Brembo’s Latest Technology on Display at IAA


Brembo’s latest technology is on display at the IAA Commercial Vehicles show in Germany. The company is showing off its Electric Drum in Hat (EDIH) and Electric Parking Brake (EPB), among other products.

Read Brembo’s news about its EDIH and EPB below.


From 20 to 27 September, Brembo will be exhibiting the Electric Drum in Hat (EDIH) on its stand at the 67th IAA Commercial Vehicles exhibition, the important German trade show for commercial vehicles.

The Electric Drum in Hat is a “two-servo” brake with a specific electromechanical actuator designed to guarantee parking of commercial vehicles weighing up to 8 tonnes.

Patented by Brembo, the electromechanical actuator is a flagship achievement of the company’s research, development and testing of commercial vehicle braking systems. These systems are the result of continuous investment in research and development – amounting to 5% of company turnover – which leads to finding new mobility solutions for the future.

The integration of the vehicle electronic stability control system (ESC) guarantees the same functionalities as the ECS brake caliper. In fact, thanks to this technology, assistance is available for uphill starts and vehicle slip prevention, as well as manual/automatic parking brake release.

The system ensures safe parking even when the brake discs are hot. It can also be used as an emergency brake.

Brembo paid particular attention to the design of the electro-mechanical actuator in order to compensate the loss in EDIH lever load typical of duo-servo drum brakes. Another important feature is the total absence of drag in all conditions. This is possible through the monitoring of the EDIH lever position during release.

Further advantages of the Brembo EDIH are the possibility to release the parking brake manually in case of failure, and the capability to park the vehicle on a certain slope in case of failure of one of the two actuators.


Marking its participation in the 67th IAA Commercial Vehicles show, the important European event dedicated to the world of commercial vehicles that takes place from today till September 27 in Hannover, Brembo presents the Electric Parking Brake (EPB).

This electromechanical parking position system perfected by Brembo researchers replaces the parking brake, which is usually manually operated, by a mechanical lever in the driver’s cab. In Brembo’s EPB, all levers, cables and mechanical links are replaced by an electronic button located among the cab controls.

It is a solution that the international market is welcoming with enthusiasm because it simplifies the vehicle assembly and layout stages. However, it is commercial vehicle drivers who especially benefit from this system, as they are guaranteed more space in the cab, better ergonomics and less cognitive effort.

Always a prominent reference point in the braking system field, Brembo has a strong reputation for experimentation and research into technologies that can improve performance and comfort for both moving and stationary vehicles.

By integrating the EPB with the ESC (Electronic Stability Control) system, parking brake performance in the most critical conditions is now greatly improved compared to traditional solutions: its technology is capable of estimating brake disc temperature, road slope and other operating conditions.

The continuous diagnostics of all these variables and the system operating status by the electronic control unit automatically ensures a second activation of braking force in the event of a vehicle slipping. When, on the other hand, parking is carried out with very high caliper and pad temperatures, the system calibrates the optimum power.

To ensure the highest safety level in emergency situations, Brembo has equipped its EPB with a system that allows emergency braking with wheel anti-locking. This solution allows the driver to stop the vehicle safely should the hydraulic circuits of the calipers or drums stop working.

The distinctive trait of the EPB system is its combination of four elements: the control button in the cab, the software, the electronic control unit and the specific electromechanical actuators. Depending on the manufacturer’s requirements, the actuators can be applied to either the brake calipers or to the drum inside the brake disc (Drum in Hat).

As this is a safety-critical system, in other words, capable of managing increasingly more complex features, Brembo has dedicated particular attention to compliance with the prevailing regulations. The EPB has obtained ISO 26262 certification, the standard that regulates the use and functional safety of vehicle electrical and electronic systems.
