Dodge Promaster Brake light comes on.

[Oneilkeys]

I am on my way home from an 8000 mile seven week trip from FL to UT and CO. During the trip, I crossed the Rocky Mountains four times and experienced down grades of 6-8% for 8-10 miles. Even though I manually down shifted to 3rd or 2nd gear and used the engine and very little brake, in every instance, after about 5-7 miles of down grade the brake light would come on - even though, in the last instance, I had not touched the brakes for well over a mile. In two of the 8% downgrades,I had to use some brake even in 2nd gear to slow down for the 20 or 30 mpg curves. In those cases, not only did the brake light come in, but I got a message briefly across the dash that said the brakes needed to be serviced. In all instances when I stopped the Travato and let it sit for a while, when I turned it back on the brake light stayed off and I received no more messages. At no time did the brakes “fail” or even feel “squishy”. This is my 5th RV and I have crossed the Rockys 30 or more times (four on my way to Alaska and back. I am used to using the engine as a brake and I do not ride the brakes down any hill.
Has anyone else experienced anything similar?

I posted this on the Winnebago Travato forum and several people came back and told me that this was a known non-problem with the Promaster, I.e. it happens but it does not mean that there is an actual brake failure.

I am posting it here to alert Thor Class B people who have the Dodge Promaster that this might happen to them. If anyone had any more information on this issue, I sure would like to know.
