Mercedes C238 E53 AMG M256 Brake Caliper Right O/S Housing 360x26 A0004237600

Mercedes C238 E53 AMG M256 Brake Caliper Right O/S Housing 360x26 is an original brake system component designed for gasoline-powered vehicles, engineered for stable, consistent braking in high-performance cars. This component from the Brake Calipers and Brackets group ensures precise pad positioning relative to the disc and provides the necessary rigidity for the entire system. Thanks to the factory AMG design, the correct braking characteristics are maintained, tailored to the weight and dynamics of the E53 model.

Purpose and technical specifications

The presented caliper is designed for installation on the right side of the vehicle, in a system compatible with a 360 mm diameter and 26 mm thick brake disc. The construction, intended for use in a gasoline-powered car, allows for efficient heat dissipation and stable operation during the repeated, heavy braking typical of the M256 unit in the AMG version.

The geometry of the caliper is matched to the factory suspension and hub, which promotes proper positioning relative to the disc and even pad pressure. The appropriately selected cylinder working volume ensures consistent brake pedal feel and predictable system response.

Benefits of using an original AMG caliper

Using an original caliper in the E53 AMG model allows you to maintain factory braking characteristics without the risk of unwanted changes in front-to-rear balance or the operation of assistance systems. Key advantages include:

• Compatibility with the factory brake system – maintaining proper interaction with the disc, pads, and ABS/ESP system.
• Constant, repeatable braking force under high thermal loads.
• Adequate body rigidity, limiting deflection under high system pressure.
• Direct fitment as a replacement for a worn or damaged part, without the need for installation modifications.

Condition, verification, and practical application

This item comes from the used original parts segment, which allows for a reasonable cost while maintaining factory AMG specifications. Before installation, a standard workshop inspection is recommended, including an assessment of working surfaces, threads, mounting points, and hydraulic system tightness. Caliper replacement is particularly recommended in the event of:

• uneven pad wear on the right side,
• seizing of guide pins or pistons,
• mechanical damage following a collision or system overheating.

A properly selected, original right-side caliper helps restore even axle braking, reduce vibrations, and improve vehicle stability during intense deceleration.

Integration with the Mercedes AMG brake system

In E53 AMG class cars, the brake system is designed as a cohesive unit where the caliper, disc, pads, and electronic control form a matched set. Replacing the caliper with a factory-spec component allows you to maintain:

• proper interaction with active safety systems,
• stable vehicle handling when braking from high speeds,
• adequate fade resistance under dynamic driving conditions.

This approach is particularly important in high-power cars, where the brake system operates at elevated temperatures and under high mechanical stress.
