Purpose and vehicle placement

The presented brake caliper is designed to operate on the rear right side of the braking system. Its construction is compatible with the electric handbrake, allowing for precise control of the clamping force by the vehicle's control unit. Thanks to its dedicated placement, the correct geometry of the system is maintained, as well as proper interaction with the brake disc, pads, and brake line.

Technical and functional characteristics

As an original Mercedes component, the caliper has been designed for stable operation under demanding operating conditions. The housing and guide pins are adapted to work with the factory braking system, and the integrated electric parking brake module enables:

• automatic engagement and release of the parking brake,
• cooperation with vehicle safety systems,
• precise distribution of braking force on the rear axle.

This solution reduces the risk of uneven pad wear and supports vehicle stability during parking and starting, especially on inclines.

Service application and installation benefits

A used brake caliper with an electric handbrake is a practical choice for brake system repairs when the existing component has suffered mechanical wear or electrical damage. Using an original caliper from the same design group allows you to:

• maintain compliance with the factory brake system specifications,
• reduce installation time thanks to perfect fitment for mounts and lines,
• maintain proper interaction with the parking brake control electronics.

For workshops and users, this means predictable installation and a lower risk of system calibration issues after replacement.

Component condition and practical aspects

The product comes from disassembly and is offered as a used part, which represents a reasonable compromise between repair costs and maintaining the original design of the braking system. Before installation, a standard service procedure is recommended, including checking the working surfaces and guide pins, as well as properly bleeding the system after installation. In the case of calipers with an electric handbrake, it is also necessary to perform an adaptation procedure using an appropriate diagnostic tester.

Safe selection of used brake components

When choosing a used brake caliper, it is worth considering not only model compatibility but also the mechanical and electrical condition of the component.
