Brake Systems

Modern automotive braking systems combine mechanical, hydraulic, and electronic components to ensure safe and controlled vehicle deceleration. Core brake system components include hydraulic control units, anti-lock braking system (ABS) modules, electronic stability control (ESC) systems, and brake booster assemblies (EHB). Within these systems, precision parts such as solenoid valves, sensors, and structural elements regulate brake pressure and maintain vehicle stability under dynamic conditions. As braking systems evolve, there is an increasing shift towards electromechanical braking architectures, where traditional hydraulic elements are complemented or replaced by electronically controlled actuation systems.

ABS (anti-lock braking systems) and ESC (electronic stability control) are key subsystems within modern braking architectures, designed to improve vehicle control and safety. These systems rely on a combination of sensors, electronic control units (ECUs), and hydraulic control units to continuously monitor and adjust braking force. Hydraulic control units, including integrated solenoid valve and pump components, regulate brake fluid pressure to prevent wheel lock-up and maintain traction. ESC systems build on this by selectively applying braking force to individual wheels, ensuring stability during cornering or sudden maneuvers. The performance of these systems depends heavily on the precision and reliability of the underlying brake system components.

Brake booster parts are responsible for amplifying the force applied by the driver, reducing the effort required to operate the braking system. Driven by vehicle electrification and the reduced availability on combustion engine vacuum sources, traditional vacuum-assisted systems are increasingly being replaced by modern brake booster solutions. These are progressing further towards electric brake booster systems that utilize electromechanical actuation. These systems enable faster response times, improved efficiency, and seamless integration with advanced driver assistance systems (ADAS). As a result, brake booster architectures are becoming more compact, precise, and electronically controlled, requiring high-performance components designed for both mechanical strength and system integration.

Electromechanical braking (EMB), often referred to as brake-by-wire, represents the next generation of automotive braking systems. In these systems, traditional hydraulic connections are reduced or eliminated, and braking is controlled through electronic signals and actuators. EMB systems rely on a combination of sensors, control units, and precision mechanical components to deliver accurate and responsive braking performance. This shift towards fully electronic braking architectures supports increased vehicle automation, improved system efficiency, and greater design flexibility, while also placing higher demands on the precision and reliability of individual solutions.

Ball screw drives are a key enabling technology in electric brake booster systems and electromechanical braking (EMB) applications. They convert rotational motion into precise linear movement, allowing accurate control of braking force and actuator positioning. In braking systems, ball screw drives support efficient force transmission, high load capacity, and repeatable performance, making them well-suited for safety-critical applications. As braking systems continue to evolve towards electromechanical designs, the importance of ball screw drive technology in automotive braking applications is expected to grow significantly.

Brake system components are produced using advanced manufacturing technologies to meet strict safety, performance, and quality requirements. Processes such as cold forming, plastic injection molding, precision machining, and specialized secondary operations enable the production of high-strength, complex products with tight tolerances and consistent performance. These technologies are particularly important for solutions used in hydraulic control units, solenoid valve systems, and electromechanical actuation systems, where reliability and durability are critical.
