Experienced it firsthand today for the first ever in any vehicle. I was rather surprised to see that the brakes don't gradually go, but all at once. Took about 20 minutes of being parked for the brakes to return to 100% normal.
I have done a ton of work to the motorhome in a year. Was surprised this one snuck up on me. Changing brake fluid is now on the short list.
I'll share any additional info I learn about my case in particular as I work through it.

Re: Boiling brake fluid
Barry,I had that happen to me on my work truck. Ford E350 dually. Overheated them coming from a job in a mountainous area. You only need to experience it once to know not to do it again. I'm a lot more careful now on down grades. Use the transmission and stay off the brakes as much as possible. Rod

Re: Boiling brake fluid
BarryBarrbhhfchhggvn Barry , it's on my list too. I'm going to use Ford High Performance (dealer item) brake fluid. Has a higher boiling point. Somewhere around 500 degrees versus 300 for my current Dot 3. Gonna try and pull it through each wheel with a vacuum pump. Take care

Re: Boiling brake fluid
Read the Dot3 containers carefully.
Some list both NEW and HYDRATED boiling points.
I believe most have a new boiling point of around 500 degrees F
I believe most have a hydrated boiling point of around 278 degrees F
Yes there is some variation in new boiling point and have also heard that the Ford fluid is one of the best.
But, big issue is to keep relatively fresh fluid in there, as the difference between boiling point of new vs hydrated is the real issue.
Change fluid every two years unless you live in and only use the coach in desert areas.
A gallon of brake fluid to flush and fill is noise level compared with loosing your brakes!

All these brake issues are spooky to think about...not good. Jeff.

Re: Boiling point (was: Boiling brake fluid)
Actually, these brake systems are pretty easy to keep maintained. Or, I guess, easy to neglect and run into trouble.
Biggest issues are :
1. Change brake fluid every two years (one gallon of brake fluid and one hour of pretty low tech labor)
2. Clean and lube the brake caliper slides with caliper grease. Only issue here is that you have to pull the wheels to do it. Once the wheels are off, about 10 minutes with fine sand paper, wire brush and a small amount of caliper grease. Every two years-- more if you drive with salt on the road, less often if you drive it weekly.
Neglect either of the above and look forward to spending big bucks when things go wrong.

Re: Boiling point (was: Boiling brake fluid)
Mel,
Read through that brake fluid paper.
Two points stuck out (direct quotes from the paper):
"Please remember that the specifications are minimums...."
So, as posted earlier some, such as Ford's DOT 3 exceed the minimums.
"One last note on the DOT ratings: Systems designed for a particular type of fluid (especially prior to the wide distribution and use of DOT 4 fluids) should continue to be filled with that fluid. For example, in a car that was delivered with DOT 3 fluid, the internal components of the system (seals, brake hoses, and fittings for example) were specifically designed and tested for compatibility with the chemical composition of DOT 3 fluid. Because the DOT 4 grade fluid typically contains a different chemical composition, compatibility of system components may be an issue."

Good point.
Mine now has DOT 4!.... (time will tell).
