Hello Rob, my MM for the Super Dimona specifies DOT4 as break fluid. So does TOST which also is a Cleveland break. It is not specify DOT 5 that you might refer to and is silicone based (not DOT5.1 which again is glycol based) . I would not call DOT4 or DOT3 water soluble. It is hygroscopic and accepts to accumulate the humidity from the air but water degrades performance and boiling point. This is why break fluid is changed regularly or checked for water. regards Konrad

Interesting. I didn't think the rubber bits would go OK with a water/glycol based fluid. Make sure you label the reservoir very clearly what type you are using. If someone adds the wrong type you will get a horrible mess! regards Rob Rob Thompson 0429 493 828 (Please note that my new email address is [email protected]) On Sun, Jun 24, 2018 at 9:26 AM, Michael Stockhill <[email protected]> wrote: I believe the service manual specifies automotive type fluid, likely for the motorcycle type master cylinder.
