Final answer:
Brake fluid is a hydraulic fluid that pressurizes the braking system, allowing for the vehicle's service brake to work.
Step-by-step explanation:
Brake fluid is a hydraulic fluid used in the braking system of vehicles. It pressurizes the braking system, allowing the vehicle's service brake to function properly.
Hydraulic brakes operate based on Pascal's principle. When the driver pushes the brake pedal, the force is increased by a simple lever and then by the hydraulic system. This pressure is transmitted undiminished to all parts of the hydraulic system, including the wheel cylinders.
Therefore, the statement is true, as brake fluid does indeed pressurize the braking system and allows for the vehicle's service brake to work.
