SFS develops customer-specific precision components and system solutions for modern brake booster applications. Combining expertise in mechanical actuation, force transmission, and high-volume manufacturing, we support the development of compact, efficient, NVH optimized and safety-critical brake booster systems for next-generation vehicles.
Brake Booster Systems
Brake booster systems reduce the force required from the driver to apply the brakes, helping to deliver responsive, controlled, and reliable braking performance. As vehicles become increasingly electrified and automated, conventional vacuum-assisted brake boosters are evolving into electrically actuated systems. They provide greater control, faster response, and improved integration with advanced vehicle functions.
How Brake Booster Systems Work
A brake booster increases the force generated by the driver’s brake pedal input, reducing the physical effort required to operate the braking system. In conventional vehicles, this assistance is commonly provided through a vacuum-based system that uses pressure differences to amplify the force applied to the brake master cylinder.
Modern brake booster systems increasingly use electric motors and electromechanical actuation to generate braking assistance. These systems provide precisely controlled braking force independently of engine vacuum, making them particularly well suited to hybrid and electric vehicles.
By combining electronic control with high-performance mechanical actuation, electric brake boosters support faster system response, shorter braking distance, improved braking control, and integration with advanced driver assistance systems.
The Evolution From Vacuum to Electrical Brake Boosters
Conventional vacuum brake boosters have been widely used in automotive braking systems for decades. However, the transition towards electrified powertrains is reducing the availability of engine-generated vacuum, increasing the need for alternative braking assistance technologies.
Electrical brake booster systems use electronically controlled actuators to generate and regulate brake assistance. This enables greater flexibility in how braking force is applied and supports functions such as regenerative braking, automated emergency braking, and advanced driver assistance systems.
Electric actuation can also improve system efficiency and enable more compact, highly integrated brake architectures. As vehicle automation continues to develop, brake booster systems are expected to play an increasingly important role in connecting driver input, electronic control, and mechanical braking performance.
Precision Components for Brake Booster Systems
Modern electric brake booster systems rely on precisely engineered mechanical components to convert motor-driven rotational movement into controlled linear force. The performance of these components directly influences system response, force transmission, efficiency, and long-term reliability.
As vehicles become quieter through electrification, NVH (Noise, Vibration and Harshness) is gaining importance. With expertise in NVH analysis and problem solving, we can fine-tune designs to meet customer requirements.
SFS develops customer-specific precision solutions for demanding brake booster applications. Our portfolio includes high-performance ball screw drives, formed components, connection elements, and integrated assemblies designed to meet the requirements of compact and highly loaded automotive systems.
Through expertise across multiple manufacturing technologies, SFS supports individual components or integrated system solutions. This approach enables optimized interfaces, efficient assembly, and application-specific designs tailored to the performance requirements of each brake booster architecture.
One-Box and Two-Box Brake Architectures
Electrohydraulic braking systems can be designed using different system architectures. In one-box systems, braking assistance, pressure generation, and electronic control functions are integrated into a compact unit. Two-box systems separate the brake booster and hydraulic control functions such as ABS and ESP into individual modules.
Both architectures place demanding requirements on component performance, packaging, and system integration. Components must deliver reliable force transmission while operating within compact installation spaces and under high mechanical loads.
Our Engineering and Manufacturing Expertise
Brake booster components must meet demanding requirements for precision, strength, durability, and repeatable performance. Achieving these characteristics requires close coordination between component design, material selection, manufacturing technology, and system-level functionality.
Our technology portfolio enables customer-specific components to be developed for complex brake booster applications while supporting efficient, high-volume automotive production.
By engaging early in the development process, SFS contributes manufacturing expertise and application knowledge to help optimize component performance, production efficiency, and overall system integration.
