Brakes bedding - coated rotors and pads with break-in compound

About to redo my brakes again. Nothing too difficult, mostly time consumption and some patience.

Getting rotors that are coated for corrosion prevention.
Also getting pads (yellow stuff) with the bed in layer.

Would you go bed pads on these new rotors?

My initial thoughts were to:
- Install the new hardware
- Drive normal until the top layer of rotors has been scrubbed off
- Do pad bedding then

My new shoes are below.



For those looking for info, bedding involves getting your brake system up to temp, by normal driving and braking gently to heat them up. Then, you go to about 60mph, and get on your brakes hard (just before abs kicks in) and decelerate until about 10mph (do not fully stop - stopping with very hot brakes can transfer some material onto rotor and bake it in, which can result in vibration when braking, etc).
Then you accelerate back to 60 again and repeat about 10 times. Your brakes will feel like they are fading when you get near the end of process (feel like you have less stopping power - expected).

After that, you drive the car and try not to stop or use brakes so they can cool down. This way, you get the rotors evenly coated with a thin layer of pad material, which maximizes stopping and makes the brakes wear evenly. Each time I do it, my about to be replaced rotors look perfectly flat and very evenly used.

So I allowed the coating to wear off by normal wear, then bedded the brakes. Worked like a charm. All set for now.
