Maintaining proper brake fluid levels is critical for effective brake performance because the brake fluid is responsible for transmitting force from the brake pedal to the brake components, such as the calipers or wheel cylinders. When the brake fluid is at the correct level, it allows for the proper hydraulic force to be applied, which in turn ensures that the brakes engage consistently and effectively when needed. If the brake fluid is low due to leakage or evaporation, there may not be enough fluid to create the necessary pressure, leading to a spongy brake pedal or even brake failure. Proper brake fluid maintenance also contributes to overall safety by ensuring that the braking system operates as intended, especially in emergency situations where quick stopping is crucial.
