A Disk brake rotor play a critical role in modern automotive braking systems, providing the essential mechanism for converting kinetic energy into thermal energy, thereby facilitating vehicle deceleration. This abstract delves into the fundamental principles, design considerations, materials, and performance characteristics of disk brake rotors. Firstly, the abstract elucidates the operating principles of disk brake rotors within the context of automotive braking systems. It explores how the rotational motion of the wheel translates into frictional forces acting on the rotor surface, generating heat that dissipates through conduction and convection.Secondly, it discusses the key design considerations influencing the efficiency and reliability of disk brake rotors. Factors such as rotor diameter, thickness, ventilation, and surface geometry are analysed for their impact on heat dissipation, wear resistance, and braking performance. Furthermore, the abstract addresses the materials commonly employed in disk brake rotor construction. Traditional materials like cast iron are contrasted with newer alternatives such as carbon-ceramic composites, examining their respective advantages in terms of weight, thermal conductivity, durability, and cost. Moreover, the abstract explores the performance characteristics of disk brake rotors under various operating conditions. It discusses phenomena such as brake fade, hot spotting, and thermal deformation, elucidating the factors contributing to rotor wear and degradation over time

“…"little-known socio-environmental problem", which is as terribly damaging as moped emissions. Where, the grey-iron (GI), its base material (pad/disc) is effective; and shouldn't be altered; considering its operability within the standards (Tonolini et al, 2021). According to Djafri et al (2014), GI presents good shear and wear resistance, with an easy-workability at foundry.…”

The whole world depends on land vehicles such as trucks, cars and motorcycles to meet essential demands. As a result, PM2.5’s emissions become to centre attention; being that, 20% comes from brake-disc and pad friction. In view of this problem, this paper presents a new method for brake-discs laser cladding; using nickel (coating) and rotation system. To this end, was used the high-speed laser application system (EHLA); consisting of: an ytterbium laser, robotic arm, rotating shaft with stepper motor and coat powder aspersion system. The results shown a viability of this technique. With the following parameters: tangential velocity of scanning “vs” 9-11mm/s, power efficiency “E” of 70-75% and deposition rate “µ” of 4g/min. Producing homogeneous, well-anchored coatings. With high densification.

“…Numerous test systems have been proposed and adopted in the automotive sector (but also in other sectors, for example, railways [8][9][10]), each distinguished by the test procedures, experimental setups, and samples they adopt [11]. Generally, testing machines can be categorized into three main types based on whether the experimental tests are conducted using a pin-on-disc (or block-on-ring) configuration [12][13][14][15][16], a brake dynamometer (also called inertia dynamometer) [17,18], or a roller chassis bench (also called chassis dynamometer) [6,19]. Clear and useful overviews of the main testing systems, along with a concise history of the development of automotive brake test systems, are available in [20,21].…”

The optimization of the brake systems is crucial for vehicle performance and safety of Formula SAE (FSAE) race cars. This study introduces a specialized brake test bench designed to enhance the understanding and testing of these systems. The bench integrates a rotating mechanical system mounting a brake disc-caliper group, which is driven by an electric motor, a pneumatic brake pedal assembly to simulate real braking conditions, and a comprehensive array of sensors that facilitate the measurement of critical parameters, such as rotation speed, braking torque, oil pressure, and disc temperature. Its structure, sensor integration, and control electronics are fully described, demonstrating the capability to replicate on-track scenarios in a controlled environment. The results underscore the utility of the bench in providing precise and consistent testing conditions essential for analyzing the efficiency, durability, and safety of the braking systems of FSAE race cars.
