I checked the archives and found no recent posts on this topic. I am racing an FC in vintage events with LD20 calipers.
I had been using Ford Motorcraft Dot 3 and have learned that I am boiling the fluid when braking more aggressively causing a soft pedal toward the end of the session. I switched to a bottle of Motul 600 dot 4 and that problem was cured the next race.
What is considered the best choice for compatible brake fluid? What are others using successfully?
Thanks in advance
