You may be correct Lance, that they sell whatever is on the shelf at the time. Those were the "house" brands whenever I have been there. Additionlly, I've found a couple of rules, which in my opinion, when followed, will extend the life of rotors. 1-Always use a torque wrench to tighten wheel lug nuts gradually, to the correct torque settings. 1a-Never let a mechanic tighten your lug nuts with an impact gun! 2-Use a burnishing procedure for new rotors and/or pads to allow them to come up to operating temperature gradually. Also, KVR and others recommend that you do not install new pads and rotors at the same time (can't comment). Extreme measures for rotors-cryogenic treatment or vibrational stress relief ($$$)!
