Intended Use and Brake System Fitment

The presented brake disc belongs to the Brake Discs category and is intended for installation on the rear right side of Mercedes W169 and W245 series vehicles. Its placement on the vehicle is factory-defined, which simplifies the selection of the correct component during the service of a specific wheel and minimizes the risk of ordering errors.

Thanks to its design, which is compliant with the manufacturer's solutions, the disc is compatible with the stock hydraulic system, sensors, and standard brake pads designated for this axle. Maintaining the original geometry and operating parameters translates to stable deceleration, even pad wear, and predictable vehicle behavior during braking in typical road conditions.

Technical and Functional Characteristics

The brake disc is designed as a component for the rear axle, where vehicle stabilization and support for the front axle's braking system are prioritized. Its placement on the right side allows for proper distribution of braking forces and correct interaction with the vehicle's safety systems.

Choosing a used, original component from this group is beneficial wherever it is important to:

• maintain factory braking characteristics without altering the manufacturer's design,
• ensure compatibility with stock calipers and pads,
• reduce service costs while using parts from the original production line.

A component configured in this way allows for brake system servicing consistent with Mercedes' design principles, which is particularly important for vehicles used intensively in urban traffic.

Condition, Origin, and Service Application

The offered brake disc is a used component, allowing for economical brake system repair while maintaining the original origin of the part. This type of solution is often chosen for fleet vehicles and cars used long-term, where a sensible balance between cost and compliance with factory specifications is crucial.

Before installation, standard service procedures are recommended: verification of the working surface, check for radial runout, and assessment of compatibility with currently used pads. A correctly selected and installed disc on the rear right axle supports vehicle stability during braking, reduces vibrations, and helps maintain even wear of friction components.

Integration with Other Brake System Components

Replacing a single disc on the rear right axle often necessitates an inspection of other brake system components. In service practice, it is advisable to consider a parallel check of the left-side disc, the condition of the pads, flexible hoses, and caliper operation to maintain consistent braking parameters across the entire axle.

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

Technical Support and Selection of Used Components

When selecting used brake system components, it is advisable to follow a proven procedure for assessing their technical condition, service history, and compatibility with the specific vehicle version. A detailed list of inspection steps and practical tips can be found in the article Used Brake System: How to Safely Select Discs, Calipers, and ABS?, which discusses key aspects of purchasing parts from the secondary market.
