Are these covered? I think my rotors are bad. vibration when applied at high speeds. The pads look to be about 50%. Also I notice the front backing plate seem to have rust spots...I was going to remove and power coat but that too she be covered under wrnty.

PeterUbers

they may cover it under warranty but with 27k miles I doubt it

gaspam

wear and tear items like pads, rotors, plugs, etc arent covered unless it premature failure due to manufacture defect/recall

I just finished a road trip from my home here in Montana to northern Minnesota, then to West Chicago (AMS), and back to Montana. I am at just over 11k and I too have begun to experience a definite vibration when braking at high speeds. A 2016 with 11k of mostly highway miles and an occasionally severe vibration when braking at high speeds is unacceptable. I will insist on warranty coverage.

a friend GL63 same issue at 8k. He is aware of what went wrong in his case.
Very hot day of driving and then drove into water.
My car is a weekend driver not track just normal street...

Yes, never expose hot rotors to water unless you want warped rotors.

8k 11k 27k rotors warp...I don't think this is normal.
My M5 58K 3 sets of pads and was perfect.
I am still on my first set of pads..

My plate is full of rust spots. Took my wheels off to clean everything and notice lots of rust on the backing plates.
Are they coated, I guess it is not aluminum since they both rusted.
Wonder if that part is covered....

I've stated on other threads that I have never had good luck with Benz rotors when used even semi-aggressively. I had two sets replaced under warranty on my 2014 E550 and I'm now experiencing the same thing with my E63. Brembo manufactures the brakes for MB. The calipers are their GT calipers, but the rotors are not the full floaters that come with the GT package either front or rear. I cannot understand why MB would bother with these substandard rotors on a $110k 4600 lb car with nearly 600 HP stock at the wheels. I really want to upgrade to better brakes, but I may start by having MB warranty these rotors and pads, and then install Girodisc full floaters front and rear before springing for a completely new set of rotors, pads, and calipers. MB should have to pay a price for this inconvenience, thus I will warranty first.

Dealer can clean and lubricate brake system.

Hoping for new rotors/pads and backing plate....
I am willing to pay for the pads.. Hell they have about 50% at 27K when check with my friends 2016 4k ML63.
I just have a feeling they will say it is not covered and that is that...she me the $$$ and we will install new rotors..

otakki

Those are not brake dust, is it? I thought rust would have a brownish tinge to it.

vdubpower

I don't think that is rust. Mine have the same. The backing plate wouldn't have affect on drive though would it.

Just has my front and rear pads changed at 42000 miles. They said rotors were OK .

2012 CCB E63

They do have the carbon ceramic brake option, which is downright awesome. I have tracked my car quite a few times, and at no time have the rotors warped or the brakes given out.
Something to think about if you're going to upgrade

BerndV

I considered them when I purchased the car. However, I had heard and was told by the salesman that they can be somewhat noisy in daily driver use and that they did not perform as well in that application. I have had no personal experience with carbon ceramics, perhaps you could provide a detailed write-up or a link to one that would give me more insight into how they perform in daily use i.e. noise issues, cold braking, wet braking when cold, etc. However, many other manufacturers produce high performance street cars with conventional steel rotors and they never have the issues that I've had with MB rotors. They simply ignored their motto "Das beste oder nichts" when it came to steel rotors for these cars. They should have opted for the Brembo full floaters.

gaspam

definitely not normal... my rotors have 62K miles on them and still good... when they finally do wear out i will go with girodisc as will save about 36lbs of rotational mass and when they wear out can just replace the disc while keeping the rotor hat, which will save $$ going forward

2012 CCB E63

I can write up a thread, but it would be quite boring. Brakes work great 100% of the time, no issues in rain/cold, daily driving, etc.

Just thinking you could buy the parts and convert your car to CCB if you wanted to, instead of sticking with steel rotors.

BerndV

Perhaps this may be the ultimate, albeit expensive, solution. I may try the Girodiscs with new stock pads first as a low cost alternative and see how well they perform. If this does not solve the problem, then I will consider the carbon ceramic conversion.

From what I have heard, those plates are designed to shield heat in cars with AWD system.

jylee

I don't think they are covered. These parts are not expensive and easy to replace. For less than $300 (rotors and pads) at Rockauto, and a two hours of work. I wouldn't be bother to require for warranty coverage.

kponti

Full floaters tend to make noises as well as they age. Clicking noises when the brakes are initially applied

pghc63

interesting thread
2 months ago i picked a GLA 45 and noticed vibrations at high speed braking after 1k miles , dealer said that rotors had corrosion marks on them and replaced under warranty , no questions asked
my e63 have 6 k miles and so far no issues

BerndV

That has not been my experience. I've had several non-MB cars with full floaters including a 911 that I tracked. I never had any warping, vibration or noise. I think MB went with the relatively inferior Brembo steel rotors because of the carbon fiber option available on these cars. I'm going to install Girodiscs for now but eventually I will install the factory carbon fiber rotors, pads, and calipers. When I purchased the car, none of the dealers in SoCal had the exact color and options I wanted that also included the carbon fiber brakes. It's a straightforward bolt on swap but will cost just under $13k.

2012 CCB E63

One thing to note, and it might not apply to you, but you can't run 18" wheels with the CCB rotors. Not sure if you have winter tires/etc.

You'll love the CCBs
