    Panic Stop

    So I was driving home and the idiot in front of me decided he needed to turn with no blinker or notice. I braked as hard as I could and stopped about 1/2" from his bumper. Since then, I have had better brakes! I have a firmer pedal and better stopping power.

    What could have happened?

    you ground a layer of road crud off the pads -

    and burned a layer of debris off the rotors -

    no - really - I'm NOT kidding -

    OK, you gotta splain dis. How do you get "road crud" and "debris" on a spinning rotor that gets frequent brake applications?

    ------------------------------
    one of the common complaints is pulsating brakes -

    some wrongfully believe it is caused by warped rotors -

    but after the rotors were cut - the pulsating went away -

    the true problem was a build up of "stuff" on the rotors -
    and a few really hard stops will "eliminate" this "stuff" -
    just as effectively as cutting the rotors -

    "granny" driving - and being "easy" on brakes won't "burn" the bad stuff off -
    you got to get them really hot -
    ------------

    and before anyone jumps in -
    NO - I am not saying you need to burn up your brakes every time you stop -
    or once a day - or once a week - or once a month -

    just like you don't need to do a WOT every time you accelerate -

    slipgate simply said his brakes feel tighter after a hard stop -
    and this is a possible explanation why -

    Re: Panic Stop

    OK, I agree with that except that what is on the rotors and is being cleaned off by hard stops is brake pad deposits, not "road crud" or "debris".

    This is what you are talking about.

    The rotors and pads are only about 3 years old (all 4). No pulsating or anything like that before or after. I just have a stiffer pedal now after the panic stop like something seated or perhaps some air in the line got moved along .

    Re: Panic Stop

    Any sign of a dragging caliper? Might be worth checking.
