Recently picked up a 1982 GPZ550 which has been sat for a while and wanting to get it back on the road. I'm currently tackling the brakes and the rear brake master cylinder is very corroded and rather than rebuild I was hoping to replace but struggling to find one and most suppliers/dealers I've contacted have trouble sourcing parts for a bike of this age. Any suggestions on where I might be able to get one? Good aftermarket units to try? Other compatible models? Any info would be great! Based in the UK.

I also ran into the exact same problem with my 84 ZN1100. I searched everywhere. I ended up honing the bore and modifying a piston to fit. It was a lot of work. I looked at Chinese rear brake master cylinders, but do you really want to bet your life on a $26 item that your life may depend on? There is a reason why an OEM master cylinder costs upwards of $300 (if you can find one).
At least in your case the GPZ was a far more popular bike than my ZN and the odds are better that you can find NOS or a used one. The GPZ is a really nice bike and in my opinion worth spending some bucks to get it back on the road.

I got the rebuild kits for the calipers from there, however they don't do the master cylinder. Cheers though
Yeah not proving very easy to find one! Was hoping there might be one from another model that was more readily available that would fit.
