cables apply an equal pull to each
brake shoe lever, and the levers
and struts force all rear brake
shoes into firm contact with the
brake drums. A spring-loaded
latch automatically l o c k s the
brake lever to keep the parking
brakes applied. The brake lever
is released by pushing down
(49000), pulling (45, 46, 48) on the
release knob. A warning signal,
which is standard on 48, 49000
Series and optional on Series 45,

instrument panel if the car is
operated with the parking brakes
applied.
c. Service Brake Control
System—Standard Brakes
NOTE: See Sections 9-D and 9-E
for power brakes.
The regular foot-powered service
brake control system is a pedal
operated hydraulic system which
applies the brakes at all four
wheels with equalizer pressure.
The hydraulic system consists of
one master cylinder connected by
pipes and flexible hoses to a
wheel cylinder mounted between
the brake shoes at each wheel.
The m a s t e r cylinder, pipes,
hoses and four wheel cylinders
are filled with brake fluid. The
stop light switch is mounted on
a bracket just rearward of the
brake pedal shank. With the
brakes fully released, the switch
plunger is fully depressed against
an operating plate on the pedal
shank. See Figures 9-7 and 9-8.
A coiled brake pipe extends down-
ward from the master cylinder to
a distributor located on the left
frame rail. A brake pipe extends
rearward from the distributor to
a hose located inside the left
frame rail, on 49000 Series, and
located near center of spring
cross member on the 45-46-48000
Series. This hose is connected to
a tee located on the axle housing.
Two pipes lead off from the tee,
one to the left rear wheel cylinder
and the other to the right rear
wheel cylinder. See Figures 9-5
and 9-6.
The brake pedal is suspended
from a pivot shaft in the pedal
bracket. The master cylinder
