BRAKE PEDAL - PAGE 17-10
Add the following note: After May 31, 1949 there
was released for production a new brake pedal rod
which is 1/4" shorter than the pedal rods used on
previous production for the 480-490 Series.
To adapt the J-2795 Brake and Clutch Pedal
Remover for the shortened pedal rods it will be
necessary to add a horseshoe washer 1/4" thick with
a slot milled in the washer. The opening in the
washer must be large enough to enter over remover
adapter; for specifications see Figure 2.
FIGURE 2
PEDAL PUSH ROD ADJUSTMENT - PAGE 17-10
With the brake pedal free-play between 1/4" - 3/8"
there must be a clearance of 1-1/4" between the rear
side of retaining pin (3) and end of slide link (2),
Figure 1.
This adjustment is important in order to obtain the
proper mechanical follow-up to the hydraulic opera-
tion of the rear brakes. The safety factor of having
mechanical brakes following the hydraulic brake
action is lost unless this adjustment is checked on
every car, whenever brake work or inspection is
done.
MAJOR BRAKE ADJUSTMENT - PAGE 17-13
Refer to paragraphs 14, 15, 16 and 17, also note
references and make the following changes: The
.015" feeler gauge and clearance dimension is in
error. This should be .020". Also add; Insert the
.020" feeler gauge between center of secondary shoe
lining and brake drum and turn adjusting screw until
feeler gauge is gripped lightly. After removing the
feeler gauge, the retraction springs will automati-
cally adjust both shoes to the recommended .010"
clearance between the lining and drum all around.

WHEELS AND TIRES
TIRE INFLATION - PAGE 19-4
Paragraph 5 should read: Keep tires inflated to
the following pressure:
Size Front Rear
7.10 x 15 - - 26 pounds cold - 24 pounds cold
7.60 x 15 - - 26 pounds cold - 24 pounds cold
Normal city driving will cause a pressure build-
up of at least three pounds above the "cold" pres-
sure, while highway driving will cause a pressure
build-up of at least five pounds above "cold" pres-
sure. Use these pressure build-up values only as a
guide when it is necessary to check tire pressures
(hot). Never reduce (bleed) build-up pressure in a
tire. The tire is designed to protect itself by building
up a safe pressure of a few pounds after it is run.
This avoids excessive side- w all flexing and heat--
both of which are detrimental to a tire.
Ordinarily tire pressure should be checked at
least once a week. However, when touring, or if the
car is driven extensively, they should be checked
every morning before starting out.
Tire valve caps should be finger tight to prevent
loss of air due to a leaky valve and to prevent dirt
getting into the valve. Replace missing valve caps
promptly.
