues recommending them. Only one ride under my belt but so far they work great. Shipping was cheaper and faster than Partzilla usually is though I think he's in Long Beach so a short ship to the SF Bay area.

Formula:

1. Buy new vintage bike part currently still available from Yamaha
2. List it on ebay as "NOS" and/or "rare"
3. Sell it to an unsuspecting buyer for a good profit because they never bothered to check and find out part was readily available new.

Happens all the time.

Would the hub and pads from way back then, be contaminated with asbestos? You know... clean up the components with compressed air scenario... Getting up in age, don't need to hurry the ending..
