Brake Caliper Mercedes SLK R171 Front Right O/S Carrier 57 300X28 A0044203283

The Front Right Brake Caliper for Mercedes SLK R171 is an original brake system component, designed for installation on the driver's side at the front of the vehicle. Its factory design ensures proper cooperation with a disc of the appropriate diameter and thickness, stable pad guidance, and even transfer of braking force. This is a solution for users who expect consistency with the factory Mercedes specification and want to maintain predictable vehicle behavior during braking.

Intended Use and Vehicle Placement

The presented caliper is designed to operate on the front axle, right side, which is crucial for correct brake force distribution and compatibility with the steering knuckle mounting. The support structure and mounting point layout are adapted to the brake system geometry of the Mercedes SLK R171 generation, facilitating installation and minimizing the need for additional modifications.

Selecting the correct caliper for a specific side of the vehicle is important not only due to the bolt spacing but also for the proper positioning of the bleeder screw and brake line routing. This model has been prepared precisely for such a configuration, promoting hassle-free servicing.

Construction and Technical Characteristics

The front brake caliper for the SLK R171 utilizes a carrier with an appropriately selected working width, designed to cooperate with a ventilated disc of a specific thickness. This configuration allows for:

• stable guidance of brake pads in the caliper bracket,
• even pressing of the pads against the disc's working surface,
• maintaining the correct working clearance between the pad and the disc after releasing the brake pedal.

This solution supports consistent braking force and reduces the risk of friction element overheating during dynamic driving. The original Mercedes design also contributes to maintaining the overall rigidity of the assembly, resulting in precise pedal feel.

Practical Application and Benefits of Installation

Installing this caliper is particularly beneficial in situations where the existing component shows signs of wear, such as uneven pad wear, seized guide pins, or a decrease in braking effectiveness on one side. Replacing it with an original caliper of the correct specification allows for:

• restoring the symmetry of the brake system's operation on the front axle,
• reducing vibrations and vehicle pulling during braking,
• maintaining compliance with Mercedes' original design intentions.

This solution is suitable for both standard operation and for vehicles used more dynamically, where braking stability and consistency are of great importance for safety.

Condition, Origin, and Parts Selection

This component comes from the original Mercedes parts line, meaning it retains factory geometry, materials, and manufacturing standards. As a used part, it offers a good compromise between repair costs and maintaining compliance with OEM solutions, especially for models where the brake system is precisely tuned to the suspension characteristics.

Before purchasing, it is advisable to verify compatibility with the specific engine version and model year of the SLK R171, using the OEM part number and interchangeable numbers available in the technical specifications. This helps avoid installation issues and ensures full compatibility with the existing disc and pads.
