Purpose and Vehicle Placement

The presented brake caliper is designed for operation on the rear right side of the vehicle. It is responsible for evenly pressing the pads against the disc, which translates to stable braking of the rear axle. Correct placement on the vehicle is crucial for maintaining the proper geometry of the braking system and the even distribution of braking forces between the left and right sides.

Technical Characteristics of the Caliper

The brake caliper from the series used in Mercedes W209 models works with a disc measuring 290x36, allowing for efficient heat dissipation and stable operation under typical road loads. The construction includes:

• a rigid body ensuring adequate resistance to thermal deformation,
• pad guides enabling even wear of the brake pads,
• adaptation to the standard hydraulic system used in the Mercedes W209.

Thanks to this, the caliper can be used both in standard urban driving and in conditions of longer non-urban journeys, where the braking system operates within a wider temperature range.

Benefits of Using an Original Mercedes Caliper

Choosing an original Mercedes brake caliper allows for maintaining the factory parameters of the braking system. The most important advantages include:

• fitment with the suspension geometry and hub specific to the W209,
• compatibility with standard pads and discs measuring 290x36,
• maintaining predictable braking characteristics in line with the manufacturer's specifications.

For the user, this means consistent operation of the braking system without the need to modify other components, which simplifies servicing and subsequent inspections.

Condition, Verification, and Practical Application

The component comes from the secondary market, which helps to reduce service costs while maintaining a construction compliant with factory solutions. Before installation, the standard workshop procedure is recommended: checking for leaks, the free movement of the piston, and the condition of the surfaces cooperating with the pads. A correctly prepared caliper enables the restoration of full functionality to the braking system on the rear right axle of the vehicle.
