Intended Use and Vehicle Placement

The disc is designed for rear axle operation, with the possibility of mounting on the right or left side. This solution simplifies component selection during rear axle servicing and allows for consistent restoration of the braking system geometry in compact Mercedes models.

Placement on the vehicle covers the rear axle, which is crucial for braking stability, especially during dynamic maneuvers and when operating with assistance systems such as ABS or ESP.

Technical and Functional Characteristics

As an OEM component, the disc works with factory-specified calipers and brake pads for the given Mercedes generation. The appropriately selected working diameter, thickness, and friction surface enable even distribution of braking forces between the front and rear of the vehicle, contributing to stable handling and predictable response to brake pedal application.

A used brake disc is a good solution when an economical repair while maintaining compliance with factory specifications is a priority. This allows for reduced service costs while maintaining compatibility with original braking system hardware.

Benefits of Using an Original Rear Disc

Using an original rear brake disc in a Mercedes W169 or W245 helps maintain the consistent operating parameters of the entire system. Proper balancing and fit to the hub minimize the risk of brake pedal vibrations and unwanted braking noises.

For the user, this means:

• more stable braking across the full speed range,
• proper cooperation with safety systems,
• easier diagnostics and servicing due to maintaining factory configuration.

Selection and Safety When Purchasing a Used Disc

When choosing a used brake disc, it is crucial to pay attention to compatibility with the specific vehicle model and the condition of the working surface. A correctly selected component from this group allows for trouble-free installation and reduces the risk of additional work on the braking system.
