My understanding is that pads will transfer some material to the rotors and you want this to be done as evenly as possible. Try this: (find a safe place to do it, of course) Make ~ 6 to 10 hard brake applications from ~ 60mph to ~ 20 mph (not fully stopping) with a few minutes of driving between each brake application to allow the brakes to cool. Avoid making a hard brake application then coming to a complete stop. </div><div class="gmail_default" style="font-size:large"><br></div><div class="gmail_default" style="font-size:large">EjR </div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Sat, Sep 27, 2025 at 10:56 AM john niolon <<a href="mailto:jniolon@att.net" target="_blank">jniolon@att.net</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
