Who stated that the area of the pistons in the brake calipers directly relates to the force applied to the brake system?

The correct answer indicates that both technicians acknowledge that the area of the pistons in the brake calipers is directly related to the force applied in the brake system. This relationship is fundamental in understanding how hydraulic braking systems work.

In hydraulic systems, force is transmitted through fluid, and the area of the pistons determines how force is magnified or distributed. This means that larger pistons can exert a greater force onto the brake pads when the brake pedal is pressed, allowing for more effective braking performance. The relationship follows Pascal's law, which states that pressure applied to a confined fluid is transmitted undiminished in all directions throughout the fluid.

Understanding this principle is essential for technicians when diagnosing brake issues, selecting appropriate components, or designing systems to ensure safe and effective braking performance. By recognizing that both technicians share this correct understanding, it reinforces the foundational knowledge necessary for effective work in automotive braking systems.
