Technical Characteristics of the Brake Booster and Master Cylinder Module

The presented module combines a brake booster and a master cylinder in a single housing, creating a compact and functional brake system component. This design reduces the number of hydraulic connections, which helps maintain seal integrity and simplifies diagnostics. The use of a factory-original solution ensures proper integration with the ABS/ESP system and other brake system components in the W166 body.

Original manufacturing in accordance with vehicle manufacturer standards allows for the preservation of correct pedal travel parameters, assistance characteristics, and linear response to pressure. This provides the driver with predictable vehicle behavior during braking, both in everyday use and in emergency situations.

Application and Fitment for Mercedes W166

The Brake Booster and Brake Force Regulator in this configuration have been specifically designed for the W166 platform, taking into account engine bay geometry and brake line routing. Installation in place of the factory component requires no structural modifications, which simplifies workshop procedures and reduces vehicle downtime.

The module belongs to the Brake Boosters and Brake Force Regulators category, meaning it is responsible not only for assistance but also for the correct distribution of pressure in the brake circuits. This ensures system stability during hard braking, even with varying vehicle loads.

Benefits of Using an Original Brake Module

Choosing an original part from disassembly is a technically and economically advantageous solution. The module retains factory operating parameters while allowing for cost savings compared to a new part. Key benefits include:

• preservation of factory brake pedal and assistance characteristics,
• proper integration with vehicle electronics (stability control and ABS systems),
• fitment with factory mounting points and lines,
• reduced risk of compatibility issues compared to low-quality aftermarket alternatives.

By using an original module, the driver benefits from consistent operation of the entire braking system, which directly impacts driving safety and vehicle comfort.

Condition, Verification, and Operation of a Used Part

This component is from disassembly and is offered as a used part, requiring a conscious approach to installation and further operation. Before installation, it is recommended to thoroughly inspect the system for leaks, the condition of the brake lines, and the quality of the brake fluid. Proper installation and bleeding of the system are crucial for the module's full functionality.

To extend the reliable service life of such a component, regular brake fluid changes and periodic checks of the entire system are advisable.
