The technicians and service manager all said that this was "a common problem with Stingers with the Brembo brakes" and that I was not the first guy to bring my car in for this issue.
Isn't it interesting, that not one Base, Premium or GT-Line (i.e. not Brembo) has complained of this? Does anyone remember a forum member complaining about "factory brakes"? I don't.
Nothing about this "Brembo" issue is commonly known or noticed by the vast majority of GT Stinger owners, or else this forum would be flooded with traffic, all coming here to carp about it. The flow of complaints is a steady trickle. I read all of these threads and refer back to them a lot. That's because this issue crops up at any time/mileage: I am not immune, just not one of yous guys (hopefully not "not yet"

). It is a common problem, just not a majority or even large minority one. If it were, Kia would have put out a TSB long ago and called in all Brembo brakes and replaced the pads with Euro spec or something from a short list of approved
aftermarket pads: and Kia would have ceased long ago from putting in the "US spec" pads. Here we get the ear full. Out in the wider Stinger world, drivers are happy with their brakes, or they take them in to get serviced and are then happy. Or they finally get tired of dealing with Kia and ditch the car.
Yes, the "Speed Week" Stinger had fading brakes on day one; Kia sent over a set of Euro spec pads (night expressed them, if I recall correctly), and all subsequent use of the car was fine. I've always wondered if Randy Pobst was lapping with the Euro spec pads or OEM US spec: he did not complain or observe any brake fade issues. I think the car Pobst used was totally stock: I do know that other drivers of the car did complain about the brakes losing performance after the first lap or two: but he did not: leading me to my conclusion that it is the driver: he's just that much better at using brakes than the other complaining drivers. What this has to do with shuddering brakes is debatable.
I've said this before: the US spec Brembo brakes are not ready for a track day. I take this as gospel from those who know and why would I argue from a position of no experience? If I ever do a track day, it will only be after I've replaced the pads with suitable
aftermarket performance pads, and probably even rotors. I will also get stainless brake lines and replace the fluid with higher spec to take the heat, etc. Anything else? I've already got all that on my short list of
mods, if I ever do track my Stinger.
