Braking - Chevrolet 4500 HD 2023 Manual

Engine
Check that engine coolant is not
leaking from the radiator and other
parts of the cooling system.
Check that the engine coolant level is
high enough.
Check that the fan belt is properly
tensioned and free of damage.
Check that the engine oil level is
correct.
Fuel tank
Check that the fuel level is high
enough.
Diesel Exhaust Fluid (DEF) tank
Check that the DEF level is high
enough.
Highway Driving Guidelines
Speeds on highways are higher than
those on regular roads, so there is more
danger. Also, a breakdown on a highway
represents a hazard to other vehicles and
can cause an accident. Concentrate on
safe driving. Remember to perform daily
pre-operation inspections and use
highway driving techniques.
Refer to Owner Checks and Services 0 322.
When merging with traffic on a highway,
use the turn signal lights to indicate your
intentions ahead of time. Speed up
sufficiently when you are in the
acceleration lane. Pay attention to
vehicles behind you and to conditions in
the lane you are joining. Merge in such a
way that you do not obstruct vehicles in
the lane.
Your sense of how fast you are traveling
becomes distorted on long highway
drives. Constantly keep an eye on the
speedometer, and maintain a suitable
headway distance.
During high-speed driving, even a little
turn of the steering wheel causes a big
movement of the vehicle. Turn the
steering wheel slowly.
Excessive use of the brake pedal is
extremely dangerous because it rapidly
wears the brake linings and causes brake
fade. Make effective use of engine
braking and the exhaust brake when you
want to decelerate.
When you want to turn off a highway,
use the turn signal lights to indicate your
intentions ahead of time. Paying
attention to vehicles behind you, turn off
the highway smoothly so as not to
obstruct other vehicles.
Driving and Operating
Brake Fade : Frequent use of the brakes can
cause the brakes to overheat so that the
frictional force of the brake linings decreases
and the brakes become less effective than
normal. This phenomenon is called
brake fade.

Braking

Brake Operation
The brakes give strong braking force with
only light pressure on the pedal. Do not
press the brake pedal hard except in the
event of an emergency.
Actual stopping distances vary greatly. Your
ability to stop safely will be greatly affected
by the surface of the road, whether it is
pavement or gravel; the condition of the
road, whether it is wet, dry or icy; tire
tread; the condition of the brakes; the
weight of the vehicle; the weight of the
load; and the amount of brake force applied.
Please allow for realistic stopping distances
to avoid unnecessary heavy braking. That
means better braking, longer brake life and
safer driving.
