"Creeper"....It's lovely that you drive the mountains and know all about heat glazing, but you can also polish the brakes by applying them lightly on a regular basis. Your engine/exhaust brake typically drops off at 15mph. Since most RVer don't rush up to signals, they need very little braking to slow the coach to a stop or slow roll after getting down to 15 mph. Many think they're saving those expensive brakes when they're really lightly glazing them. The repair is a high speed run with a few hard stops. You can also use emory cloth to clear up this type of light glazing.
The high heat glazing that you're speaking of takes rotor/drum turning and shoe/pad replacement. There are levels of glazing!!!!
DSDP Don, I thought that polished brakes are exactly what rotors are supposed to look like. Correct me if I'm wrong, but every single disk rotor I've ever seen on every single car has polished rotors with concentric small groove marks when they are used. On my home vehicle, it gets rusty when I don't use it for a while, but after a trip out, it returns to a normal relatively mirrored polished finish. Frankly, I don't see how it's possible for the rotor to look any other way unless there is some serious metal on metal scratching going on.
Please help me understand this. Aren't your brake rotors shiny and mirrored? What am I missing here? Again, this is an area I don't really understand well.
All my research suggests that glazing is a result of over-heating the brakes. How can applying them lightly cause overheating unless you ride the brakes lightly and constantly, which I don't think Creeper is advocating?
The amount of braking needed to slow from 15 mph to 0 is negligible and only for a short amount of time.
