What component connects the piston to the master cylinder and transfers force?

The component that connects the piston to the master cylinder and transfers force is correctly identified as the pushrod. This rod is a crucial part of the hydraulic system, as it transmits the force exerted by the driver's input at the brake pedal through the master cylinder to the piston.

When the brake pedal is pressed, the pushrod moves within the master cylinder, and this motion generates hydraulic pressure that ultimately engages the braking mechanism of the vehicle. Understanding the function of the pushrod is essential for diagnosing issues within the hydraulic braking system, as it plays a vital role in ensuring effective braking performance.

The output rod is not typically recognized in the context of this system, while the input rod and connector rod also do not refer to the standard terminology used to describe the relationship between the piston and the master cylinder in automotive braking systems.
