Chrysler' S New Brake
System Improves
Car Control

Outstanding among the many i'm
provementS introduced on the new
1916 ChrySler cars is the ncW-typc
hydraulic brake system offered as
standard equipment on all Chrys-
Ter models.
The new development marks one
OF the most significant advance
mcnts in brake engineering since
Chrysler first gave the automobile
four-wheel hydraulic brakes back
in 1924.
Advantages of the new hraking
system have become quickly ap-
/ parent to owners and drivers of the
! 1916 ChrySlers. Better control of
/ the car is obtained under all driV-
! ing conditions and at the same
time pedal pressure is reduced %
to 80 per cent without sacrificing
/ brake effectiveness. The result is
increased stopping power, both in
ordinary traffic and emergencies,
and sure. smooth control on the
steepest hills.
Some of the higher priced
Chrysler models prior to the war
were equipped with the ncw-typc
brakes. Benefits experienced by
their owners under every kind of
road and weather conditions now
are made available to owners of all
cars in the 1916 Chryslcr line.
Basic to the improved system are
rcdesigned frOnt-whepl brakes that
further apply the brake engineer
ing principle of self-cner2izing.
without sacrificing the Controlla-
biIity and safety which has always
characterized Chrysler brakes. In
stead of Il single hydraulic cylinder
in the front brake drum To acti-
vate both brake shoes. as in con-
ventiOnal systems, an extra cyl
inder has been added To both
Chrysler front wheel brakes an
individual cylinder for each shoI
How this new design delivers It
high degree of controlled brake
action with less foot pedal pres
sure was explained by a Chryslrr
engineer:
When a brake shoe surface is
applied to the drum. the hraking
action is either aided or decreased.
depending on which way the wheel
is rotating. If the direction is away
from the anchor or hinge OF the
brake shoe mechanism, the drum
tends TO throw the shoe away
from its surface. This means part
of the drivers braking effort is
used up simply in holding the
dragging brake shoe against the
drum. Thus. a higher pedal pres
sure is required.
But when the brake drum mo-
ton is toward the anchor. this ac-
ton is reversed. The drum surface
works against the shoe. wcdCing il
closer and setting UP greater brake
actiOn-an action called Sclf-cn-
crgizin%.
I'm the new Chryslcr brakes. six
of the cars eight brake shoes are
self-energiZcd in forward motion
But important To new ChrySler
braking is that controlled sclt-cn-
crgiZing has been Introduced bv
the additional hydraulic cylinders
and proper location of the anchor
on the brake shoe mechanism This
location is important in prevent
ing brakes from becoming Ovcr-en-
ergized to the point whore they
lock"
A simple analogy illustrates the
point. Resting an ordinary push
broom on the floor, pull it towards
you Even if you bear down. the
broom still drags with little re-
sistance. But if you push it. fric-
tiOn and resistance increase with
out any pressure on your part II

rcscnts the brake shoe and whore
you grasp the handle is the anchor
of the brake shoe mechanism. If
you raise the angle of the broom
handle. you reach Il point whore
you Ovcr-cnCrgiZe the broom and il
refuses to move tor lOCkS).
The Introduction of individual
hydraulic cylinders for each shoe
in the Chrysler frOnt-wheel brakes
made possible the readiustment of
brake shoe anchors to insure maxi
mum cOntrOllabilify and prevent
brake jerking and locking.
The result is greater hrakinG cni-
cheney and safety under all condi-
tions with lighter foot pedal pres
sure. For normal traffic stops ~
per cent less pressure is required
than on conventional brake Sys-
tens
Attendant advantages include a
balanced brake action that reduces
Skidding and jerking when brakes
are applied quickly. easier stops and
better car control. longer life for
the brake Innings greater simple
ity of operation. and fewer adjust
ments and repairs. Six fewer parts
are needed in the now ChrYSler
brake system. despite tn" addition
oi the extra hydraulic cylinders.
Resistance to "fadc" or SO-cHllcd
loss of brakes" which results
from heat and distortion caused by
repeated heavy brake applications.
has been fully maintained in the
new Chryslcr brakinG system.
along with its other advantages.
