A mechanic in Nairobi explains that when a driver presses the brake pedal, all four wheels slow down simultaneously. Which principle explains how the braking force is transmitted equally to each wheel?Diagram: Imagine a labelled diagram showing: brake pedal connected to master cylinder, fluid lines branching to four wheel cylinders. All wheel cylinders have the same amount of brake fluid pressure.
