Some info on brake fluid

general information: note the OEM recommendations.
Why Change Brake Fluid

any brake fluid can boil if you get it hot enough.

We don't assume he has hyd. brakes. He says he has a 38 ft. bounder, not diesel. A gas Bounder has hyd. brakes. Why should he cancel his trip because of brake fluid? Just change the fluid. It is that simple. I am one of those people who goes nuts about people being paranoid in a motorhome. Don't get up underway, Don't drive with the propane on, Etc. We do all these things. However brakes are the most important item on a motorhome. I would ten times rather break down and not be able to move than lose brakes on a mountain grade. A motorhome is a heavy vehicle. Brakes are a friction device. They trade heat for motion. The heavier the vehicle the more friction is required to slow it down. This heat goes through the pad, through the piston, and into the brake fluid in the caliper. As your own chart showed you, moisture lowers the boiling point of the fluid. I am not trying to argue with you or keep this post going, I just can't let someone give terrible advice to other people who might not know better.

I'm not trying to pick a fight, but what you wrote didn't take into consideration the condition of the brake fluid: "I respectfully disagree on changing the brake fluid unless there is an obvious problem with it".

You can't wait for an obvious problem. Brake fluid will pick up some opacity almost immediately, then it looks the same while it deteriorates. Fluid that would not make it down a long grade without fading is going to look a lot like 3 month old fluid.
