Hello folks,
I noticed after a ride today that the rear brake light on my 350 Saturno was sometimes sticking on, well, I didn't notice, but my friend following me did!. It seems the rear master cylinder is sticking a bit. before i strip it, does anyone know what diameter it is?. Do I buy a generic made in the east replacement?, do I try to get a repair kit?, if so, is Uncle Bob the best bet?. Finally, is it the same as another bike?, looks very like my Ducati one.
Thanks in advance
Alan.

I believe it is a standard Brembo piece. Measure between the mounting holes to help identify the correct item.

the original diameter should be 13mm
As far as i know there is a unusual distance between the fixing screws
50mm instead of 4mm like on several other italian bikes.

Overhauling kits did sometimes not cure the problem.
The inner parts tend to rust

There is a Brembo cylinder available with 11mm / 50mm
Also a Nissin 12,5mm /1/2inch) could be made fitting

ciao Joachim
