What is the acceptable range for a vehicle's brake fluid level?

The acceptable range for a vehicle's brake fluid level is defined by the markings on the reservoir, specifically between the minimum and maximum levels. This range is crucial for ensuring the proper operation of the braking system. If the fluid level is below the minimum marking, it can lead to insufficient hydraulic pressure, affecting braking performance and potentially causing brake failure. Conversely, if the fluid exceeds the maximum level, it could overflow and create a mess, or more critically, cause the braking system to malfunction. Maintaining brake fluid within this designated range ensures that the brake system remains effective and safe.
