Options for Replacing Brake Discs on the 2019 C205 (Facelift) C63S?

[Preedom]

According to the headline, my 2019 facelift C205 C63S need replacement front discs. The automobile has barely accumulated a few thousand miles since their replacement, and although they are not worn, one of them is significantly deformed. The vehicle has been utilised infrequently, having accumulated 14,000 miles from its inception and merely 3,000 miles since the installation of new Mercedes discs and pads; so, I am quite disheartened that one of them has warped after such minimal usage. Considering the expense of the discs from MB and the rapidity of this failure, I am dissatisfied with the prospect of incurring the AMG tax again, hence I am exploring alternative options.

Regrettably, the C63S is equipped with distinct brakes compared to the C63, and I am encountering difficulties in locating aftermarket alternatives. Despite being Brembo brakes, I anticipated they would be readily available; yet, the reality is quite the contrary. Has anyone here successfully procured replacement front discs and pads for a C63S? Thank you!

I regret to learn that. Are you aware if one or both discs are distorted?

I would refrain from replacing them without first verifying the callipers. If the callipers become stuck, the head may accumulate pressure, resulting in the warping of the disc.


I am uncertain about your precise model; nevertheless, in certain instances, AMG cars equipped with enhanced composite discs may also utilise conventional discs.

I cannot ascertain if yours is included, but another member or a brief search may provide confirmation. Best of luck organising it.

It is essential to have the callipers inspected. Authentic Mercedes-Benz components come with a two-year warranty; however, demonstrating that the issue originates from the disc or calliper may prove challenging.

[Preedom]

Greetings, everyone. I appreciate your responses. The callipers were inspected a few months ago when they were detached, and the pads were examined. No problems detected. I will conduct an additional inspection and cleaning when I organise the discs.

The C63S is equipped with distinct discs and pads compared to the C63; nevertheless, they are not composite but rather steel. Composite brakes were an optional expense I chose to forgo. I am currently seeking recommendations for discs and pads. Any suggestions would be appreciated. They are exceedingly difficult to locate outside of Manitoba.

[Lemmand]

Do they appear as such? These are composite brake discs, consisting of a steel friction surface and an aluminium bell.

Some individuals presume that composite refers to carbon ceramic, which I guess is what you imply by cost choice.

Since you are located in the Midlands, contact MSL Performance; they typically offer competitive prices for authentic discs and provide installation services as well.

[Lemmand]

Excellent location.

Several years ago, rear disc brakes were unavailable at my primary dealership, so MSL installed a set of Brembo brakes instead.

Certain primary dealers may provide attractive prices on brake discs and pads; therefore, it is advisable to compare options.

Has the disc's warping been verified using a dial gauge?
Are you experiencing a vibration in the steering wheel while braking? Instead of through your seat for the rear brakes.
Exercise caution when diagnosing the issue, as warped discs may produce comparable braking vibrations caused by worn front control arms. I experienced same issue with the CLK, having replaced the MB disc and pads, but ultimately, it was determined to be the front control arms.

As you mentioned, the fees associated with your discs can be prohibitively high if mistakes are made.

[Preedom]

They are not distinct two-piece brakes, as you envisioned (I possess those on my Ultima); nonetheless, in relation to your inquiry, upon closer inspection, the bell may be composed of aluminium. It is a singular assembly that cannot be disassembled, lacking any fasteners. I saw the original query as enquiring whether I possessed the optional carbon composite brakes, as that is the common assumption when the term "composite" is spoken.

I am unable to locate any part numbers for the discs or pads, and it has been proposed that this is due to Mercedes' intention to restrict the aftermarket from providing certain AMG components. Certainly, this implies they can impose charges over £1,000, which is absurd. Any part number for these discs and pads would be beneficial. Thank you!

There exists a composite variant featuring an aluminium bell and a steel disc, which is cast as a single unit rather than in two separate components. I recall they were featured on the 507 and Black Series.

Have you received a quotation from a primary dealer yet?

Significant issues with disc thickness variation and judder may arise if the vehicle is stationary with damp brakes, frequently following cleaning. Moist pads leave an indelible mark on the disc that cannot be eradicated. Merely a consideration to raise awareness.

£1,400, no thank you! I believe I have cross-referenced and identified a Brembo disc and pad set that is compatible, shared with the AMG GT and E63S, at about half the price of Mercedes-Benz.
