Braking Braking action involves perception time and reaction time. First, you have to decide push on the brake pedal. to That's perception time. Then you have to bring up your foot and doit. That's reaction time. Average reaction time is about 314 OS a second. But that's only an average. It might be less with one driver and as long as or three secondsor more with two another. Age, physical condition, alertness, coordination and eyesight all play a part. So do alcohol, drugs and frustration. But even in 3/4 of a second, a vehicle moving at 60 mph (100 km/h) travels 66 feet (20 m). That could be lot of distance in an emergency, so a keeping enough space between your vehicle and others is important. And, of course, actual stopping distances vary greatly with the surface the road (whether it's pavement of or gravel); the condition the road (wet, icy); tire of dry, of tread; the condition of your brakes; the weight the vehicle and the amount brake force applied. of Some people drivein Avoid needless heavy braking. spurts heavy acceleration followed heavy by braking -- rather than keeping pace with traffk. This is a mistake. Your brakes may not have time to cool between hard stops.Your brakes will wear out much faster if you do a lot of heavy braking.If you keep pace with the traffic and allow realistic following distances, you will eliminate a lot of unnecessary braking.That means better braking and longer brake life. -- If your engine ever stops while you're driving, brake normally but don't pump your brakes. you do, the If pedal may get harderto push down. If your engine stops, you will still have some power brake assist. But you will use it when you brake. Once the power assist is used up,it may take longer to stop and the brake pedal will be harder push. to

Braking
Braking
action
involves
perception time
and
reaction time.
First, you have
to
decide
to push
on
the
brake
pedal.
That’s
perception time.
Then you
have
to
bring
up
your
foot
and
do
it. That’s
reaction
time.
Average
reaction time
is about
314
OS
a second.
But
that’s
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
3/4
of a second,
a
vehicle
moving at
60
mph
(100
km/h)
travels
66
feet
(20
m).
That
could
be
a
lot
of
distance
in
an
emergency,
so
keeping
enough
space
between
your
vehicle
and
others
is
important.
And,
of
course,
actual
stopping
distances
vary
greatly
with
the
surface
of
the
road
(whether
it’s
pavement
or
gravel);
the
condition
of
the
road
(wet,
dry,
icy); tire
tread;
the
condition
of
your
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
traffk.
This
is a mistake. Your brakes may not
have
time
to
cool
between
hard
stops. Your brakes
will
wear
out
much
faster if
you do a
lot
of
heavy
braking.
If
you keep
pace
with
the
traffic
and
allow
realistic
following
distances,
you
will
eliminate a lot
of
unnecessary
braking. That
means
better
braking
and
longer
brake
life.
If
your
engine ever stops
while
you’re
driving, brake
normally
but
don’t
pump
your
brakes.
If
you
do,
the
pedal
may
get
harder
to
push
down.
If
your
engine
stops,
you
will still have
some
power
brake
assist.
But
you
will
use
it
when
you
brake.
Once
the
power
assist
is
used
up, it may
take
longer
to
stop
and
the
brake
pedal
will
be
harder
to push.
