re: Brake Fluid and the kind of driving we do
I was very interested in this thread and comments on new 5.1 brake fluids out there.
I guess, I forgot about the diversity of the members of this forum...
Good brake ducts and cooling can do very well with Dot 3 or 4 fluid on the street. There are very few places in North America where any kind of responsible road driving would need more...
Track days and AutoX may need better. AutoX mostly because of heat soak (that what boiled my fluid a long time ago). Getting too many runs in is too much of a good thing!
Running a tight track like Toronto Motorsports Park (Cayuga) puts a lot of heat in the brakes, with little place to let them cool off (compared to Mosport). I run 1.7g's in corners with close to 2g under breaking, hit 135mph on two short straights. All of the above with limited aero. I stand on the brakes hard 7 times a 1:15 lap... Hence, I am a little fearful of switching to anything less than SRF...
