BIGGER BRAKES AND BETTER CONTROL.
The added power and hauling capabilities of the even heavier-duty 2011 Silverado HD are
matched by beefed-up brake components and the latest in driver control technology. The front
rotors are signicantly larger* – they are now a full 356 mm (14 in.) diameter. Control is now
enhanced by the StabiliTrak® system and Trailer Sway Control – standard on all 2500HD and
single rear wheel 3500HD models. There’s also an available Integrated Trailer Brake Controller.
Together, these features give you the condence to handle even the heaviest trailer loads –
which is exactly what you get with the new Silverado HD.
HILL START ASSIST
Another way that the new Silverado HD makes
driving your truck easier is with Hill Start Assist.
It holds the truck stationary for about a second
after you release the brake on a ve percent or
greater incline, enabling you to begin to accelerate
before the truck starts to roll backward. Standard
on all single rear wheel models.
INTEGRATED TRAILER BRAKE CONTROLLER
The available in-dash Integrated Trailer Brake
Controller gives you precise control over the trailer’s
braking. The system also works with Hill Start
Assist by holding the trailer’s brakes for about a
second when you are about to accelerate uphill.
STABILITRAK
The StabiliTrak electronic stability control system
enhances vehicle stability and control, particularly
during emergency manoeuvres. It is standard on
all single rear wheel Silverado HD models. This
remarkable safety breakthrough has proven to
reduce the risk of a fatal single-vehicle crash by a
remarkable 63 percent.**
LOCKING REAR DIFFERENTIAL
An industry-exclusive Eaton
® locking rear
differential is standard on Silverado LTZ, required
on Duramax Diesel equipped models and available
on all other models. When one rear tire starts
rotating approximately 100 rpm faster than the
other, the differential locks up automatically.
Both wheels are then driven at the same speed to
help you from getting stuck.
HOW DOES STABILITRAK WORK?
It compares your steering input with the truck’s
actual track, intervening automatically whenever
it detects a loss of lateral traction (sideslip),
understeer (plowing) or oversteer (shtailing).
It helps return the truck to your intended line by
incrementally applying an individual brake and, if
necessary, by reducing engine torque. Proactive
Roll Avoidance is included, reducing the truck’s
tendency to roll over during emergency braking.
TRAILER SWAY CONTROL
StabiliTrak is integrated with the new Trailer
Sway Control which is included on all single
rear wheel models. When the system detects
your trailer beginning to sway, it automatically
intervenes by applying individual brakes and
reducing engine power to help keep your rig
on course.
AUTO GRADE BRAKING
When you are descending a long, steep grade,
Silverado HD’s standard auto grade braking
feature automatically downshifts to help slow
you down, without having to ride the brakes.
BIGGER, STRONGER BRAKES
The new larger rotors and calipers shorten pedal
travel and improve pedal feel. In a panic braking
situation, the Intelligent Brake Assist enables
you to fully apply the brakes more quickly by
pre-loading the calipers.
