Hi my name is Chris I have a 2005 Winnebago Journey 39f Freightliner chassis with only 19000 miles
Here’s my issue when using moderate to heavy braking we smell hot brakes. Now mind you I am using a properly working exhaust brake on maximum and I am referring to taking a freeway off ramp from say 50 mph approach speed, with a 20 mph turn in the ramp, now that’s only a 30mph decrease in speed and yet we smell brakes.
Is this because of the poor interior to exterior seal on the bottom of the coach floor?

I will also add that I am a retired truck driver that is quite familiar with air braking systems and how to properly adjust for maximum equal braking on all wheels. In my big truck any time I smelled hot brakes were when I was hauling a max load and having to do hard braking. In a big truck the bias on braking is about 60% rear and 40% front, but I have been told that the bias may be different on a coach.
Could this possibly have the wrong bias valve or be installed backwards?
Next time out I plan on using my inferred temp gun to get an idea on how hot the brake drums are getting and how even the temperatures are side to side.

Sounds like a great idea, I check my truck and trailer wheels routinely at stops. Actually it's my wife's job, and it's important. Do they leave a lot of brake dust? Some pads are just 'not the best'.

It seems evident that something is wrong - there is no reason at all for the brakes to be hot enough to smell in that scenario. Could be as simple as a damaged/worn brake pad or a faulty valve. I wouldn't jump to any conclusions about the cause, but I'd definitely get it investigated by a competent air brake tech. My personal choice would be an appointment at the FCCC factory service center in Gafney, SC.
