Fairly simple as far as brake fluid goes......replace your fluid with some high-temp fluid (Motul, Castrol, Valvoline Syn, etc.) I'd also look into your braking habits. Are you on the brakes for long periods of time or do you hit them hard and late which is the best way to keep the heat down? Three discs on an 850 lb machine should dissipate a lot of heat, I would think.

Options...

you do have to make major changes to the system if you go to the DOT5 types. But you must have other issues with the system you have. Check that you don't have some other heat source affecting your fluid, like exhaust parts or engine parts....seems like that breakdown of your fluid should be affecting your pads and discs as well...:dontknow:

Exactly, my point is, if i can just simply change the fluid to DOT5 or not really. I doubt there is anything with the system appart than i drive agresive. We do have here some mountain roads long for 50-60km with some big U-curves and it hits the bike. That is the reason i was asking about the another, higher"boil" option

The U.S. F3 operator's guide calls for the use of ONLY DOT 4 brake fluid, 16.2 U.S. oz.

Do NOT use DOT 5 brake fluid in your spyder. It is silicone based and will cause you all kinds of problems. They are not compatible.

You really need to look at using the engine braking more and service brakes less. Use a good quality DOT4 fluid, flush and refill.
