Case And Point: Seeing The Light

摘要

When there's a failure in a vehicle's antilock braking system (ABS),the ABS computer is programmed to illuminate the amber "antilock" warning light and allow conventional braking.But how do failures in the foundation braking system affect operation of the ABS? In every case we can think of (with all the variations out there,there may be a rare exception),any foundation-brake failure that would cause the red "brake" warning lamp to glow also will illuminate the ABS telltale and cause the ABS to quit modulating brake-fluid pressure to the individual brakes.But if the failure in the basic braking system isn't too severe,the car may still be able to stop.
