Purpose and Compatibility
The presented set of drilled brake discs has been designed for the front axle of Mercedes vehicles from the W204, C207, and W212 series. The components are prepared for installation on both the left and right sides, allowing for the correct direction of drilling and even distribution of braking loads.
By using the manufacturer’s original solution, the discs are compatible with the factory braking system of these models, ensuring a proper fit with calipers, hubs, and heat shields.
Construction of Drilled Brake Discs
The drilled working surface of the discs promotes efficient dissipation of heat and friction material wear products. The holes in the working surface limit overheating, helping to maintain a stable friction coefficient over a wider range of operating temperatures.
This design solution:
- improves resistance to brake fade during intensive use,
- facilitates water drainage from the working surface in rainy conditions,
- promotes even wear of brake pads.
Vehicle Placement and Installation Aspects
The set is intended for installation on the front of the vehicle, on both the left and right sides. Correct alignment with the direction of travel is crucial for maintaining the function of the drillings and the even distribution of braking forces.
During installation, it is recommended to:
- thoroughly clean the hub surface before mounting the disc,
- check for radial and axial runout after installation,
- use new mounting bolts according to the vehicle manufacturer’s recommendations.
Performance Characteristics and Application
Original brake discs with drillings perform well in cars used in both city traffic and on highways, where the braking system operates under varied load conditions. The disc design supports braking force stability, which is important at higher speeds and during frequent emergency braking.
Components of this class are particularly recommended for drivers expecting predictable brake system response and performance characteristics consistent with the vehicle manufacturer’s original specifications.
Condition and Origin
The offered set of brake discs consists of original used Mercedes parts. These components are sourced from dismantled vehicles and offer a solution for users seeking factory original braking system parts at a more favorable price than new replacements, while maintaining the original manufacturer’s design.
Braking System Expansion and Technical Knowledge
If you are planning a comprehensive repair or upgrade of the braking zone in your Mercedes and require other parts from the same group, such as additional discs, pads, or brake lines, check the available parts in the Mercedes Brake Discs category.
When working on the braking system, it is also worth paying attention to the condition of the calipers.
