Function and Role in the Braking System

The vacuum hose connecting the brake booster to the engine's vacuum system is responsible for maintaining the correct vacuum level in the booster chamber. This allows the driver to feel significant assistance when pressing the brake pedal, and the braking force is more controllable.

In practice, a functional hose:

• ensures stable brake assistance across the full range of engine loads,
• reduces the risk of reduced braking effectiveness during sudden braking,
• minimizes the possibility of leaks in the vacuum circuit.

Fitment and Installation in Mercedes E-Class W213 / S213

The offered part has been specifically designed for the brake booster system in the Mercedes E-Class W213 generation and the S213 estate version. This means factory routing of the hose, appropriately sized connectors, and compatible ends for working with the vacuum pump and brake booster.

Key installation advantages include:

• original geometry tailored to the engine bay of these models,
• retention of factory mounting points and hose routing,
• minimization of modifications required when replacing with an OEM part.

Benefits of Using an Original Vacuum Hose

Choosing an original vacuum hose from the Brake Boosters and Force Correctors category allows you to maintain braking system operating parameters in line with the manufacturer's specifications. Unlike aftermarket alternatives with universal geometry, a factory part ensures proper positioning relative to other components in the engine bay, reducing stress and potential leaks.

Key benefits include:

• stable brake assistance due to correct vacuum flow,
• better repeatability of braking force during daily use,
• compliance with factory Mercedes service procedures.

Condition and Service Application

The component is offered as a used part, enabling economical repair of the brake assist system while maintaining original specifications. This type of hose is particularly useful for:

• addressing leaks in the brake booster vacuum circuit,
• diagnosing issues with a hard brake pedal,
• comprehensive servicing of the Brake Boosters and Force Correctors system in Mercedes W213 / S213.

If you are planning a comprehensive repair or upgrade of the braking area in your Mercedes and need other parts from the same group, such as a brake booster, brake force corrector, or additional vacuum hoses, check the available parts in the Mercedes Brake Boosters and Force Correctors category.

Safety in Selecting Used Brake System Components

When choosing used brake system components, such as vacuum hoses, boosters, or correctors, it is crucial to pay attention to sealing, connector condition, and compatibility with the specific model version. Proper part selection helps avoid problems with uneven assistance and extended braking distances.

To better prepare for the purchase and installation of used brake components, it is advisable to consult practical tips and checklists described in the article Second-Hand Braking Systems: How to Safely Choose Discs, Calipers, and ABS?. Additionally, in the context of general vehicle maintenance and selecting used OEM components, the guide Air Conditioning and Heating – Part Selection and Maintenance for Year-Round Comfort, which discusses best service practices when working with original components, may be helpful.
