Hydraulic disc brake systems have become the most common type of braking system in modern bicycles and motorcycles. Thanks to their excellent braking performance and precise control, they are widely favored. Brake fluid (hydraulic fluid) is a critical component in a hydraulic disc brake system. Choosing the right brake fluid ensures the stability and long lifespan of your braking system. In this post, we will guide you through how to choose the best hydraulic disc brake fluid and introduce Star Union's high-performance brake fluid.
1. Types of Hydraulic Disc Brake Fluids
Hydraulic disc brake fluids primarily fall into two categories: mineral oil and synthetic (DOT) fluid. Choosing the right brake fluid not only enhances braking performance but also prevents damage to the braking system.
Mineral Oil: Mineral oil brake fluids are popular for their lower corrosiveness, which protects metal parts better and is relatively inexpensive. Brands like Shimano and Magura use mineral oil in their brake systems. While mineral oil works well for general use, it has a narrower temperature range and is not suitable for extreme riding conditions.
Synthetic Oil (DOT Fluid): Synthetic fluids offer better high-temperature resistance and corrosion protection, making them ideal for more demanding riding environments, especially high-speed cycling or extreme weather conditions. Common brands like Avid and Hayes use synthetic oils. While these fluids provide superior performance, they tend to be more corrosive and require extra care when handling.
2. Key Factors to Consider When Choosing Brake Fluid
Compatibility: Different brands and models of hydraulic disc brakes require different types of brake fluid. Using the wrong fluid can cause brake failure or system damage. Always choose brake fluid that is compatible with your bike or motorcycle's brand and model.
Temperature Range: For high-intensity cycling, synthetic fluids perform better due to their high-temperature resistance. Mineral oils are better suited for lighter, everyday use.
Sealing and Corrosiveness: Brake fluid’s sealing ability prevents moisture and air from entering the system, while its corrosiveness affects the longevity of the brake components. Choosing the right fluid helps mitigate these risks and ensures a longer-lasting brake system.
Brand Choice: Reliable brands provide superior protection and performance for your brake system. Star Union, a reputable brake fluid brand, offers high-quality, stable brake fluids that meet a wide range of cycling needs.

4. How to Change Hydraulic Disc Brake Fluid?
Regular brake fluid replacement is vital for maintaining the proper functioning of your hydraulic disc brakes. The general recommendation is to change your brake fluid once a year or when you notice a decline in braking performance. Here are some tips for changing your brake fluid:
· Choose brake fluid that matches the manufacturer's specifications.
· Perform the replacement in a clean environment to avoid contaminants entering the brake system.
· Ensure all air bubbles are removed during the fluid change process.
· Follow the instructions provided in the user manual or have a professional mechanic handle the replacement.
