In what order do the components of the braking process move during application?

During the braking process, the components operate in a systematic order that ensures effective braking. When the brake pedal is pressed, it initiates the application of the brakes. This is the first step where the driver exerts force on the brake pedal.

The movement from the brake pedal to the master cylinder follows naturally, as the master cylinder is a hydraulic device that converts the force from the brake pedal into hydraulic pressure. This pressure is then transmitted through the brake lines to the various braking components.

Finally, the hydraulic pressure produced by the master cylinder reaches the wheel cylinders (in drum brake systems) or the calipers (in disc brake systems). In this last step, the hydraulic pressure causes the brake shoes or pads to engage with the brake drum or rotor, respectively, resulting in deceleration.

Thus, the correct sequence of operation is: brake pedal, master cylinder, and then the components at the wheels (either wheel cylinders or calipers), which aligns perfectly with the answer provided.
