Purpose and compatibility with the brake system

The caliper housing has been designed specifically for the rear right side of Mercedes W213 series vehicles with the M256 petrol engine, compatible with a 360x26 brake disc. This ensures the correct geometry of the caliper relative to the disc, which reduces the risk of uneven pad wear and unwanted vibrations during braking.

The component belongs to the Brake calipers and brackets group, meaning it is responsible for the precise guidance of the moving parts of the caliper and their rigid mounting to the suspension. A correctly selected housing is crucial for maintaining the alignment of the disc and pads, and thus for the stable operation of the entire system.

Construction and function of the caliper housing

The caliper housing acts as a support for other components, such as guide pins, carriers, or mounting hardware. Its design ensures:

• adequate rigidity in the area of mounting to the steering knuckle,
• proper guidance of the brake pads relative to the disc,
• maintenance of a constant working distance between friction surfaces,
• stable caliper operation under high thermal loads.

By maintaining the original geometry, the housing works with the factory Mercedes brake system, which facilitates installation and helps avoid compatibility issues.

Characteristics of the used component

The presented housing comes from a used vehicle, which in practice means a favorable compromise between cost and maintaining the manufacturer's original specifications. For many users, this is a reasonable solution for brake system repairs, especially when they want to maintain the factory standard of workmanship and fitment.

Before installation, standard service procedures are recommended, such as cleaning contact surfaces, checking mounting threads, and verifying the condition of mating components (guide pins, bolts, pads, and discs) to ensure stable and predictable brake performance.

Benefits of using an original caliper housing

Using an original caliper housing in a Mercedes W213 with an M256 petrol engine allows you to maintain braking parameters in accordance with the manufacturer's specifications. The most important advantages include:

• Factory fitment – no modifications required, compatibility with the original brake system.
• Consistency with other system components – correct cooperation with the 360x26 disc and brake pads intended for this model.
• Possibility of economical repair – replacing only the caliper housing instead of the complete assembly.
• Maintaining predictable vehicle behavior during braking, especially at higher speeds.

Support with selection and additional materials

If you are planning a comprehensive repair or upgrade of the braking zone in your Mercedes and need other components from the same group, such as carriers, brackets, or complete calipers, check the available parts in the Mercedes Brake calipers and brackets category.

When choosing used brake system components, it is worth following proven inspection procedures.
