    Default Brake Master Cylinder Problem

    I'm fitting my Accossata M/C onto the new GSXR and hit a problem. The rubber tube from the standard M/C is 8mm. But the new M/C accepts a 7mm pipe

    I fitted it onto my 2009 and 2013 model somehow. They also have the 8mm reservoir pipe.

    I'm stumped what to do. Wish I could remember how I did it before. I had to take it off the 2013 model to get it through the ITV (MOT) as it has no brake light.

    Heeeeeeeeeeeeeeeeeeeeeeelp

    Surely 7mm bore would stretch to 8mm? I'm taking it this is just from the reservoir to the master cylinder ie not under pressure of course.

    Warm the 7mm pipe up and push it onto the 8mm fitting or buy a resovoir with a 7mm fitting or just use a piece of clear hose as a resovoir.

    I think you're reading it wrong.

    The fitting on the Res is 7mm and the pipe is 8mm... so it just falls off?
