Resurfacing basically new front rotors?

I'm planning on switching my OEM pads out for akebono's pads in the front, I just had my fronts done about 2k miles ago with new rotors also, what I'm wondering is how to go about resurfacing the braking surface on the rotors to have it match up well with the new pads?

You don't! I wouldn't shave any precious amount of metal off of the rotors, they're thin enough to start with. You can scuff them up slightly, if you like, with some emery cloth or Just put them on and start driving. For best results, always start with new rotors and pads.

Here is the answer- http://www.amazon.com/FLEX-HONE-BRAK...lex+hone+rotor

Faster than emery cloth or scotch brite. Load it up in your drill and go. Make sure to also buy the flex hone oil as it needs lubrication to prevent galling.

And never use sandpaper, as the silicon can impregnate the metal and turn into a carbide when the brakes are used for the first time. Carbides are very very hard and durable. Not good for the rotor surface.

PS, when changing compounds, always either replace the rotors or remove the pad transfer layer using one of the above methods. Flex Hone is the way I like to go because it's fast and effective. Resurfacing isn't preferable since it thins the rotor and exacerbates any thermal issues that might exist.

Just put the pads on bed and go. The akebono's are nothing special.

Disagree but feel free to try that approach. Might end up with squeal or eventual pedal pulsation. I prefer to do it right the first time.

Your call.

I have done hundreds of brakes, but tdo what you want. It is not a performance pad. You will not get pulsation either. Just bed them in let them cool and your good to go.
