Purpose and vehicle placement

The presented set includes two discs designed for the rear axle, with the possibility of installation on both the left and right sides. This solution ensures material and structural consistency on both sides, which is important for vehicle stability during braking, especially at higher speeds or under load.

Placement on the rear axle promotes even distribution of braking forces between the front and rear, which translates into predictable car behavior in emergency situations. Using a dedicated set for the rear also reduces the risk of differences in braking efficiency resulting from the use of unmatched components.

Technical characteristics and fitment

The set of discs has been developed as a component of the braking system for Mercedes vehicles, which means compliance with the factory geometry of the hub, caliper, and brake pads intended for this design. As a result, installation proceeds in a predictable manner, without the need to modify other components.

Proper fitment to a specific model is also facilitated by identification via the OEM part number and available interchangeable numbers, which allows for verifying compatibility with a specific body version and braking system. This is particularly important when selecting used components, where dimensional and structural compliance is key.

Condition, origin, and benefits of purchasing a used set

The offered set of brake discs comes from the secondary market and has the status of used. For many users, this is a reasonable compromise between cost and functionality, especially when maintaining the vehicle's original specification is a priority. Used braking system components, selected according to the part number and purpose, can be an effective service solution with a controlled budget.

Choosing a complete set for the rear axle reduces the risk of differences in wear and performance parameters between the left and right sides. Additionally, using an element from the Brake discs group dedicated to a specific model platform makes it easier to maintain predictable braking characteristics and improves the comfort of the entire system.

SKU identification and vehicle fitment

The product has an assigned SKU, which facilitates unambiguous identification in the store system and during service communication. Combined with information about the placement on the vehicle, this allows for quickly verifying whether a given set corresponds to the rear axle configuration in a specific Mercedes W163 unit.

Before purchasing, it is worth comparing the part markings with the vehicle documentation or the numbers found on the currently installed components to confirm full compliance. Such an approach minimizes the risk of selecting the wrong component and speeds up the service process.

Braking system expansion and supporting materials

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

When selecting used braking system components, it is worth following a proven verification procedure.
