Just wondering if new rotors and pads take a while to brake in. I have a 2004 Cr250 and I Just got a new cheap e-bay rotor that came with pads. The rotor is thicker than the oem one. It works horrible on the test ride down my street I could barely get the tire to lock up. Doesn't grab hardly at all. Will this get better as the brand new rotor get broken in?
