Purpose and Brake System Compatibility

The presented caliper belongs to the Brake Calipers and Brackets group and is designed for operation on the front axle, on the right side. The design adapted for a 322x32 mm disc allows for maintaining the correct pad-to-disc contact area, which translates into predictable, linear deceleration. Its placement on the vehicle as front-right side facilitates part selection during servicing and minimizes the risk of ordering errors.

Caliper Body Construction and Performance Characteristics

The TRW caliper body in this model has been developed for even distribution of braking forces across the entire pad surface. The appropriately selected geometry of the guides and pad seat promotes:

• stable pad guidance during intensive braking,
• maintaining uniform pressure against the disc,
• limiting the phenomenon of unilateral pad wear.

A caliper configured in this way works well with the factory Mercedes hydraulic system, maintaining braking characteristics consistent with the vehicle manufacturer's specifications.

Original Origin and Reference Numbers

This component is part of the Mercedes brake system and has a dedicated OEM part number and associated replacement numbers, which facilitates unambiguous identification in service catalogs. The presence of reference numbers allows mechanics and users to quickly verify compatibility with specific body versions and brake systems of the W204 and W212, as well as to compare with other caliper variants used in these models.

Condition, Application, and Benefits of Installation

The caliper is offered in used condition, which represents an attractive cost-effective solution while maintaining the original manufacturer's specifications. In many cases, installing such a component allows for:

• reducing the cost of brake system repair compared to a new part,
• maintaining the factory operating parameters of the system,
• avoiding fitment issues typical of aftermarket parts with different geometry.

For vehicles used intensively, including fleets, choosing an original caliper from disassembly can be a sensible compromise between durability and service budget.

Technical Support and Selection of Appropriate Calipers

When selecting a caliper for a specific version of the Mercedes W204 or W212, it is crucial to pay attention to its placement on the vehicle, the type of disc, and the reference numbers. This helps avoid installation problems and ensures proper cooperation with existing brake system components, such as discs and pads. If in doubt, it is advisable to compare the existing part with the manufacturer's catalog or consult a service specializing in the Mercedes brand.
