Excessive warpage of rotors is most likely a key that your wheel bearings
need replacement....  A sticking caliper piston can do this as well, sticking
caliper should be felt on a hill, it will still drag when foot off
brake........  Make sure you bleed the brakes 1 per year, brake fluid absorbs
water over time, and can wreak havoc on the brake feel and pulsation...
