What would be the expected result of an inoperative ABS pump/motor assembly?

An inoperative ABS (Anti-lock Braking System) pump/motor assembly affects the ABS system's ability to prevent wheel lockup during hard braking, but it does not eliminate the vehicle's ability to brake altogether. In scenarios where the ABS is not functioning, the conventional hydraulic braking system remains operational.

This means the driver can still apply the brakes and bring the vehicle to a stop, albeit without the added benefits of ABS, such as enhanced control in slippery conditions. Without ABS, the driver must be more cautious to avoid locking up the wheels, especially during emergency stops. However, the primary braking system will still engage effectively, allowing the vehicle to retain braking capabilities.

Other choices suggest harsher consequences that do not align with the behaviors of a traditional braking system. For example, the idea that the vehicle loses all braking power is incorrect, as the conventional brakes operate independently of the ABS. The proposal that warning lights disable vehicle performance is misleading, as lights may indicate issues without directly affecting the function of the brakes. Lastly, the notion that braking force would be significantly increased contradicts the fact that, while brakes still work conventionally, the potential for wheel slip and loss of control can increase without the ABS intervention.
