1 brake heating up?

Since then we have cut 1 wire on the bad wheel. all other brakes work as they should. the wheel in question with no brakes attached is cool.

I have another idea: Perhaps that wheel is carrying a lot more weight. When you checked the temps with the brake wire cut, just how cool was it?

The way I read it, the brake has been replaced three times already. Once as a brake assy, twice as an axle assy.

You may be right, but the way I read the OP was that the axle was serviced a couple of times with no mention of change of brake assemblies. I was doubting that the new axle came with new brakes/hubs, but that the originals were used.

So, point # 8, after the axle work, was the ONLY mention of a new brake assembly I saw noted. I may be wrong.

I'm starting the think @jkwilson has a good point on the out of round hub.

I may be misunderstanding, but have you narrowed it down to the brakes, not the wheel. In other words if you disconnect the brakes on the problem wheel does it still run hot? You can either disconnect the wire or find an area you can drive with the trailer brake controller turned down to zero. Apply the brakes a few times and see how hot the wheel is.

This is an excellent point. Check the hub and bearing.

Also check brake wiring for potential shorts or bad connections that could be causing brakes to sporadically engage.

Good Luck!
