Purpose and technical fitment

The presented caliper is designed specifically for operation on the front, right side of Mercedes W204 series vehicles, in conjunction with a 295x28 brake disc. This structural fitment allows for maintaining the correct system geometry, even pad pressure, and proper interaction with the factory brake master cylinder and brake booster.

The original Mercedes origin ensures compliance with factory quality standards, appropriate caliper body rigidity, and correct placement of mounting points. As a result, this component can be used as a replacement for a damaged caliper without the need for modifying the steering knuckle or lines.

Construction and function in the braking system

The caliper is responsible for converting hydraulic pressure into the force that presses the pads against the disc, which is why its construction must ensure stable operation under high temperatures and heavy loads. The body is adapted to work with a disc of a specific diameter and thickness, which minimizes the risk of uneven pad wear and vibrations during braking.

Precise pad guidance and properly selected support points allow for maintaining uniform pressure across the entire working surface. Proper fitment of the caliper to the specific axle and side of the vehicle is crucial for maintaining the symmetry of braking forces, and thus for vehicle stability during intense emergency braking.

Benefits of using an original caliper

Using an original caliper in a Mercedes W204 provides several significant technical benefits:

• maintenance of factory braking characteristics and system efficiency,
• secure fitment to the steering knuckle, disc, and pads without modifications,
• compatibility with factory-associated components (lines, mounts, shields),
• reduction of the risk of uneven pad and disc wear.

For the user, this means predictable brake operation, easier diagnostics, and the possibility of future maintenance in accordance with the manufacturer's documentation.

Condition, verification, and purchase safety

The item comes from disassembly and is offered as a used brake caliper, which allows for optimizing repair costs while maintaining factory specifications. Before being offered for sale, such components are standardly verified for body integrity, mounting threads, and general suitability for further use.
