Coated Rotors

I often wonder about this. Car manufactures don't have break-in stations placed within an assembly line or a cadre of factory workers that take every vehicle to a track to bed in brake pads before shipping. No new car manufacture has you come back after 300 miles to change out your break-in oil. Now, having said that. I do believe that if you are optimizing a vehicle for a higher level of performance, or a manufacture has a specific break-in procedure. Then yes, worry about it. But on average. Nope. Put it together and break it in just like your daily driving habits. Snake oils and witchcraft be damned.

I completely understand how most think this way, but there are a couple of things to take into account there.
One is that assembly plants don’t bed in new brakes because it isn’t financially advantageous to do it.
There is one good reason for us to do it.
Coming to a full stop and sitting at a light holding the brakes on brand new hot rotors causes the surface of the pads to transfer (bed) material unevenly across the rotor surface.
This causes a inconsistent rotor surface tension, and therefore slightly less braking consistency.
Yea, it’s not something most would bother with but it is a thing, so why not take 15-20 minutes to do it right when replacing both pads and rotors?
I didn’t say he had to do that way, just that the bedding procedure is the right way.:D
