I'm after some replacement braktec master cylinder rubber boots, 

I've just got some Jitsie ones but the compound there made of

is two firm and they just keep folding inside out when you use

the clutch. has anyone found any decent flexable ones ? 

Try rotating the Jitsie ones a few times after pushing them into place, I've just fitted one and it kept popping out until I did this to make it seat properly.

which end where you having issues with ? mines from the small 

end not the cylinder end 

Mine was the cylinder, so probably not relevant.
