No I'm not confusing anything. You read a definition of glazing and believe it only applies to high heat situations wear things melt. If you lightly drag two items together, they build heat, but not always to the level of melting things. The light application of brakes causes a slight heating issue and will polish/glaze the brakes. After this occurs, dust gets between them and cause the squeal.
Some day, take a look at a freshly turned brake rotor or drum. They're NOT smooth, because they're cut with a machine. Put ten thousand miles on them and they're as smooth as glass. This is wear and glazing.
You're having a difficult time understanding this because you're laser locked on one definition of glazing.
Here is an example, maybe not a good one, but you might be able to relate to....When you buy a donut, you can get plain or glazed. What does that mean, one is just a rough cake surface and the other has a light glazing of sugar that's not burned on/on.
Many definitions of glazing...here is just one...."to lose abrasive quality through polishing of the surface from wear". This isn't a difficult topic, you're just being too literal!
