Something is causing my drivers side rear brake to overheat and I
can't figure it out. Everything is new but still troubleshooting.

Book calls for .039 max. run out. I'm running at .030. Flange squareness .0024. I'm running at .002.

I was suspecting the axle but I can eliminate as it is within tolerance.

Any suggestions what is causing my rear L brake to run hot. The passenger side is fine.

I tried completely backing off the adjuster. No go.
The brake cylinder is new. It stops the drum when the brakes are applied and releases it when released. So that's a no go.

I am stumped?
