At what pressure do ABS brakes governor cut out?

The correct answer regarding the pressure at which the ABS brakes governor cut out is 130 psi. This specific threshold is important to understand in the context of vehicle braking systems. When the air pressure in the brake system reaches 130 psi, the governor activates to ensure that the air compressor stops filling the air tanks, preventing over-pressurization which could lead to potential system failures or malfunctions.

Understanding this pressure cut out is essential for driver/operators, as it plays a critical role in the overall functioning of the braking system, particularly in maintaining optimal pressure for safety and efficiency. Knowing the operational parameters of ABS and the function of the governor helps in diagnosing possible issues that could arise during vehicle operation, ensuring that the braking system remains efficient and functional.

This knowledge helps reinforce good practices in preventive maintenance and helps operators recognize when their vehicles may be operating outside of safe prescribed pressure limits.
