BUT I AM very happy with my 47i6 upgrade brakes Andy as my recent feedback to Audi UK (Kelly Hathaway said:
"Some feedback Kelly, my brakes are superb, thank youâ¦
Stafford Audi did my 47i6 upgrade in September 2013. As agreed with Stafford Audi, and as discussed with yourself, I bedded-in my brakes fully and according to the Brembo recommendations.
The initial 'bite' and 'pedal-feel' improved dramatically over that first 30-miles or so (of bedding-in), but did take some 100-miles to feel entirely satisfactory. However, with 1000-miles use the brakes are now quite superb, better than original, and with very low dust.
For your information I am running WITHOUT the 4 x REQILL® Tuned Absorbers, (I removed them on day-1 as I told Martin Sander I would), but will fit those if and when brake squeal reoccurs, however, I do not expect them to be effective."
That said, I do expect at some time to see exactly the same problem Sean has; if and when brake squeal occurs I will fit those 4 x REQILL® Tuned Absorbers if only to evaluate for myself; no point in evaluating these items unless brake-squeal IS an issue.
I am aware that the 47i6 upgrade is designed to address a number of issues and not only brake-squeal which is what those Brembo replacement pad are intended to do (and I do have a set of those to try maybe (?), as I have sets of Mintex self-adhesive anti-squeal shims in stock too), however, for the time being I've zero complaint.
But as you've done Andy I bedded-in my brake pads fully to the Brembo recommendation and I do think that initial bedding-in process conditioned the friction material properly.
Note: I did provide Audi UK with a copy of the Brembo procedure, have supplied the same to two Audi dealers, but at this time know of no dealer that's undertaking this procedure, or advising customers, to do the sameâ¦
