Brake fluid plays a pivotal role in automotive braking systems as a hydraulic medium. Through the principle of Pascal's law, it efficiently conveys the mechanical force applied to the brake pedal to the brake calipers or wheel cylinders, facilitating precise deceleration and ensuring vehicular stopping safety. Commonly available brake fluid standards include DOT 3, DOT 4, and DOT 5, each formulated with distinct chemical compositions and performance characteristics tailored to specific operating conditions and vehicle requirements.
Over time, brake fluid can absorb water, reducing its boiling point and leading to potential brake failure. Regular checks and timely replacement are essential. If the fluid looks dark or the brake pedal feels spongy, it's time for a change.
