1975 Kz400-Front brake caliper rebuild

I've got a 1975 Kawasaki Kz400 that I am doing a rebuild on. I'm struggling finding parts to replace the O-rings and other parts for my front caliper. Wondering what websites I can visit to get these parts. Thanks for any help.

Have you tried partzilla?

Yes, I'm searching for any rubber seals that I may need to replace once I crack it open, but cannot find any sites that have them in stock.

No eBay APP ID and/or Cert ID defined in Kunena configurationWelcome to the wonderful world of KZ400s. The front brake caliper seal has been unobtainable for quite a while. Fortunately there is a new source on ebay. I bought one for my '76 KZ400 and it has been working quite well. Not cheap though...

This may not be the one you need. Get the OEM part number from Partzilla and contact Junkboy. He's pretty helpful.
HTH,
Jim
