Ford Ecosport: Anti-Lock Brake System (ABS) and Stability Control / Description and Operation - Anti-Lock Brake System (ABS) - Overview
Overview
The ABS system is comprised of the following subsystems which assist
the driver in maintaining control of the vehicle during braking:
The ABS helps maintain steering control by preventing the wheels
from locking up during hard braking. The ABS also includes a brake
assist function to provide maximum brake system pressure during a severe
braking event.
The EBD system helps maintain vehicle control by keeping a balanced braking condition between the front and rear wheels.
Some noise from the system and pulsations in the brake pedal are
normal conditions during most ABS events. Longer than normal brake pedal
travel may also be experienced immediately following an ABS activation.

If the seatbelt webbing does not extract from the seatbelt
retractor from the stowed position, this may be due to a normal
condition which happens when the seatbelt retracts at a high rate of
speed. Follow these steps to release the seatbelt.
