Brake fluid protocol
This question is for the racers out there.
What is your protocol for checking brake fluid at the track events. I know many will bleed and use racing fluid but how do you monitor temps mid day to make sure the temp is not to high going into a session. I had a total brake failure in my second session from boiling the brake fluid on the first straight away. I do not want this to happen again. What can I do to monitor this in between sessions?

What fluid were you running? With a solid 40-90 minutes between most HPDE sessions, your brakes should be relatively cool by the next time on track. An early session failure like that sounds like you boiled them in the previous session and had air in the lines for the subsequent 'trouble' session.

Between two Vettes, a C6 GS and a C7 Z51, I have tracked Daytona, PBIR, Sebring, and Road America, I used Motul 600 in both and never had a single issue with boiling the fluid. These were all HPDEs where you run four 30 minute sessions per day. I did get a "service active handling" light once on the GS on day 3 at Road America due to the brake fluid reservoir being low from brake pad wear. A few ounces to top it off and the CEL went away
Also, it take 2 pints of new fluid to completely refill the whole system during bleed/flush.

Hi John,
What track were you at out of curiosity?
You might want to post this question in this thread in another forum section - lots of braking experts and vendors there.

I just would like to know what I can do to monitor temps between sessions as a precaution next time.
