What is a consequence of having low brake fluid?

Having low brake fluid significantly compromises the braking system's performance, which is critical for safe vehicle operation. Brake fluid is essential for transferring force from the brake pedal through the hydraulic system to the brakes themselves. When fluid levels are low, it can cause air to enter the braking system, leading to a spongy brake pedal or diminished brake response. In severe cases, it may lead to complete brake failure, putting the driver's safety and that of others on the road at serious risk. Therefore, maintaining the proper level of brake fluid is crucial to ensuring reliable braking performance.
