As the title says, I've got a set of these calipers and masters used (from a 2003-2005 749/999) to go on my 900ss. I'd like to rebuild them with fresh seals first. Does anyone have a source for a rebuild kit, or even just the exact model number for the calipers? And master cylinders?

And, does anyone have a picture of how the brake light switch is supposed to look on the brake lever?

I believe this is what you are looking for in regards to the calipers. I have not found a source for the master.

KTM sell repair kits where Ducati often fails. And for better prices (at least in .de / .at).
The early 990 SuperDukes run the same P4 brake callipers.

61013019100 are the piston seals, 27 €.

Thanks - ordered the kit from powerhouse UK. I believe i got a rebuild kit for a different set of brakes from them years ago actually.

Now to find a kit for the masters... They seem to work ok as is anyway, at least as far as I can tell on the bench, but those rubber bags that protect the piston rod are torn.

Don't waste your time, they're not available as a service item, it's been covered many times (happy to be proven wrong though......)
The brake light switch is a tiny micro switch that has two pins that press fit underneath the M/cyl and the lever has a spring steel tang that depresses the switch when pulled.
The clutch safety switch is exactly the same.

The plunger boots are (nice to know!) but while KTM offer caliper kits I don't believe anyone offers M/Cyl kits
Sorry, I thought you were talking about the dust boots :)
I wouldn't be surprised if KTM (or possibly Aprilia) did offer something, just figuring it out would be the hard bit. I think the older Super Dukes ran a PR18 m/cyl from memory....

Nice! Good thing everyone around here is a KTM dealer so those should be easy to get

Gotham Cycles sells some master cylinder repair kits, as mentioned not all of them are available though. I would try contacting them. If they dont have what you are looking for try finding a local gasket and seal manufacturer. When I was in manufacturing Nashville Rubber and Gasket used to make custom seals and gaskets for us all the time.

Just spoke to Gotham and they also can't get rebuild kits. They said they tried to have some made but didn't have any luck. I may have to just throw the new dust seals on there and call it good
