A word about brake fluid.

xxx recommends Castrol SRF or Motul 600 due to their high wet boiling points. All brake fluids absorb moisture, some faster than others (except silicone which is not recommended for anti-lock brake systems). Castrol SRF resists moisture contamination (non-hydroscopic) more than any other fluid we tested, therefore change intervals can be greatly extended. This reduces the effective cost over a season of racing. Many drivers say that they can run the same fluid all year long with only bleeding off the fluid in the calipers for each event. This way a can or two will last all year. Other fluids (hydroscopic type) require additional flushing of the system for each track event to maintain the lowest percentage of moisture and the highest boiling point. For cars over 3000 pounds on high speed road courses xxx recommends brake fluids that do not fall below 400°F wet boiling point.

Cool Craig

excellent info !! thx.

SRF is around $70USD! Motul is less than $20.

I didn't pay $70 bottle for it...only $48 per bottle. Still very expensive...I plan to sip it like a fine wine after I bleed my brakes next time. I went to the SRF after my stock brake fluid boiled over at a 100 degree track event.

I have Motul in my race car. Both are good.
