If brake pedal pressure is lost, what could this indicate?

When brake pedal pressure is lost, it primarily indicates issues related to the hydraulic system that operates the brakes. One of the most common reasons for a loss of brake pedal pressure is low brake fluid. The brake fluid is crucial because it transmits the force from the brake pedal through the hydraulic lines to the brake components. If the fluid level is low, there may not be enough pressure generated when the pedal is pressed, resulting in a soft or completely unresponsive brake pedal.

Low brake fluid can be caused by a leak in the brake lines, seals, or cylinders, or it could be due to the natural consumption of fluid as brake pads wear down over time. Thus, diagnosing low brake fluid and checking levels should be a priority when brake performance is compromised.
