GRiSO front master cylinder seep

So, my 2013 GRiSO's front master cylinder is weeping and sadly I found out they don't make rebuild kits but want to sell you a brand new one for $345. The sign of the times. Has anyone out there rebuilt one? There are supposedly rebuild kits from Australia and the UK.

Does one just pony up the money for a new one or buy a new Brembo radial for cheaper than buying a new Moto Guzzi replacement?

Thanks

There's a used one on Ebay Uk for £79 (and the £ is weak against the dollar) and a few in Irtaly and Holland for much cheaper than $345. You could ask the seller if they're willing to post to the US.

Linky for the UK one: [You must be registered and logged in to see this link.]

-or you could contact Brembo or get a shop to rebuild it?

Found a rebuild kit. [You must be registered and logged in to see this link.]

and here's a 13mm kit (you need to check the size on yours) [You must be registered and logged in to see this link.]

Kits are sometimes available, mostly out of stock. Get a know good 2nd hand one or simply spin for ma new one - that way you'll know it's good.
