Brake master unit replacement

Thanks John, Vernon Gregory told that he has never seen unit like this. He added that he has purchased over 200 Ercoupes and Alon but no Mooneys...

You might try Vernon Gregory for parts/info.

Thanks Michael for the tip. The part for the Ercoupe looks different however I have asked Alpha Aviation and I'm waiting for their answer.

Take a look at the Advertisers folder and look at Alpha aviation. They have a master cylinder upgrade/conversion

Hi all,
I have got a brake master unit failure on my M10. Since I don't know whether it is a M10 specific item I am posting my question here:
my mechanic cannot find any replacement to the Brake Master Unit P/N SBC 9201-1 made by "Gerder Product". Univair has not. The mechanic has replaced the seal but it seems that the problem comes form the inside of the cylinder whose rubber coating is damaged. He is now asking Aircraft Spruce as a last chance.
Do you know where elsewhere we could find this item? Did you face this problem in the past and find a workaround?
Thanks a lot for your help!
Laurent
