Z51 brake burnish or break-in?
How did the brake burnishing process recommended in the manual go for new Z51 owners? I知 planning on ordering a Z51 in February for a May delivery. I値l burnish the rotors with the stock pads, but will likely replace them with low dust pads. Should I do a burnishing process with the new low dust pads?

If your going to swap pads I would not bed the OE pads because you will need to remove that material to bed the new pads. If you go with the low dust Carbotech 1521 pads they do not need to be bed.

Drifting
What the OM means by burnishing is what those of us that track our cars call "bedding". The process causes a lot of heat to be generated, and this heat serves to oxidize both the rotor and pad. A layer of oxide with great friction properties is formed on the rotor. Unfortunately, this good oxide layer is transient; cold pads will scrub this layer off cold rotors, so street driving removes this layer. This is why metallic brakes squeal, and why you can't always trust their performance for street use either. Some compositions will "bite hard" and give you almost jolting performance in a hard braking event. Then, if front is hotter than rears, ABS will activate. Good news, any mud caked underneath the car will fall out due to all the shaking going on.
So the answer to your question is burnish only before going to the track.
"ceramic" pads generally do not need this oxide layer to perform, and braking performance, while suitable for street use, does not provide the "WHOA" you need on the track. Or you may experience brake "fade" if you are braking a lot going down a long mountain. In fact with ceramics, what does happen is if you are stopped in traffic with hot rotors and pads, you will get transfer of pad material onto the rotor where the pads are clamped to the rotor for a long time. This will lead to vibration most drivers incorrectly call "warped rotors". What they really are experiencing during braking is changing friction properties around the rotor causing pulsations.

I highly recommend Carbotech 1521 pads. No break-in necessary. Very happy with mine. Got them from you, Adam.
