What is everyone using for a replacement rear master cylinder for the 400s. Are there any replacements available or one from another model that can be modified. I tried a rebuild kit but the casting is pitted and it is leaking.
Thanks
Not bleeded out yet but I got one from hvccycle
Modern replacement
I dont think HVC offers the rear master cylinder any longer. I dont see it on their site anymore.
I have been looking into Chinabay MCs. I was successful in adapting one to a '79 CB750F. They often have very poor desciptions, so it is difficult to see which might work. If you should go that way, you MUST disassemble it, clean thoroughly and reassemble with brake fluid lubricating the seals. Many come with swarf and dirt inside, but cleaned up work fine.
I was gonna us these guys to have it resleaved, but I ordered the rebuild kit from YamBits and it worked. It comes with a new piston
