My rear brake reservoir is leaking from the sight glass. Looks like the o ring blew out as I can see it sticking out on the side. 2009 Txc 250. What's the best way to fix this? Thanks for your help. Wolf
I've never taken one of these apart, but it appears that you will have to remove the plastic window and reinstall the o-ring and carefully reseat it in the master cylinder body. I'm pretty certain that it is just an interferance fit. I looked through my shop manual and it's one of those things not addressed. You may be able to find some information on a Brembo brake system web-site, I'm thinking that's what yours may be.
