Intended Use and Vehicle Placement

The presented brake disc is designed for operation on the front axle, with the possibility of mounting on both the left and right sides. This solution simplifies part selection during brake system servicing, allowing for symmetrical replacement of components on both sides of the vehicle without the need to distinguish between dedicated versions.

Vehicle placement includes:

• front axle – the main area responsible for the majority of braking force,
• left side – cooperating with the left caliper and hub,
• right side – cooperating with the right caliper and hub.

This allows the disc to be used as a replacement part on both sides, simplifying service logistics and reducing the risk of selection errors.

Technical and Functional Characteristics

The original Mercedes brake disc has been manufactured according to the factory specifications of the producer, meaning the correct geometry, working thickness, and thermal parameters are maintained. The construction is adapted for cooperation with standard brake pads, ensuring:

• stable friction across the full range of operating temperatures,
• even wear of the working surface,
• proper cooperation with ABS/ESP systems.

As a component from the Brake Discs category, the product is responsible for transferring braking force from the caliper to the wheel, and its proper fitment is crucial for the effectiveness and repeatability of the braking process.

Original Origin and Condition

The disc comes from the Mercedes brand offering, which means compliance with factory quality and construction standards. This is a used part, making it a sensible choice for users seeking original components at a more attractive budget than for new items. A used OEM part maintains proper fitment to the hub, caliper, and brake system shields, reducing the risk of installation issues.

Application in Service and Brake System Modernization

The presented brake disc is suitable for both standard operational replacement and comprehensive front axle servicing. It can be used as a substitute for the factory-installed disc in vehicles matching the model designation, provided appropriate installation procedures and checks of cooperating components (pads, calipers, lines, hubs) are followed.

If you are planning a comprehensive repair or modernization of the braking zone in your Mercedes and need other components from the same group, such as additional discs, compatible pads, or supplementary lines, check the available parts in the Mercedes Brake Discs category.

Technical Support and Selection of Used Parts

When working with the brake system, conscious selection of used components is particularly important. To better understand how to safely use salvaged parts within the braking system, including elements cooperating with discs, it is worth consulting specialized materials.
