Purpose and function in the braking system

The presented brake servo integrated with the master cylinder has been designed specifically for the luxury Mercedes-Benz CL-Class C215 and S-Class W220 models. It is responsible for increasing the pressure force on the brake pedal and precise dosing of pressure in the brake circuits, which is crucial for heavy, powerful vehicles of this class.

This element works with the vacuum assistance system and brake hydraulics, ensuring:

• stable brake pedal characteristics,
• repeatable braking force during successive applications,
• proper cooperation with other braking system components.

Advantages of using an original Mercedes servo

• precise fit to the mounts and geometry of the engine compartment,
• proper cooperation with factory brake lines and accessories,
• compliance with factory brake force correction settings.

Thanks to this, installation proceeds in a predictable manner, without the need for modifications or adaptations, and the braking system retains the characteristics intended by the manufacturer.

Product characteristics and condition

The offered element comes from a Mercedes vehicle and is classified as a used original component. This is a good solution in situations where you want to maintain factory quality while optimizing repair costs. The product is intended for professional installation in a specialized service center or by an experienced mechanic, in compliance with procedures for bleeding and checking the tightness of the braking system.
