9-4 Driving and Operating

Braking

See Brake System Warning Light on

page 5‑21.

Braking action involves perception

time and reaction time. Deciding to

push the brake pedal is perception

time. Actually doing it is

reaction time.

Average reaction time is about

three‐fourths of a second. But that is

only an average. It might be less

with one driver and as long as

two or three seconds or more with

another. Age, physical condition,

alertness, coordination, and

eyesight all play a part. So do

alcohol, drugs, and frustration. But

even in three‐fourths of a second, a

vehicle moving at 100 km/h

(60 mph) travels 20 m (66 ft). That

could be a lot of distance in an

emergency, so keeping enough

space between the vehicle and

others is important.

And, of course, actual stopping

distances vary greatly with 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;

and the amount of brake force

applied.

Avoid needless heavy

braking. Some people drive in

spurts — heavy acceleration

followed by heavy braking — rather

than keeping pace with traffic. This

is a mistake. The brakes might not

have time to cool between hard

stops. The brakes will wear out

much faster with a lot of heavy

braking. Keeping pace with the

traffic and allowing realistic following

distances eliminates a lot of

unnecessary braking. That means

better braking and longer brake life.

If the engine ever stops while the

vehicle is being driven, brake

normally but do not pump the

brakes. If the brakes are pumped,

the pedal could get harder to push

down. If the engine stops, there will

still be some power brake assist but

it will be used when the brake is

applied. Once the power assist is

used up, it can take longer to stop

and the brake pedal will be harder

to push.

Adding non‐dealer accessories can

affect vehicle performance. See

Accessories and Modifications on

page 10‑3.
