| 8. What types of brakes are In
present use on automobiles7
Automobile brakes for rear wheels
are divided into thre general classes;
internal expanding band. internal
expanding shoe and external con-
tracing band. When brakes are APP
piled, the first mentioned brake band
OF some thin metal expands against
the inside OF brake drum; the
| second has, heavier shoes" which
| are operated by. a cam, expanding
against the drum; the third brake is
drum with a thin band contracting
against 1T on the outside. Both bands
and shoe have a. friction lining OF
some asbestos composition which is
more heat and wearo resistiag than
metal, altho some brakes OF the
expanding shoe type are made with
no inning. Another type known az the
transmission brake is located on the
main driving. shaft near the trans
mission. Il is similarly constructed
and usually used for emergency, OPP
Grating by hand lever.
4. How can a radiator be painted
easily and quickly without the use
Of brush7
The easiest way to apply paint to
o radiator without brush Is to
purchase or make a spraying outfit,
insuring q better Job with less
trouble. The outfit consists Of a can.
such as gallon gasolene can. an
air pump and hose attached to the
pump and passing thru the can near
the top. Another tube extends from
the air hose down into the liuuid
within the can, and is placed with
Its upper end outside the can and
close to the mouth Of the air tube.
Thus, when the pump handle is
worked up and down the LIQUID Il
drawn to the mouth OF the air hose,
ana IL forced In al spray from the
hose under pressure OF air from the
pump.
Q. What IL the cause Of vibration
IN sreedometer pointersi
The cause OF vibration IN speed
ometer Indicators may be loose un-
ions at either end OF tho driving
smart, fibre gears not meshine prop
eriy, too sharp q bend In the shaft or
lack OF lubricant. The latter IL the
chfef cause Of noise in the speed
ometer drive. When the speedometer
does not indicate look for loose con-
| nection. broken shaft links, stripped
gears or gears not engaged,
.. What are two methods for
timing OF valves, should the present
timing be incorrect, or Oh reassenb
ling a motor!
TO time the valves. one method is
to mesh the timing gears. with the
marked tooth Of one gear exactly In
ilne with that Of the correspondents
tooth OF the gear it engages. Anoth-
or way Is by using the ny wheel
which should be marked for top
dead center Of each piston's stroke
also the position when each valye
opens and closes. AS an example: on
four cylinder engine, the inlet
valve opens at five degrees past TOP
center. and closes at forty degrees
past bottom center. The exhaust
valve opens at FORTY desraas h.eor.
bottom center and closes at seven
degrees past top center.
I. What Is the firing order Of
multiple cylinder engines, Is it DOS
sibl6 for cylinders to fire IN consecu-
tive order. as they are numbered
from front to rear Of the enrine!
The firing order Of four cylinder
is either one three. four, two or one
two. four three. 1t is possible to
make an engine fire In consecutive
order, one, two. three, four by CON-
