The driver would need to step on the brake pedal when braking a vehicle equipped with anti-lock brakes. FYI, the driver would also need to step on the brake pedal when braking a vehicle that is NOT equipped with anti-lock brakes. Hope this helps.
Basically, a brake assist system monitors the driver?s use of the brake pedal, automatically sensing an attempt to stop the car as a result of panic. It then generates very high braking power, even when the driver is only pressing lightly on the brake pedal. When this is used together with anti-lock braking systems, it results in faster and safer braking. Source: http://www.brakeassist.com

There is an electronic relay switch which turns on the rear brake lights-It's located behind the brake pedal- It clicks when you push the pedal down, making contact.
