<div dir="ltr">Glen, great point!<div><br></div><div>Seems that many race pad manufacturers try to give us the most material for our money with a big, rectangular friction material puck. This definitely works against us with the ancient, two piston calipers we run. More heat, and more surface speed out towards the edge of the rotor is a recipe for radial taper.</div><div><br></div><div>I've found with enough complaining, I can get them to change the shape of the pad to a trapezoid, and it really does help as you say. It doesn't eliminate taper on my GT6 that's brutal on brakes, but it is a big step in the right direction.</div><div><br></div><div>In lieu of a properly designed friction puck, I sometimes use a big file to adjust the shape of the friction material to accomplish the same thing.</div><div><br></div><div>Running a thick spacer behind the pad as they wear down also helps keep the pistons true to the bore, and reduces heat transfer to the fluid/seals.</div><div><br></div><div><br></div><div><div><div dir="ltr" class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div dir="ltr"><div dir="ltr"><div>Jason Sukey</div><div><span></span><span></span>JS Performance Motoring, LLC<br></div><div>440.984.7720</div><div><a href="mailto:jason@jsperformancemotoring.com" target="_blank">jason@jsperformancemotoring.com</a><br></div><div><a href="https://www.facebook.com/JSPerformanceMotoring/" target="_blank">https://www.facebook.com/JSPerformanceMotoring/</a><br></div></div></div></div></div></div></div></div></div></div><br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Wed, Jul 3, 2024 at 12:14 PM fubog1 via Fot <<a href="mailto:fot@autox.team.net">fot@autox.team.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"><div><div style="font-family:Arial,Helvetica,sans-serif;font-size:16px"><div></div>
<div dir="ltr">Another point to consider re pad selection, & I don't see mentioned, is make sure that the pads have the correct taper ie backer flat down, the profile of the pad side should taper down towards the center of the disc/bottom of the pad to some degree, a trapezoid with the long side up, ie not be rectangular shape.</div><div dir="ltr">Reason is that a lot more heat is generated towards the OD of the disc, & they'll wear more; having less friction surface towards the bottom of the pad w/a taper evens the pad wear, & it won't develop the other form of "taper", that usually requires that 1st brake pedal stab as the rectangular shaped pads do as they wear.<br></div><div dir="ltr">This applies to all TRs.</div><div dir="ltr">I've also seen many cases where "interchanges" don't consider the shape of the pad, although the pads are dimensionally correct & fit.</div><div dir="ltr"><br></div><div dir="ltr">Glen Efinger<br></div><div><br></div>
