Ok, as most guys will know that I first experienced intense brake-squeal on my car in February 2012 and deciding not to wait for Audi to sort the problem set about developing my own resolution that has been 100% successful since applying the Mintex self-adhesive anti-squeal shims.
However, throughout 2013 we've seen the 47i6 brake upgrade released and applied to cars where owner/drivers have registered a complaint (a number of complaints are valid); anyway, having seen/inspected/viewed/driven a fair number of 'early' 47i6 brake upgrades, and being totally under whelmed by the experiences, I decided waited for the storm to subside before having AUDI apply the upgrade to my car.
Inspiration for me to make the change came from Martin Sander himself; I challenged Martin directly at the Goodwood Festival of Speed, we discussed the issue at length and followed with correspondence passing back and forth. Finally Martin gave me good reason to have the 47i6 upgrade applied and I have now done so, however, I did ensure that I had alternatives in hand just in case, and those alternatives have been detailed elsewhere.
So last week the change was made. I specifically requested that the Master Technician did not road test of the car unless he was prepared to undertake (to the letter) the recommended Brembo brake bedding-in procedure; happily for me Stafford Audi agreed (that said I have nothing but praise for ALL of the guys at Stafford Audi).
Second service and brake upgrade completed I drove away from Stafford Audi and onto fast but lightly loaded roads applying the bedding in process as safely as conditions allowed. It took less than 20-miles to be fair, and the changes/improvements from start to finish were dramatic; the brakes are as good now as they were on the original set-up but are now: a) much quieter in application, and 2) amazingly dust free. Ok, the pedal remains slightly 'soft' to the feel but it is improving, as is the initial 'bite'.
Interestingly, the temperature build-up/bite of the pad in application can seriously be felt, neat!
Conclusion: I like 'em!
Oh! And I was emphatic with Martin Sander and others within Audi UK (and elsewhere) that I was not going to drive around with those 4-vibration-damping bobbins on my calipers , so they are OFF! The only purpose for these items (in my view) is to mask any resulting noise/squeal and I want to hear at first-hand any noise/squeal that may develop, as I'll then apply the same resolution as before (Mintex self-adhesive anti-squeal shims).
