According to the 2019 Owners Manual, criteria for replacing brake fluid include:
- If the "the age of the brake fluid is over a month old or unknown, replace the brake fluid before track events and competitive driving." (pg 165)
- "Replace brake fluid every three years." (pg 315)
- If the "the age of the brake fluid is over a month old or unknown, replace the brake fluid before track events and competitive driving." (pg 165)
- "Replace brake fluid every three years." (pg 315)

Brakes fluid replacement
Thanks Norton for your information, my Z06 is not for track, on page 251 the brake fluid is okay on marks, in other words I don’t have to replace it but I will ask the local dealer, thanks again.

Unless this is new technology that is sealed, every car I have been in will allow air in. Brake fluid is hygroscopic so unless you can seal it, moisture will be absorbed. I have a sucker that will empty the reservoir and I can put fresh fluid in. After that, I have a pressure system that will pressurize the fluid into the reservoir and you open the bleeder screws in the appropriate order. Tracked or no, it will suck in air.

Replacement brake fluid
Aklim, thanks for your message, in my 2001 Dodge ,pick up truck, I only change twice the brake fluid because was very dark, not compromised the brake accuracy in all those years , once again, I don’t need to replace the fluid as far as your opinion is concerned , yes, because the reservoir has a little hole on cap for two reasons, allowing the atmosphere being exposed to the fluid and prevent vacuum on it in the other way doesn’t mean in a new car will be a factor for safety .

I know there are millions of cars on the road that haven't had their brake fluid changed in 10 years and they haven't had an issue. However, that doesn't mean the fluid is safe.

Brake fluid replacement
Thanks Bill for your message, do you think I have a issue safety in my Vette, or old truck ? don’t know if you read my story, are you a Corvette specialist or Guru ? I’m not concerned about money, only safety, why I don’t have a warning on my cluster or fill unsafe when braking , appreciate your answer .

Old fluid has a lower boiling point due to water content. Is this dangerous? Well that depends on how often and how hard you use the brakes. In typical daily driving situations, as Bill mentioned, you could likely ignore the fluid for many years with no noticeable performance problems. Towing a trailer, doing mountain runs, track days, etc all would require way more frequent fluid changes. These are your brakes we are talking about... so I would change the fluid every 3 years regardless of how it looks.

Anyone wanna lay odds that this is like another person threating to do something bad to themselves and want others to talk them out of it? Like the Terminator, my hunch is he will be back.
