I happen to have/drive/track an F355B. On track I had a pad fade incident at TWS at over 100 MPH inbetween T1 and t2 (pads not fluid as it was less than 1 week old after a complete flush). Pedal pressure remained fine, however retardation went to about zero. After upgrading the pads to Ferrodo DS2500 and keeping fresh fluid* in the car these issues went away even in 103dF ambient temperatures and even with brake rotors hot enough in the pits to roast hot dogs after a 25 minute track session after a cool down lap using no brakes. All of this was done while laping within 2 seconds of the lap record for 3200 pound cars with 400 HP on street tires (not r-compounds). I did/do numerous sessions and have not had another 'event' in many years. (*) I have been using fresh AE SuperBlue/Gold and recognize its limitations as pointed out by Rifledriver. The key on a race track is the freshness of the fluid, less than one day is optimal, less than 1 month is manditory. If you progress to r-compounds or slicks you are placing a heavier burden on the fluid and need to step up the fluid ladder accordingly. However, (my opinion) in no event should anyone try to go more than 1 year in a Ferrari on a single complete flush of fluid. If you ever take your car to superlegal speeds, you really (really) don't want a braking incident to spoil your fun. With stock pads at a track, the pads get up into fade territory a in the first several hundred feet of a 160-60 deceleration event. Having the fluid fade along with (or in front of) the pads is not a recipie for a fun day anywhere on any road.
