2001 Mitsubishi Eclipse (No ABS). 300,000 miles (really). Runs great. I put front pads and rotors (new) and the pulsating stops for a month at the most then returns. Not constant but under stress (high speed) it really vibrates the pedal and front of the car. Has been happening for the last 4 years with at least 7 brake and rotor changes. Any ideas? The pads that come off look like they are wearing evenly. ---

Have you changed the calipers? Maybe they are sticking and overheating the rotors. Did you buy good OEM or better rotors, or cheap Chinese ones? ---

What tardis said. You need to make sure that the calipers are not sticking - at the very least clean and recondition the slides. And don’t buy bargain basement rotors - spend a bit more money on those to get decent quality. Some other common errors: - make sure that the hub and rotor mating rotor surfaces are clean and smooth - no rust or dirt globs or anything like that. - find the correct torque specs for your lug nuts and reinstall the tires with a torque wrench.
