    A few months back I posted an issue with the brakes on 02 Sonata. Ca
    had 75,000 miles on it and dealer had turned rotors twice and replace
    them once. The rough braking had returned and Hyundai decided the
    were not going to honor their warranty. A bad decision on thei
    part

    I bought expensive racing rotors and pads for around $275 which worke
    well for a few thousand miles and then the problem returned. I als
    purchased a runout guage and checked the new rotors and the hubs an
    the max runout measured was .0015 inches, well within the spec o
    .004

    After the problem returned, I measured the runout and it was stil
    within tolarance

    I then had the original Hyundai rotors turned and they measured .005
    inches of runout, out of spec according to the manual. However, th
    problem is now gone but do not know for how long

    Someone sent me a link to an article that claimed the problem wa
    depositis on the drum which changed the friction around the drum.
    Also, someone wrote that he had fixed this problem by a series of 1
    hard stops

    I am beginning to believe you guys. Was not able to fix the proble
    by 10 hard stops or by sanding the rotors by hand but turning th
    rotors fixed it. I told the machinest to remove the minimum materia
    when turning the rotors

    Anybody have any ideas

    And, by the way, have never burned out a light bulb in this car in
    years
