Job title



Understanding and identifying the deficiencies of the elements or systems in the automotive market is the elementary procedure for developing new technologies and creating a product that improves the current characteristics. In the field of braking systems, we find in the last 100 years, two predominant systems, the brake drum and the brake rotor disc. The drum was widely installed for the first 30 years, based primarily on its easy actuation, and the durability of the brake shoes. Over the last 60 years the vehicle has been evolving, to more reliability, performance and safety by the OEM's, this has resulted in an increasing mass and power of the vehicles, so the adoption of the rotor disc brake as the predominant technology, was necessary as the performance and controllability needs of the brake have been increasing substantially. Even in the last 20 years, high industrial cost solutions such as carbon in discs and pads have been used. Over the last 10 years, environmental needs and regulations have grown exponentially to prevent damage to people's health and environmental pollution. Nowadays, non-exhaust particles emitted by current vehicles represent the highest percentage of total emissions, for example, in BEV's, exhaust emissions represent 0%, while non-exhaust emissions represent 100% of the total. This paper focuses on how the BRL brake, thanks to its design and mechanical characteristics, provides substantial advantages in performance, durability, controllability and significantly of brake emissions versus current systems. The methodology for addressing the objective performance and emission improvements of the braking system, is based on the design and mechanical characteristics. The same current friction technology is maintained, but with a reduction in both brake mass and rotating mass, improved thermodynamic management without compromising PM2.5 and PM10 particle filtration, no residual drag, increased life cycle, fine controllability in both axial directions, and simplification of processes in the assembly line and dynamic advantages. The main parameters tested are repeatability, controllability, torque vs. pressure stability, consistency at different speeds and temperature. The packaging options offered by the BRL brake are categorized by; Cooling types: Liquid and forced air; Actuation types: Hydraulic /EHB, pneumatic and by wire (dry EMB); Materials and components: High modularity, use of standard market materials and friction surface; Mass distribution: suspended and unsprung mass installation. All in all, the BRL braking system, with its technical qualities and results, presents a product with mechanical characteristics that are in line with the current needs of the market in terms of performance, thermodynamic management, environmental, by wire actuation and safety. BRL can be incorporated applied for both i) high performance braking applications (commercial, military, competition, high performance passenger vehicles) and ii) lower performance braking systems such as light passenger vehicles.
