brake fluid

Too Afraid to Ask

Brake fluid is the liquid that helps your bike's brakes work. If it’s low or dirty, the brakes won’t stop as well, so you need to check and top it off regularly.

Technical Definition

Brake fluid is a hydraulic fluid that transmits pressure from the brake pedal to the calipers or wheel cylinders, allowing the brakes to function. It must be kept clean and at the correct level to ensure safe stopping power.
