I'd post a giant picture of one, with links to some random internet spam, and maybe a topic where someone once asked a question relating to the doseur. I could even post the Cit part number, the old price and the fact that its NFP, but i'm sure if you've read this far you know what a doseur looks like, where it goes and what it does!
Cash waiting for the right part, at the right price of course.
I'll get the valvers breaks working right if it kills me
NB i have plenty of unknown spares on the shelf, but if i'm going to get into the swear fest of changing one, and no doubt having to replace some or more of the pipes, then i'd like to know i'm putting in the best condition part i can find! And yes, i've bled the lines, changed the flexies, replaced the bleed nipples, ran fluid through as per the workshop manual, including the nipple in the doseur its self. I haven't managed to get anyone to provide stainless hoses though.
