How does the ABS system work on a GMC?
by Alibaster Smith. The ABS brake system in a GMC vehicle uses a sophisticated ABS module to sense wheel speed. If the vehicle’s wheels stop moving while brake pressure is being applied, but the vehicle itself is still moving, the system identifies this as a skid and automatically releases brake pressure to prevent the brake system from locking up.

If you are experiencing sporadic behavior from your brakes, such as random clicking noises, and/or pumping of the brakes, then the ABS module may need to be replaced.
How does the ABS work on a Ford F150?
The anti-lock breaking system (ABS) on a Ford F150 pulses the brakes for you in the event of hard braking. Rather than manually pumping the brakes, the ABS system pulses the brakes many times faster than any human being could ever do. This prevents the wheels from locking up and keeps the F150 from skidding across the pavement.
