Disc Brake Fluid

Bicycle Disc Brake Fluids: Mineral Oils & DOT Fluids

Keeping your bicycle's disc brakes functioning optimally is crucial for safe and enjoyable rides. The two most commonly used brake fluids for bicycle disc brakes are mineral oil and DOT (Department of Transportation) fluid. Both play a pivotal role in the performance of your bike's hydraulic disc brake system. Explore a wide range of high-performance mineral oils and DOT fluids in this category, designed to suit different brake systems.

Mineral Oils

Mineral oils are synthetic oils specifically formulated for hydraulic disc brakes in bicycles. Known for their consistent performance across varying temperatures and conditions, mineral oils offer key benefits:

  • Do not absorb water, maintaining consistent viscosity.
  • Prevent internal corrosion of the brake system.

This category includes various brands and viscosities of mineral oils, each designed to optimize the performance of your bicycle's hydraulic disc brake system.

DOT Fluids

DOT fluids are glycol-based brake fluids that meet stringent Department of Transportation standards. Commonly used in automotive and motorcycle systems, DOT fluids are also suitable for certain bicycle disc brake systems. Key features include:

  • High boiling point to prevent vapor lock and brake fade during prolonged braking.
  • Hygroscopic properties (absorbing water), requiring more frequent fluid changes for optimal performance.

This category includes different grades of DOT fluids, such as DOT 3, DOT 4, and DOT 5.1, tailored to specific performance requirements.

Important Note

Always use the correct type of brake fluid specified by the manufacturer of your bicycle's brake system. Mixing different types of fluids or using the wrong fluid can lead to brake failure and may void your brake system's warranty. Consult your bike's owner’s manual or the manufacturer’s website for the correct specifications before purchasing or replacing brake fluid.
