What type of brakes do all fire apparatus manufactured after 1990 utilize?

Answer: C — Anti-locking brakes

Fire apparatus manufactured after 1990 are equipped with anti-locking brakes (ABS) as a standard safety feature. The purpose of anti-lock braking systems is to prevent the wheels from locking during hard braking, which can lead to loss of control of the vehicle. This is especially critical for fire apparatus that may operate in emergency situations requiring sudden stops or quick maneuvers. ABS enhances the overall safety of the vehicle, allowing for better steering control during braking and reducing the risk of skidding. While drum brakes, disc brakes, and hydraulic brakes may all be found on various types of vehicles, including fire apparatus, they are not uniformly utilized in all fire equipment manufactured after 1990. Anti-lock braking systems became more prevalent in this timeframe to comply with safety regulations and improve vehicle handling in emergency response scenarios.
