Dodge 2013 Challenger - Manual (Page 336)

In the event power assist is lost for any reason (for
example, repeated brake applications with the engine
OFF) the brakes will still function. The effort required to
brake the vehicle will be much greater than that required
with the power system operating.
Anti-Lock Brake System (ABS)
The Anti-Lock Brake System (ABS) provides increased
vehicle stability and brake performance under most
braking conditions. The system automatically “pumps”
the brakes during severe braking conditions to prevent
wheel lock-up.
The Electronic Brake Force Distribution (EBD) prevents
the rear wheels from over-braking and provides greater
control of available braking forces applied to the rear axle.
When the vehicle is driven over 7 mph (11 km/h), you may
also hear a slight clicking sound as well as some related
motor noises. These noises are the system performing its
self check cycle to ensure that the ABS system is working
properly. This self check occurs each time the vehicle is
started and accelerated past 7 mph (11 km/h).
ABS is activated during braking under certain road or
stopping conditions. ABS-inducing conditions can in-
clude ice, snow, gravel, bumps, railroad tracks, loose
debris, or panic stops.
You also may experience the following when the brake
system goes into anti-lock:
• The ABS motor running (it may continue to run for a
short time after the stop),
• The clicking sound of solenoid valves,
• Brake pedal pulsations, and
• A slight drop or fall away of the brake pedal at the end
of the stop.
These are all normal characteristics of ABS.
