Master Cylinder O-ring

*Not sport related*

Although I think the master cylinder from my dCi may use the same O-ring as a 172 etc.

The master cylinder has been leaking on my daily dCi 100 and has now failed its MOT. I have a spare dCi for parts which I've pulled the MC from, however, the O-ring is shagged on that one too and looks to have been dribbling. I was wondering if there off the shelf o-rings you can buy? I will probably have a word with Paul @ @renaultpartsdirect and see if he can suggest anything.

Anyone else had this issue? Couldn't find any previous threads :)

Measure your O ring an PM me the size. I have 2 spare master cylinders with O rings that are good. If I have one the right size I will post it with the brake lines
