so 1t is rather discriminating to have
witness mention the tire noise
when testifying in court following
an accident Tire noise, further
more, should be tip to the driver
himself. 1t should Immediately tell
him that he has made the mistake
Of transferring braking from the
brake drums to the tire treads-a
plan that never produces a safe or
satisfactory stop. At the first sign
of tire squeal the brakes should be
released and then Immediately ap-
piled again. This usually resolves
itself into "dabbing" the brake ped
al. Call it applying full braking
power in installments, If that makes
the idea clearer.
1t Needs Some Slack.
Having learned that it is risky
to have spongy pedal where the
brakes are of the hydraulic type,
many drivers have worried them
selves into thinking that any slack
in the pedal also indicates need for
service. AS matter of fact, it is
essential that the pedal 60 down
a short distance before there is any
resistance to its movement. Unless
this slack is provided, the compep-
satlng port in the master cylinder
will not operate properly and the
entire system will become upset.
Cutting Out Second.
Now that We are trying to SIM
plify the business OF driving by
putting the shift lever on the steer
ing column, it should be apropos to
suggest the idea of going direct
from low to high when the car is
not starting off uphill and when it
is not heavily loaded. Run to about
IL miles per hour in low and go
directly to high. Any modern engine
can pick up from that speed with
ease. This will result in a very
definite saving in wear on the
transmission, clutch and shift con-
troll 1t will also save gas. because
tests show that most drivers run
faster in second gear than is nee
essary. Use second for fast maneu.
vering in traffic or on steep up
grades where the engine would labor
in high.
Motorists Want to Know.
@. Why is it advisable to use new
fluid when bleeding the lines of
car with hydraulic brakes? 1t seems
to me that, since fluid is used in
a closed system, there should be no
harm in using it over again. r. w.
A. The purpose in bleeding lines
is to remove air Thus the old
fluid is likely to have air bubbles
which would be put back into the
system if the old fluid were used
again. Also there is some possibility
of dirt getting into the old fluid.
@. 1 am troubled by having the
engine of my car die when I try to
accelerate on a hill Have you any
idea what may be wrong? F. L. L.
A. If the mixture is too lean there
should be a popping sound "a real
backfire) from the carburetor when
the engine fails to accelerate. If
there is no such noise, then the mix
ture probably is much too rich.
There may also be something wrong
with the acceleration pump,
@. Am planning to install two
new tires on my car and should
like your advice regarding the prop
er wheels on which to put them. I
read recently the advice of tire
maker, who says the newest tires
should be put on the right front
and right rear wheels. as these are
the points of greatest wear
w. A. j.
A. You also may have read that
it is dangerous to put all the new
traction on one side OF the car,
since this may throw the car into
skid in case of quick stop. I
think it is safer and more sensible
to put the new tires on the rear.
leaving the next two best tires on
the front. If the rear tires are not
badly worn put them on front, be-
cause their treads will be free of
"cupped' spots and the car will run
more quietly.
