Coated Brake Rotors: What You Need to Know
Brake rotors play a critical role in ensuring the safety and performance of your vehicle. They must be durable and resistant to rust to maintain their function. Coated brake rotors are a common solution to this issue. In this article, we will explore what coated brake rotors are, how they work, and whether you need to clean them before installation.
What Are Coated Brake Rotors?
Coated brake rotors are specifically designed to resist rust and prevent corrosion. These coatings can be applied in a variety of ways, including:
Grease coatings for protection during transportation and storage. Non-ferrous materials to prevent unsightly rust on areas not worn away by brake pads. High-temperature paint around the rotors to prevent rust.The main goal of these coatings is to protect the rotor surfaces from rust and maintain their performance over time.
Understanding Factory Coatings
Most brake rotors come from the manufacturer with a protective coating to guard against rust during transit and storage. This coating is typically a low-viscosity grease designed to prevent rust formation. To ensure the best results after installation, you should clean the coating off using a brake cleaner aerosol before fitting the rotor to your vehicle.
It’s important to note that the cleaning process is straightforward and can be done with a can of brake cleaner. Simply spray the cleaner onto the rotor and allow it to evaporate. This will remove any protective coating and ensure that your new rotors are free to perform their intended function.
Benefits of Coated Brake Rotors
Coated brake rotors offer several advantages, including:
Enhanced durability: The coating helps to prevent premature rusting and prolong the life of the rotors. Aesthetics: The coated areas, particularly on the hub, can help maintain a shiny appearance. Resistance to rust: The coating resists rust, making the rotors look and perform better for a longer time. Cost: Coated rotors often cost more due to the extra manufacturing steps, but they can save you money in the long run by reducing the need for replacement.One downside to keep in mind is that if you drive in areas where salt is heavily used on roads or live near the coast, the protective layer might be compromised. In such cases, the rotors may still rust over time despite the coating. However, in most other conditions, coated brake rotors are a reliable solution.
Conclusion
Coated brake rotors are an effective means of protecting your vehicle’s braking system from rust and corrosion. Whether you need to replace your rotors or are just curious about their benefits, the coating can help ensure your brakes remain in excellent condition. By understanding the types of coatings available, the importance of cleaning, and the benefits and limitations, you can make informed decisions about your vehicle’s maintenance.
