Front Brake/Clutch Master Cylinder Rebuild Kit?

I'm checking out another lead, but here is the response from a different Brembo rep...

Hi Blake,

Unfortunately what you are running into with having trouble finding service materials for the master is an issue caused by contracts between the OE and Brembo. Sadly we are unable to have access to any of the service kits for the masters used by Triumph (and by extension, any other brands using these masters).
Triumph can get the service kits but most dealerships will not do this as it becomes a Liability issue and is what we understand to be the reason why the kits are no longer available to us as a distributor.

The only solution we can offer would be a full replacement of the master with one similar to what you have or an upgrade like a Brembo RCS line.

No good news (see below). Looks like the business model is for us to buy entirely new MC every time we want to rebuild the clutch and front brake. Ridiculous!
Beer to anyone who finds an aftermarket source- please.

Unfortunately Brembo doesn;t sell any rebuild kits for ANY radial pump master cylinders. Your only option is to buy new ones, the RCS radial pumps which are different that what you have but better. You would need to grab the full kit of master cylinder, hose/bracket/cup.

What do you have for caliper(s) up front? 1 or 2 calipers? Let me know so I can send you the right links to purchase the right sized master cylinders.

I went ahead and asked him to let me know which "upgrade" ($$$) is recommended and will let you all know.
