Answer :
Final answer:
The emergency brake does not engage when the brake pedal is pressed because it is a separate system from the hydraulic brake. The emergency brake must be engaged manually using a different mechanism.
Explanation:
The emergency brake does not engage when the brake pedal is pressed because the emergency brake is a separate system from the hydraulic brake that is activated by the brake pedal. The emergency brake, also known as the parking brake, is a mechanical brake that is connected to the rear wheels of the vehicle and is independent of the hydraulic brake system. When the brake pedal is pressed, it activates the hydraulic brakes, which use Pascal's principle to increase the force applied to the brake pads or shoes. However, the emergency brake must be engaged manually using a separate lever or pedal.
