Trouble is, most shops are manned by 19 yr olds that don't know a rotor from a shovel and will measure it and say - warped, when it is actually deposits. Poor pad run in/bedding in.Quote:

Disc brake - Wikipedia, the free encyclopedia
Often uneven pad transfer is confused for disc warping. In reality, the majority of brake discs which are diagnosed as "warped" are actually simply the product of uneven transfer of pad material.
Uneven pad transfer will often lead to a thickness variation of the disc. When the thicker section of the disc passes between the pads, the pads will move apart and the brake pedal will raise slightly; this is pedal pulsation. The thickness variation can be felt by the driver when it is approximately 0.17 mm or greater (on automobile discs).

Is there a way to "clean" the extra pad material off without damaging the rotor? I believe they are s softer type metal correct?Quote:

I say go find a machine NOT manned by a 19 year old kid :p
lol gotcha. Ok so if I have the vibration now with current pads, simply swapping them out and bedding properly will not work the greatest? I should get them machined down (Not by a 19 year old) and then bed them properly with new pads. Or just bed them with current rotors untouched?Quote:

If you want a pad that will work pretty much no matter what you do, get Carbotech AX6's. They dust a bit but have good cold bite and will work to the point which few will ever reach on non R-compound tires. Titanium backing plates are a good idea to help to not melt the dust boots when playing hard.

Ok I will make sure to get the rotors machined. I ordered Carbotech bobcats (ordered before I saw that post), I Don't suspect I will be doing a lot of heavy track use until I get everything together on the car. I would like to just get everything in working order before I really start beating on it.Quote:

Edit: scratch that got the AX6 pads instead. Also the guy I spoke with at IPS told me Carbotech pre-beds the pads/rotors now (as of 6ish months ago) Good idea to do it anyways?
You'll be happy with the AX6 and the Carbotech rotors. I had un-slotted Carbotech rotors and they were fantastic.
Yes, it's a good idea to bed the pads/rotors still. Plus you'll get a feel for your new brakes ;)
I would still bed them in to be sure :)
Great thanks for the input guys! Going to get the other set of rotors machined down just in case but hopefully this will be the end of this trouble :)
