I bled the brakes over the weekend. All the 20 year-old Castrol SRF that came out was still crystal clear. Amazing stuff. It's DOT 4 with the highest dry/wet boiling point (594/518 degrees) you can find.
I remember back when we were racing and I tried various brake fluids, you had to bleed the brakes after every run because the fluid would boil and make the pedal spongy. After I switched to the SRF, you could go the whole day of racing and wouldn't have a problem til the end of the day.
