We anticipate the braking system to perform flawlessly under diverse weather conditions, whether it’s navigating downhill on a brisk morning or enduring scorching afternoons. Hence, selecting the appropriate components for the friction material blend intended for linings is crucial. Each step of the manufacturing process of the product is significant to ensure adequate resistance to wear while maintaining consistent adhesion parameters (friction coefficient). Consequently, both the components and the manufacturing process remain confidential, with manufacturers dedicating considerable time and resources to laboratory testing. This commitment also extends to MILES products, ensuring compliance with even the most stringent regulations.
Compliance with ECE R90 Standards
Prior to the launch of MILES products onto the market, comprehensive brake performance tests are conducted in accordance with the ECE R90 standard. These tests encompass various conditions such as cold, high temperatures, fading, and cooling intervals, aiming to assess performance characteristics even under intense usage. One significant aspect scrutinized during these evaluations is the tendency for the friction coefficient to decrease as linings heat up due to gas release from the friction material. It’s imperative that the results of tested friction linings do not deviate from those of original parts by more than 15%.
Furthermore, within the framework of ECE R90 requirements, the shear resistance and pressure resistance of the linings are assessed to mitigate the risk of detachment or chipping during braking. For instance, brake linings should withstand shearing forces of at least 1.4 N/cm2. The quality of the bonding process between the lining and the metal plate during production plays a pivotal role in this regard.
Additionally, stationary tests known as Krauss tests are employed to gain further insights into the linings and to compare the quality of different friction materials. These tests subject the linings to increased loads, test frequencies, and braking system temperatures, accelerating wear processes while assessing their performance under critical conditions. The measurement system tracks the friction coefficient based on brake applications and lining temperatures.
Given the static nature of this testing method, it not only allows for friction coefficient measurement but also facilitates examination of lining wear and noise levels of the brakes. MILES products undergo rigorous testing, ensuring mechanics install top-quality parts and enabling drivers to safely operate their vehicles.
