In which step does the pressure transmitted to the caliper occur during brake operation?

The pressure transmitted to the caliper occurs when hydraulic pressure is applied to the brake system after the driver presses the brake pedal. This process typically starts in the initial step where the brake pedal is engaged. During this initial step, the force exerted by pressing the pedal is transferred to the master cylinder, generating hydraulic pressure. As this pressure builds, it is sent through the brake lines to the caliper.

In this context, when identifying the specific step where pressure transmission to the caliper occurs, the first step is crucial because it lays the groundwork for the subsequent actions of the braking process. This first step is essential for understanding how hydraulic systems work in vehicles, ensuring that the energy exerted by the driver is effectively transmitted to the braking mechanism, ultimately facilitating the deceleration of the vehicle.
