The brakes on modern cars have come a long way since the early engines of the past. As cars continue to improve their brakes, car manufacturers like Renault have begun to explore new technologies to make them even better. Brake rotors, specifically, have begun to be treated with special coatings that help them last longer and improve their performance. Specifically, Renault has introduced a variety of brake rotor surface treatments designed to make their brakes last longer and perform better in some of the most extreme conditions.
One of the most common treatments applied to Renault brake rotors is an anodized coating. This coating is applied to the rotor and acts as an insulation barrier between the rotor and the brake pad. This barrier helps to reduce brake fade and warping, making the rotor last longer and increase performance in extreme conditions.
Another common treatment applied to brake rotor surfaces is nitriding. This process helps to increase the hardness and strength of the rotor, making it less likely to fail in extreme conditions. Unlike anodized coatings, this process helps to provide improved noise reduction and also helps reduce brake dust.
A third method of improving brake rotor performance and life time is shot peening. This is a process wherein small particles of iron are shot at the rotor surface in order to drive out imperfections that could reduce the rotor’s efficiency. This helps to increase the rotor’s lifetime and reduce the chances of brake fade.
Lastly, Renault also applies a special coating to their brake rotors called the Diamond Coating. This coating increases the abrasion resistance of the rotor, making it more resistant to wear. It also helps protect the rotor from corrosion and improves its appearance.
Overall, Renault has made great strides in improving the performance and life cycle of their brake rotors. Their variety of surface treatments have helped to reduce brake fade and make their brakes more efficient in extreme environments. The anodized coatings, nitride treatments, shot peening and diamond coatings have all gone a long way in increasing performance and protecting these rotors from the most extreme conditions.
