Purpose and compatibility with the Mercedes W204

The presented set is dedicated to the front axle of the Mercedes C-Class W204 generation in versions equipped with the AMG package. The set includes a disc for the left side and a disc for the right side, which facilitates maintaining full symmetry of the braking system's operation. Thanks to this solution, the driver receives a consistent set that can be installed in place of the factory components without the need to modify the structure of the calipers or hubs.

The original origin from the Mercedes AMG range means maintaining factory performance parameters, such as friction characteristics, thermal stability, and compatibility with the stock brake pads intended for this version of the system.

Technical characteristics of the brake disc set

The set includes two discs intended for installation on the front of the vehicle, on the left and right sides. This layout allows for even distribution of braking forces and proper cooperation with assistance systems such as ABS or ESP. The design of the discs has been engineered for more intensive use, typical of AMG versions, with an emphasis on thermal stability and resistance to overheating.

In practice, this means:

• consistent performance characteristics on both sides of the front axle,
• maintaining predictable braking efficiency under higher loads,
• proper cooperation with Mercedes' factory sensors and safety systems.

Benefits of using original AMG discs

Choosing the original AMG brake disc set for the Mercedes W204 primarily ensures perfect fitment and the preservation of factory braking characteristics. Unlike aftermarket replacements, components from this series are designed with a specific model and trim level in mind, which minimizes the risk of installation issues and unwanted vibrations during braking.

Key advantages include:

• preservation of original geometry and rotating mass,
• consistency with the factory AMG package, including compatibility with calipers and pads,
• stable, repeatable braking across a wide range of operating temperatures.

Condition of the item and practical application

This is a used brake disc set, sourced from disassembly, intended for informed users seeking original components at a reasonable price. This type of solution works particularly well for maintenance repairs where the priority is to maintain the factory specification of the braking system without resorting to cheaper, unreliable replacements.

Before installation, standard workshop verification is recommended, including inspection of the working surfaces, thickness measurement, and assessment of any potential runout to ensure proper operation in a specific vehicle. When combined with appropriately selected brake pads, the set will allow for achieving the predictable, comfortable braking characteristics typical of the AMG version.
