Purpose and Brake System Fitment

The presented brake disc is dedicated for installation on the rear left side of the vehicle, which is important for the correct distribution of braking forces and cooperation with the brake caliper and pads. Its original Mercedes origin promotes the maintenance of appropriate geometry, working diameter, and working thickness, which translates to stable system operation under typical usage conditions.

Thanks to the use of a factory design, the disc works with the standard ABS system and driving stability systems, minimizing the risk of vibrations, uneven braking, or accelerated pad wear. This solution is particularly beneficial when servicing the rear axle, especially when you want to maintain braking characteristics close to factory settings.

Technical and Functional Characteristics

As an OEM part from the Brake Discs category, the product has been designed for precise fitting with the wheel hub and brake caliper in Mercedes W169 and W245 models. The appropriately selected working material of the disc promotes stable heat dissipation during braking, which reduces the risk of overheating and deformation of the working surface.

Its placement on the rear left side of the vehicle allows for the maintenance of proper symmetry in the operation of the entire axle, provided a compatible disc is used on the opposite side. In practice, this means predictable vehicle response to brake pedal application, which is important both in everyday city driving and during longer journeys.

Condition, Origin, and Benefits of Choosing a Used Part

The offered brake disc is a used part, which allows for reduced service costs while maintaining the original manufacturer's specifications. Choosing such a solution is particularly beneficial for vehicles used daily, where a reasonable balance between quality and repair budget is important.

A used OEM part from disassembly also provides real support for the circular economy – the reuse of functional components reduces waste and raw material consumption.

Safe Selection of a Used Brake Disc

When choosing a used brake disc for a Mercedes, it is crucial to verify its compatibility with the OEM number and interchangeable part numbers, as well as its fitment for the specific body version and braking system. Proper selection helps avoid problems with installation, uneven pad wear, or incorrect operation of ABS and ESP systems.
