Purpose and function in the brake system

The offered vacuum pipe is the component connecting the brake servo to the vacuum generation system, ensuring proper assistance for the brake pedal pressure force. Installation on the right side of the vehicle allows for maintaining the factory routing of the pipe, which reduces the risk of incorrect positioning, chafing, or leaks.

In practice, a correctly selected vacuum pipe contributes to:

• stable operation of the brake servo across the full load range,
• consistent brake pedal feel,
• maintaining the factory performance parameters of the brake system.

Advantages of using an original Mercedes pipe

As a Mercedes brand component, the pipe has been designed for specific C118, W177, and W247 models, maintaining the correct geometry, internal diameter, and mounting points. Thanks to this:

• it fits factory brackets and connectors without the need for modifications,
• it maintains the tightness of the vacuum system under road operating conditions,
• it reduces the risk of installation errors typical of universal replacements.

A used OEM element is also a way to maintain the original brake system specification while lowering service costs compared to a new part from an authorized dealership.

Condition, fitment, and installation aspects

The pipe comes from disassembly and is offered as a used part, which allows for an economical repair without compromising the manufacturer's original design. The location on the right side of the vehicle facilitates the identification of the correct element when comparing it with the existing installation in the car.

When selecting a vacuum pipe for the brake servo, it is worth paying attention to:

• compatibility with the specific body generation (C118, W177, W247),
• correct shaping of the pipe sections relative to the engine bay,
• the condition of connectors and ports in terms of tightness after installation.

Such a configured selection reduces the risk of vacuum loss, and consequently, a decrease in brake booster efficiency.
