Dr. P. -C. i Stanley, chief ;. engln

f asbestos ' brake lining. in; the
vorldjn writing on the subject of
rakea and braking for tbe Na
lonSl Safety News, says:'1,-:
"The efficiency of automobile
) rakes depends upon (1)' the
pressure applied to, the pedal; , ( 2i
he ngechanlcab advantage c of the
ippllqation;: (3) the diameter of
:he brake drum; (4) the coeffi
cient of friction of the lining; and
(6) tfie adjustment of the brakes;
"Fdur jwheel brakes, ,wheu ful
y efficient,, will cat doWnstop
plng distances" full jr 5 0 ' per ceht;
tut . four wheel brakes, . like, all
other! ' are often far below their
aximum. in efficiency. Taking
p iistMeir order the factors in
rake efficiency mentioned, the
oUowtngcdrnment will be suffi-
jciently explanatory: ,
t "(1) The pressure which can
be applied to the brake pedal var-
Jes with the weight and. strength
kf the driver; but no - person
should drive a car on which he is
unable to lock both rear wheels by
pressure on the pedal in emer
gency. ....
"(2) The mechanical advan
tage of the application may . be
measured by the ratio of the ped
al travel to the average Clearance
between brake lining and 'drum.
In some cases this is as high as
120.1 which means that one
pound of pressure on the pedal
will in theory apply aa s average
pressure of 120 pounds , between
the lining and the druffi This
high efficiency is diminished, of
course, by friction, which Isv gen
erally increased greatly by. lack
of lubrication and by rusting,, ,
. "(3) The larger the diameter
of the brake drum, the more ef
fective is the pressure applied to
it. Drum diameters are --limited
by wheel sizes, and these are gen
erally reduced by the general use
of balloon tires.
"(4) The coefficient of fric
tion of the Brake lining when dry
and free from oil is .4 to .6, which
means that from .4 to .0 of.-the
pressure applied to it will" be ef
fective, in retarding the. rotation
of the brake drum. The efficien
cy of the lining is greatly reduced
by a film of reasei oil or, water.
The water film may be destroyed
by applying the brakes, but an
oil or frrease film is , found -. al
most Impossible, to com pleteljr re
move. -
" ( 5 ) The normal efficiency of
pavement Is but , under some
conditions fails as low as .5; ,We
must realize that all braking ef
ficiency depends on the friction
between the tire and pavement,
and therefore we will .' reduce
speed when the character ef the
pavement Is unknown.,
"(6) By braking adjustment,
we mean particularly the setting
of the bands or shoes to an even
and proper clearance between lin
ing and drum. This clearance in
creases as the Untax wears, and
need for adjustment Is discovered
by the fact that the pedal must
be pushed to the floor board to
obtain efficient braking. All ad
justments should benade on the
adjustment screws on the brakes.
never on the pull rods. Shorten
ing pull rods decreases mechani
cal advantage.
'The one test of brake effi
ciency which every driver can
make has already been pointed
out. This Is the ability quickly to
lock both rear wheels by pushing
on the pedal: If unable to d so
when braking an. emergency stop.
Ha brakes need attention. . I do
not advocate locking wheels in
this manner as a regular practice,
hut it reoresents maximum effi
ciency.
"Whim brakes are unequal In
efficiency, they become less ef
fective and more dangerous. They
Increase the tendency Jte said.
Eoualiiation is usually tested by
comparing the lengths of marks
made on the pavement py locaea

Owner records of performance
which arc coming In to the various
ranches of Willis-Overland.lifhfc'..'
indicate that the new Willys
Knight "70" is revealing rather
unusual speed ability in all sec
tions ol the country, according to
a. statement given out by the: local
representative after a talfejjwith
one of the travelling engineers
ed ; with' marked frequency.
Oviiers report that it is quite
th ordinary thing to average 40
miles an hour over trips up to
400 tff 450 miles in a day which
means I that much driving is done
.well over the sixty mile an hour
mark. ;
In; this respect, the American
built, Willys-Knight is the coun
terpart of the European: Knight:
motored cars which have set and
heJd many of the most, important
Continental speed records : f or
stock' cars.- ; ', V;.".
According to? the local repre
sentative, the construction of the
Knight sleeve valve motor adapts
itself particularly w ill ' lor high
speed performaoice.
"The action of the sleeves in
itself is proof; against .'the usual
feeling . of' . ssvero motor ' strain
under long, sustained high speed,"
he says. "Many drivers do not feel
that they want to keep the motor
of their car "? turning over at a
high rate of speed because they
do not like
gine. The Wilys-Knight " owner
never has this feeling, for at high
speeds as well as at moderate
speeds the power plant operates
with convincing smoothness and
silence.. ..u't'' -V'
