Purpose and fitment for the brake system

The caliper housing has been designed specifically for the rear left side of Mercedes W213 class vehicles with the M256 petrol engine, compatible with 360x26 discs. This structural fitment allows for maintaining the correct geometry of the caliper relative to the disc, which is essential for even pad pressure and braking stability at higher speeds.

The component belongs to the Brake calipers and brackets group, making it a perfect fit for the factory architecture of the Mercedes brake system. Installation is performed in the location specified by the manufacturer, without the need for modifying mounts or interfering with the suspension structure.

Construction and function of the caliper housing

The caliper housing plays a key load-bearing role for the braking mechanism – it is responsible for guiding the brake pads, maintaining the correct position relative to the disc, and transferring braking forces to the steering knuckle. In the case of the 360x26 disc, appropriate body rigidity is crucial to limit deflection and ensure uniform pressure across the entire working surface.

The solution used in the W213 with the M256 engine was developed with high thermal and mechanical loads in mind, typical for modern high-power petrol units. As a result, the housing works well with both standard and more demanding brake pad sets, maintaining operational stability over a long service life.

Benefits of using an original caliper housing

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

• Factory fitment – maintaining the correct position of the caliper relative to the 360x26 disc without the need for adjusting components.
• Stable rear axle operation – even pad wear and predictable brake system response.
• Compatibility with safety systems – proper interaction with brake assist systems that rely on the factory caliper geometry.
• Cost-effective repair option – replacing only the caliper housing instead of the complete assembly when other components are still functional.

Characteristics of the used component

The caliper housing comes from dismantling, which allows you to combine the original Mercedes construction with a more favorable repair cost. The used component retains factory mounting points and geometry, which is particularly important for the rear left side of the vehicle, where the brake system interacts with electronic stability control systems.

For many users, choosing such a solution represents a reasonable compromise between quality and budget – especially for repairs where it is crucial to maintain the original technical specification without having to resort to aftermarket parts with uncertain fitment.
