Purpose and vehicle placement

The presented set of discs is designed for installation on the rear wheels, with dedicated placement for both the right and left sides. This solution allows for the simultaneous replacement of both discs on the axle, which is recommended for safety, braking stability, and even brake pad wear.

These components work with the factory Mercedes braking system, maintaining proper performance parameters such as braking efficiency, resistance to overheating, and predictable behavior during intensive use.

Technical characteristics of the set

The rear disc set has been developed as an original part, compliant with the vehicle manufacturer's requirements. The appropriate geometry of the working surface and the fitment to the hub and brake caliper translate into:

• stable transfer of braking force on both rear axle wheels,
• proper cooperation with standard brake pads,
• maintenance of the correct operating characteristics of the ESP/ABS system.

The choice of material and design of the discs in this reference is optimized for operation in Mercedes SUV class vehicles, where the braking system works under higher loads than in lighter passenger cars.

Condition of the item and benefits of choosing used parts

The offered set comes from the used brake discs category, which allows for a significant reduction in rear axle maintenance costs while maintaining the original manufacturer's specifications. For many Mercedes W164 and X164 users, this is a reasonable compromise between quality and budget, especially during comprehensive brake system maintenance.

The choice of original, used brake components is often preferred by workshops specializing in the Mercedes brand due to proper fitment, predictable behavior in operation, and compliance with the vehicle's factory parameters.

Safety, selection, and operation

To fully utilize the potential of this set, it is recommended to install them in pairs on one axle and to check the condition of the brake pads, calipers, and brake lines. Proper installation and bedding-in of the discs with the pads contribute to:

• shortening the braking distance in typical road conditions,
• vehicle stability during emergency braking,
• reducing the risk of vibrations and judder on the brake pedal.
