For all those with leaking master cylinders

[the hat]

I\'ve seen a lot of people mention that there master cylinder is leaking my old white FC and the red n/a both did the same but they are easily repaired

Once you have the cylinder off you will see a curclip that holds the insides in place once removed you should find 2x large o ring on the end of te shaft I replaced this and problem solved



Or even just clean all the gunk off of them and give it a try I was shocked how dirty and gummed up the inside were

What size O ring was it ?

Honestly I can\'t remember as I\'ve got two big assorted boxes of o rings and one of those sizes fitted

Clutch or brake ??

ohhhh good to hear ... that looks like a nice cheap fix
