The electromechanical brake (EMB) is an innovative technology increasingly used in modern vehicles. It replaces the traditional hydraulic braking system with an electronically controlled system. This article explains how electromechanical brakes work, their advantages, and common issues.
What is an Electromechanical Brake?
The electromechanical brake is a braking system that controls the braking process using electrical signals instead of hydraulic pressure. Instead of a brake pedal directly connected to the master cylinder, the EMB uses sensors and control units to regulate the braking force electronically. Dr. Hans Müller, author of “Modern Braking Technologies,” emphasizes: “The EMB offers more precise and efficient braking performance compared to traditional systems.”
At the heart of the EMB is an electric motor that presses the brake pads directly onto the brake disc. This system allows for faster response times and more precise brake force modulation. The EMB also plays a crucial role in advanced driver assistance systems such as ABS and ESP.

Advantages of Electromechanical Brakes
The EMB offers numerous advantages over traditional hydraulic braking systems. These include:
- Faster Response Time: Electronic control enables a significantly faster response time compared to hydraulic systems.
- More Precise Brake Force Modulation: The EMB can modulate the braking force very precisely, ensuring optimal braking performance.
- Improved Safety: Integration with driver assistance systems such as ABS and ESP enhances driving safety.
- Reduced Wear: Precise control of the braking force reduces wear on the brake pads.
- More Environmentally Friendly: The elimination of brake fluid makes the EMB more environmentally friendly.
Common Problems and Troubleshooting
Despite their advantages, electromechanical brakes can also experience problems. Here are some common issues and troubleshooting tips:
- Sensor Faults: Defective sensors can lead to malfunctions of the EMB. In this case, the error message in the fault memory should be read out, and the defective sensor replaced.
- Control Unit Faults: A defective control unit can also cause problems. Replacement of the control unit is usually necessary here.
- Software Errors: Sometimes, software errors can be the cause of problems with the EMB. A software update can fix the problem.

Maintenance of Electromechanical Brakes
The EMB requires less maintenance compared to traditional braking systems. Nevertheless, regular checks should be carried out to ensure functionality. “Regular inspections are crucial for the safety and longevity of the EMB,” explains engineer Franz Wagner in his book “Electromechanical Braking Systems in Practice.”
Electromechanical Brake vs. Hydraulic Brake
Compared to hydraulic brakes, the EMB offers many advantages, such as faster response times and more precise brake force modulation. However, the EMB is also more complex and more expensive to repair.
