Finish Line Brake Fluid - DOT 5.1

While generally safe to mix DOT 5.1 fluids from different brands, it is always best practice to use a single brand and type of fluid for optimal performance and to avoid potential compatibility issues.

DOT 5.1 fluid is silicone-based but uses glycol chemistry, making it compatible with DOT 3 and 4. DOT 5 fluid is pure silicone-based and is *not* compatible with glycol-based DOT fluids (3, 4, 5.1). This product is DOT 5.1.

For optimal performance and system longevity, it is recommended to bleed your brakes and replace the fluid annually, or sooner if you notice a degradation in braking performance or if the fluid appears discolored.

This fluid is specifically formulated for bicycle hydraulic disc brake systems. While it meets DOT 3, 4, and 5.1 specifications, using it in automotive systems is not recommended as automotive brake systems have different requirements and operating conditions.

A lower viscosity means the fluid flows more easily, especially at low temperatures. This results in a quicker lever response and better pad retraction, leading to a more immediate and consistent braking feel.

This bottle of Finish Line DOT Brake Fluid contains 4oz (approximately 118ml) of fluid.

This typically indicates air in the system. Bleed the brake system according to the manufacturer's instructions to remove air and ensure proper fluid level.

Ensure the correct DOT 5.1 fluid is used and the system has been properly bled. Check for any potential contamination or wear in the brake pads and rotors.

The fluid has likely absorbed moisture. It is recommended to bleed the system with fresh fluid and dispose of the old fluid properly.

This could be due to internal caliper issues, a sticky piston, or the low viscosity of the fluid not being properly utilized. Ensure the system is clean and free of obstructions. Check the brake manufacturer's recommendations for specific caliper care.
