BRAKE SYSTEM

If power assist is lost for any reason (for example, repeated
brake applications with the engine off), the brakes will still
function. However, you will experience a substantial
increase in braking effort to stop the vehicle.
If either the front or rear hydraulic system loses normal
braking capability, the remaining system will still function
with some loss of overall braking effectiveness. This will be
evident by increased pedal travel during application, greater
pedal force required to slow or stop, and activation of the
"Brake Warning Light" and the "ABS Warning Light" (if
equipped) during brake use.
Hydraulic Brake Assist — 2500/3500 Models Only

(Except Power Wagon)

The brake system power assist is provided by a hydro-boost
unit which shares fluid with the power steering system. You
may experience some clicking or hissing noises from the
hydro-boost system during hard braking conditions.
NOTE:
Under cold temperatures, pedal effort will be higher than
normal until the power steering fluid reaches operating
temperature.
TECHNICAL SPECIFICATIONS

WHEEL AND TIRE TORQUE SPECIFICATIONS

Proper lug nut/bolt torque is very important to ensure that
the wheel is properly mounted to the vehicle. Any time a
wheel has been removed and reinstalled on the vehicle, the
lug nuts/bolts should be torqued using a properly calibrated
torque wrench using a high quality six sided (hex) deep wall
socket.
