100 percent wrong. Brembo is the only aftermarket that says this everyone else disagrees, but there highend race brakes are mostly slotted now. All of us with race/track C63's have slotted brakes because the stock AMG rotors don't last very long on the track. I had an AMG with cross drilled brakes, their not as good as my slotted. My track cars have slotted brakes. No track guy uses cross drilled disks. Go to the C63 forums and the rest of the AMG forums to find the truth. Or you can look at these links here.
So you're telling me that the transmission is not designed to go into neutral? LOL
Yes. they r not designed to go into neutral when u driving.
And you are crazy man. people buy a Mercedes is to enjoy driving. I am not gonna drive my car everytime i have to worry my break gets overheat. I cant see anyone will do ur recommendations, let go the break when stop for more than few secs lol. That is the most retarded solution i ever heard for plp to avoid wrapping rotors.

I didn't say you did it while you driving you knob, you do it when you're at a stop. Jesus christ. Yeah, you don't do it while your driving down the road. Common sense.
As i know; "Brembo/Textar/Jurid/Zimmermann", these are the only companies that makes Rotors/pads for (X204) as OEM,,
i don't think MB will trust & make contracts with such a companies that not reliable to go with..!??!
-;ZAYED;-
Mercedes-Benz doesn't have contracts with manufactures to make aftermarket disc's, companies purchase CAD drawings and such from either third-party companies or from the factory then they make the parts. There's no contract with Mercedes-Benz to make parts for them. Unless it's standard equipment. But yes those companies are good.

So u telling me i have to do that every time i stop. Jesus christ, i better go take the bus rather than doing that BS. Maybe I am wrong, i honestly cant see plp do that except for the mentally retarded plp.

Jesus, you didn’t read a single thing I wrote.
All I did was tell you guys what was causing the issue. Pay attention.
if you have a 4500lb SUV with 300hp and you are driving hard enough to heat up the rotors to a point where the metal matrix can reform under pressure. When driving it hard and the brakes are hot, when you come to a stop, don’t load up the brakes. That is what is warping the rotors. It’s at a prolonged stop with your foot is on the brakes. Since these are not 2 piece brakes, the disk cannot center itself to the caliper. This means after being stopped at a light for more than around 10 seconds after hard driving will bend the rotor. It’s not just the heat, it’s heat and the pressure of the pad being placed on the rotor in one spot at a stop for a time and as it cools, it will warp right we’re the pad is. Which is why I put it in neutral at a light if the disks are hot. I don’t drive and put it in neutral while moving. By doing this will prevent warping of the rotors no matter how hard you drive.

You refers to aftermarket, who meets or Exceeded the MB spec. parts,
it's another things..!?!,
are you saying all mechanical/Electrical parts are made by MB..?,
MB never/ever make their own parts for their cars or even trucks..!
genuine parts of main MB factories "ZF GMBH" & "(TSLA-AG)" means the parts are proven to be an official MB, as a lifetime or limit contracts with many companies ..!

Understand your point very well, Thanks for that..
as general, Engineers choose the proper brake system, upon to:-
A) Estimate brake system energy capacity vs mass of vehicle weight.
B) Approximate brake system gain requirements, with Calculate vehicle deceleration.
C) Establish brake proportioning for ideal balance.
D) Determine pedal ratios, booster output, and hydraulic system gain.
E) Differences between brake fluid chemistries.
F) Specify brake caliper components.
G) Differentiate between brake pad friction material.
H) Select the proper Rotor spec. for application-specific needs.

Your point is?
If it's to say that Mercedes or any other car maker tried to build a brake that won't fail due to those determinations you have described, then why do they are other cars have issues with this at times? Like airflow, weight, aggressive driving and cooling. None of which you explained. But that's ok, because sometimes, just sometimes other factors comes into play that's bigger than everything you and I listed. It's called "COST".
Because there have been people here having the same issue, I would attribute this as a cost item where MB should have ignored, but that is never possible when the engineers don't make the final decisions.
Holes are for looks. At the track they cause premature cracking and get filled up with brake dust. That's a fact.
Brembo brakes that come on the cars from factory are designed for street, mostly to look cool. They get destroyed quickly at the track once pushed hard.
Can't say all drilled Rotors should fail in track in general, No one really uses them for track purpose. They are an inferior product for the track.
depend what's they designed for..!,,
street use drilled Rotors are soooooo differ than track purpose..?!?!? Yes, mostly for wet applications and they look cool. They offer no performance advantages VS slotted rotors. Carbon rotors are a different animal all together with different make-up and different pressures on the disk.
I haven't really said anything to this derailed thread, but I think its about time.
Unless you can show everyone your credentials on friction science, mechanical engineering, or physics; everyone should just believe in what they believe. Fact is that braking technology has come a long ways, Certainly Brembo, Akebono, Stoptech, etc has a ton of scientific data about their brakes calipers, rotors, and pads and why each one is intended for a certain application.
Nobody has actually tracked their GLK, and even if you did the transmission or engine would overheat just as quickly as the brake system.
Our front ones replaced, again. First time they were replaced at around ( or below ) 20k mark. Under warranty.
Rears done too, maybe 10k after that. The same reason, warped. Vibrating under braking from highway speeds.
A while ago started to feel the same vibration, again. We are around 50 k now.
And surely not driving agressively ! More the opposite.
Took it to a regular service, and yes, fronts a bit warped.
But this time I didn’t allow them to put MB stuff down there.
Ordered Brembo discs and brembo pads myself (09.9825.21 and P 50 086) , and got them installed last week at an indie shop.
Should be OK now !
Sadly, sold the GLK yesterday, so cannot comment how the Brembos last.
