Technical Characteristics and Purpose

The presented assembly belongs to the category of Brake Boosters and Force Regulators and is a key element of the hydraulic part of the braking system. The servo uses vacuum to amplify the force applied to the brake pedal, and the integrated master cylinder distributes pressure to individual brake circuits. The brake fluid reservoir allows for monitoring the working fluid level and its stable supply.

The complete servo-master cylinder-reservoir construction reduces the risk of incorrect selection of individual components and facilitates installation in Mercedes C-Class W205 vehicles equipped with this type of factory solution.

Advantages of Using an Original Brake Assembly

Choosing an original servo and master cylinder assembly for the Mercedes W205 ensures:

• maintenance of factory brake pedal characteristics,
• correct braking force modulation across the entire vehicle load range,
• consistency with the factory brake system architecture,
• easier diagnostics in case of potential malfunctions.

Additionally, the presence of the fluid reservoir in a single unit with the servo and master cylinder simplifies servicing and reduces the number of connections that could be potential leak sources.

Condition, Origin, and Installation Aspects

The component comes from the Mercedes line and is a used part, allowing for economical repair while maintaining original construction. The assembly is intended for installation in place of the factory servo with master cylinder, using existing mounting points and brake lines provided for this configuration.

Before installation, standard service procedures are recommended: leak testing, replacement of brake fluid with fresh fluid, and thorough bleeding of the system according to the vehicle manufacturer's procedure. A correctly installed assembly restores stable brake system operation and improves brake pedal comfort.

Part Selection by Numbers and Compatibility

The presented brake servo assembly with master cylinder and reservoir has a dedicated OEM part number and associated interchangeable numbers, which facilitates precise identification in manufacturer catalogs. This allows for matching the component to a specific engine and equipment version of the Mercedes C-Class W205 without the risk of error.

Before purchasing, it is advisable to compare the markings with the vehicle documentation or the removed part to confirm full compatibility. This selection method minimizes the risk of installation problems and ensures correct interaction with other brake system components and safety systems.

Brake System Expansion and Used Part Care
