Rear brakes smokin'!!

[Hatman]

On I 95 north of Baltimore. Very heavy 60 mph to zero and back to 60 again, over and over and over. Started smelling something hot and the TPS fired off on both of the rear inner duals being over temp. Thought I saw smoke so I pulled over at the next exit. Indeed. Smoke coming out of right rear wheel wheel. Tire temp not too hot, no visible oil or fluid. As best I can tell it's coming from the rear brake shoes. Let it cool down for 20 minutes and have now driven to a Flying J for dinner and give them a chance to cool. Any thoughts on the cause? I was just at Spartan and they didn't uncover any issues. What proportions the front vs rear braking in these? Any other words of advice?

Two thoughts.
1-Dont be in such a rush.
2-Could be your rear brakes are doing all the stopping.

Leaking axle oil would cause the smoke but would not cause the temperature to rise, as shown on his TPM.
I would guess that you have something that is causing the brakes to drag. Maybe an emergency brake cable too tight or something else that is applying the rear brakes only.

That was one of my first thoughts, but as my post noted - no visible oil or fluid.

Could be possible the rear hub seal leaking oil onto the brake shoes causing the smoke, look under the rv on the backside of the brake backing plate and you may see some oil residue...check out the other side it will probably be fairly clean with oil seal not leaking or brake not smoking...
