two acorn nuts. After the air cleaner has been removed it
should be thoroughly washed in gasoline, permitted to drain
and then dipped in fresh engine oil. Do not wash the cover. It
may then be reinstalled by placing it in the top of the silencer
cylinder and replacing the cover.
Brakes
The importance of the proper operation of the brake system as
an essential measure of safety is so great that all service on it
should be performed at a service station where proper adjustments
and tests can be made with the greatest accuracy. Adjustment
should never be neglected so long that the pedal reaches the floor
board before the brakes take effect. In case of emergency, however,
should this occur, the following temporary adjustment can be
made by the driver.
Turn the adjusting nut on the cam lever, shown in figure 31, of
each of the four brakes one half a turn in a clock-wise direction.
These adjusting nuts lock each sixth of a turn to hold the ad-
justment.
A permanent adjustment should be made as soon as a service
station can be reached.
Fig. 3i. A temporary brake adjustment can be secured by turning the adjusting
nut on each brake one-half a turn clockwise.

Tires
The most important factor in the life of a tire is its inflation
pressure. Each tire should be tested at least once a week and the
pressure should be kept at 40 pounds front and rear; if the car is
to be used for high speed driving the pressure of the front tires
should be increased to 45 pounds.
With the inflation pressure properly maintained injuries to the
tire structure will be kept at a minimum. Severe cuts, however,
caused by sharp obstructions in the street or on the road, will in-
variably appear. If these cuts are neglected, the action of the
weather and grit and gravel will in time weaken the tire around
those points. If the cuts are sealed immediately by a good vul-
canizer, however, these points will be protected and the life of
the tire will be lengthened.

The wheels used on the Cadillac V-8 have rims of the drop
center type, constructed as shown in figure 32. The tires supplied
with this type of wheel have a soft rubber tip on the bead to
protect the tube from chafing and a hoop of wire inside the bead
to maintain the shape
of the tire.
The removal and
installation of tires
on the drop center rim
is simple and easy,
because the bead can
be pushed down into
the well on one side
while it is being pulled
over the flange on the
opposite side. Illus-
