Glazed brakes, now what?

Glazed brakes, now what?
Can't say for sure how it happened, but They have been less than desirable since I bought this camper new in '14. Just lived with it since we mostly go on short trips. Going on a fairly long trip and decided to check this out. First, it's not the truck, hooked up to my neighbors 2016 GMC and it is the same, so it's the trailer. 1 of 4 will skid on gravel at full power, idle speed. It virtually has no assist on pavement. I pull the drums today and they are polished like glass. Brake cleaned them to death and no better. Tomorrow will get drums turned, but do I need to replace the shoes? The rig has maybe 5,000 miles on it.

When I glazed the pads on my 1/2 ton truck (due to excessive use of wheel cleaner I think) I pulled the pads off, sanded them down to clear the glaze and slapped them back on. That was at least 50k miles ago and haven't had any issues since then. I also cleaned the rotors with brake parts cleaner. I don't think the brake parts cleaner would have resolved the glaze on the pads.
IMO, if there is still glaze then try sanding them. If that doesn't work, get new shoes. Be sure you don't breath in the dust from sanding.

Was just going to say this. Drums are supposed to be shiny. Just like the surface of the rotor. It's the pads or shoes that can get glazed, and the solution is to sand them until the glaze is gone.

It helps to clean the drums (new or not) in scalding hot soap and water. Then use a clean lint free rag soaked with a non residue solvent like naptha and remove all traces of oil or wax & grease from the brake surface, till the rags come back clean. On installation wear clean gloves and use extra care to avoid leaving greasy fingerprints on the braking surface.
