I'm shocked how little information is available online with regards to this subject.
When I do an image search for "brake glazing" Google shows a lot of rotors as well as brake pads. No pictures of drum shoes (not that I have drum brakes, however). It's very confusing and frustrating.
My current understanding of glazing is that it only affects the pads or shoes, not the rotors or drums.
Does anyone really understand this subject?
My understanding has always been that brake glazing in a Motorhome application is due to being too light on the brakes...too much dependence upon the Pac or Jake brake and very little full engagement of the service brakes.
Also many are unaware that they need to calibrate their automatic slack adjusters periodically to insure that the brakes can be engaged fully.
