In most cases in the past few years, I’ve had to egg out the holes for the 1/4” pins with a drill. <div class="">Mine typically look like the photo of the new one you have on the right. I think the pads are “shared” with the Datsun 240z and they probably fit fine on that car. </div><div class=""><div><br class=""><div class="">On Mar 7, 2018, at 7:21 PM, Brad Eells via Fot <<a href="mailto:fot@autox.team.net" class="">fot@autox.team.net</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><div dir="ltr" class="">Hello Amici,<div class=""><br class=""></div><div class="">Porterfield brake pads in the R4-1 compound were recommended to me. I dutifully ordered a set for my Spitfire.</div><div class=""><br class=""></div><div class="">I should mention the car has been upgraded to GT6 brake calipers, the venerable Girling 16P. My TR4 and 4A also use the 16P.

The Porterfield pads arrived. I found 2 issues. The pad compound shape was not the same as every pad I have previously purchased or what is shown on Porterfield's website. I also found the retaining pin holes in the puck to be too small. The puck itself is the same general dimension as my original Girling Competition pad and does fit in the caliper but I cannot put the pins through the holes.</div><div class=""><br class=""></div><div class="">I simply assumed they had sent pads for the later GT6, the Girling 16PB or M16PB that use 3/16" retaining pins.</div><div class=""><br class=""></div><div class="">8 Emails with manager, Wendy and 1 phone call with engineer Tim and we still have a disagreement. I was told they had sold that exact pad "for 25 years" for my application and no one had ever had a problem or complained. When I asked why I couldn't simply have what was shown on their website as the pad for the 16P, I was told that was just a general illustration and not correct for any specific application.</div><div class=""><br class=""></div><div class="">They have offered to drill out the retaining pin holes to fit my pins. I am honestly disappointed that I simply can't have what fits out of the box and to have to argue the point back and forth through multiple Emails and a terse phone call.</div><div class=""><br class=""></div><div class="">So, my questions to those of you running a 16P (late TR3 through early TR6 and GT6 1968-72 along with many other British applications) are:</div><div class=""><br class=""></div><div class="">1. Are you using Porterfield pads in your calipers?</div><div class=""><br class=""></div><div class="">2. Have you found them to fit the standard 1/4" retaining pin?</div><div class=""><br class=""></div><div class="">3. If you have found them to not fit the pins, are you drilling them out yourself?</div><div class=""><br class=""></div><div class="">4. Does the difference in pad shape concern you at all (photo attached)?</div><div class=""><br class=""></div><div class="">5. If not Porterfield, then what are you using? Without divulging any speed secrets, of course...</div><div class=""><br class=""></div><div class="">I'm close enough to their facility that I can appear there with my pins, pads and calipers to prove what they disbelieve...it just shouldn't have to come to that with a reputable company from my view...</div><div class=""><br class=""></div><div class="">Your thoughts and experience are appreciated.</div><div class=""><br class=""></div><div class=""><span id="cid:ii_jehrmhvz0_16202fa7f1739011"><ap1142008_03_24_10_51_45.jpg></span><br class=""><br class=""></div><div class=""><span id="cid:ii_jehrn3od1_16202faec8903f6a"><IMG_2858.jpg></span><br class=""><br class=""></div><div class=""><br class=""></div><div class="">Thanks!</div><div class=""><br class=""></div><div class=""><br clear="all" class=""><div class=""><div class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr" class=""><div class=""><div dir="ltr" class=""><div dir="ltr" class=""><div dir="ltr" class=""><div dir="ltr" class=""><div dir="ltr" class=""><div dir="ltr" class=""><div dir="ltr" class=""><div dir="ltr" class=""><div dir="ltr" class=""><div class=""><div style="font-size:12.8px" class=""><b class=""><font class="">Brad Eells</font></b></div><div style="font-size:12.8px" class=""><b class=""><font class="">Chino CA</font></b></div><div style="font-size:12.8px" class=""><b class=""><font class="">#35 DP 1962 Triumph TR4</font></b></div><div style="font-size:12.8px" class=""><b class=""><font class="">#76 FP 1969 Triumph Spitfire Mk3</font></b></div><div style="font-size:12.8px" class=""><b class=""><font class="">1965 Triumph TR4A IRS...for the road!</font></b></div></div><div class=""><br class=""></div></div></div></div></div></div></div></div></div></div></div></div></div></div>
