|  Pulsing brake issue
Having an annoying brake issue. When I stop normally, the brakes pulse. Not feeling it in the pedal at all but the whole car pulses under normal braking. There is a slight squeal also. I can get rid of it for a short while by braking hard a few times (almost to ABS land), but it always comes back. There are no codes and the brakes have plenty of pad left front and rear. Stops strong all of the time. Is this brake checking? I've heard the term but never run into it so I guess I don't really understand what is happening and how to get rid of it. I am completely comfortable disassembling the wheel/brake/rotor/calipers to do whatever is necessary, just haven't ever had this happen before. I have had warped rotors on other cars and this just doesn't feel the same, no strange pedal feedback at all and sometimes after I brake hard, it will go smooth for awhile. What do you guys think? | ||||||||||||||||||||

most likey pad material is building up on the rotors this is fairly common , alot more common than warping the rotors google stoptech, they have a write up about it I believe | ||||||||||||||||||||

Thank you for that reference. I've used a random orbital sander with garnet wood-specific sandpaper for decades to clean up rotors.
