A two-piece type with the rotor and bell housing separated is adopted, and special carbon is uniformly blended into the rotor material using our unique technology. As a result, a stable friction coefficient was obtained with less cracking, and we succeeded in fully drawing out the performance of the brake pads. In addition, duralumin, which is resistant to heat and has high strength, is used for the bell housing. While contributing to stable braking force, it also reduces unsprung weight. Benefits of enhanced cooling performance Our 2-piece brake rotor has been devised in terms of vane shape, etc. in order to improve cooling performance. This makes it possible to suppress the temperature rise under high load. Under the same load conditions, we compared the rotor temperature and friction coefficient between the genuine A company φ370 x 34 mm thick rotor and the ENDLESS genuine replacement 2P type φ370 x 34 mm thick (84 vanes), and confirmed a difference of 200 ° C in the rotor temperature. A difference of 0.1μ was confirmed even on the brake pads. By using a brake rotor with high cooling efficiency, it is possible to prevent the rotor temperature from rising and to maintain the proper temperature range of the brake pads. * A difference of 0.1μ in friction coefficient is a difference that anyone can experience due to the effectiveness of the brakes. * The number below the graph is the number of times pressure is applied. * Our brake rotor compared to the genuine rotor is \"ERI-006\". * The results of this data differ depending on the usage method and environment, and we do not guarantee the same results as this data. Please note. ![](\/\/cdn.atomic-shop.com\/images\/product\/516\/516358\/data.jpg)The image below is an image of the brake pads and brake rotors after the above test side by side. You can see that our 2-piece rotor wears less brake pads than the genuine 1-piece type brake rotor . The improvement in the durability of the brake pads under high load is at a level that can be visually recognized. ![](\/\/cdn.atomic-shop.com\/images\/product\/516\/516358\/ER266RC.png)The brake rotor \"Racing\" is painted with \"Thermo Paint\" on the outer circumference of the rotor to check the operating temperature range. Thermo-paint has the property of turning white when the temperature set for each is maintained for a certain period of time, and the color differs depending on the set temperature. __It is painted in two colors, green and pink. Green turns white at about 450 ° C and pink at about 630 ° C for about 10 minutes.__ (* Even if the temperature is slightly lower than the set temperature, it will gradually change if the duration is long, and conversely, if the temperature is significantly higher than the set temperature, the color will change even for a short time.) Semi-metallic brake pads for circuit driving, etc. Bedding (hit at high temperature) is required when using. At that time, if the rotor temperature is not sufficient, brake judder may occur depending on the material. The discoloration of the green thermo paint during bedding is one indication that the bedding was performed at a sufficient temperature, so please check the discoloration of the green thermo paint when bedding. .. If the pink thermo paint discolors, it will be confirmed to run at a very high temperature of 600 ° C or higher. Due to the nature of the material, the cast iron rotor has a usage limit of 650 ° C (as a continuous temperature, not an instantaneous temperature), so please consider increasing the heat capacity by cooling the brake duct, etc., or by increasing the diameter of the rotor.\u003c\/p\u003e","brand":"ENDLESS","offers":[{"title":"Default Title","offer_id":59620428874014,"sku":"ER266RCA","price":4863.05,"currency_code":"AED","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/0553\/3982\/files\/endless-front-brake-rotor-racing-curving-slit_fc9d5dad-3410-4ebc-96e3-0a8dc749f4af.jpg?v=1784119894","url":"https:\/\/atomic-shop.ae\/products\/endless-er266rca-front-brake-rotor-racing-curving-slit-for-toyota-gr-yaris-gxpa16","provider":"ATOMIC-SHOP Performance Parts \u0026 Motorsport Equipment - UAE","version":"1.0","type":"link"}
