DEALER IS ADVISED

Moon has adopted four.wheel ny
draulic brakes. That is the interesting
announcement made this week by the
engineering department of the Moon
Motor Car company, who up to this
time have not made known its posi-
ton in the matter of quadruple brak-
ing systems, according to the Embleton
Motor company, distributors here.
every approved European and
American system of four-wheel brakes
has been carefully considered and thor
Oughly tested by u.s." says George II.
Kublin, chief engineer of the Moon
Motor Car company, land we have
adopted the Lockheed type of hydrau-
lie four-wheel bra kes because we found
1t more practical and efficient than
any other system, and being of simple
construction, requires practically no
adjustment. Another point in their
favor is that they require no lubrica-
ton, whereas mechanical brakes re-
quire regular fabrication at over 80
points on the chassis, many of these
points being difficult to reach.
Why They. Are Selected.
Kublin gives the following informa-
ton concerning hydraulic lfour-wheel
brakes of the Lockheed type, adopted
by Moon, which influenced them in
favor of the hydraulic brakes es OPP
posed to all other types of four.wheel
brakes. He states:
Through the hydraulic principle,
the brakes are eQualized perfectly and
automatically on all four wheels at all
times. -......
The same braking pressure is. APP
piled to each wheel and released in
stantly when the brake pedal is re-
leased.
The brakes interfere in no way
with easy steering in the slightest de-
gree, even on sharp turns. -
.Chances of skidding under any con-
ditions are greatly 1essened. -
Friction Is Eliminated.
Practically all friction is elimin-
ated, whereas in mechanical brakes
about 20 per cent of the power, applied
on the foot pedal, is lost because of
friction. There is no dragging when
the brakes are released, besides being
less complicated and requiring prac-
tically no adjustment, operate more
efficiently and with less attention from
the motorist.
"The degrees of safety Of any
brakes, says Kublin, depends almost
entirely on the degree to which they
equalize. In other words, the same
braking pressure should be applied to
both rear wheels, in the case ow two
wheel brakes, or to all wheels, in the
case of four brakes, to get the greatest
effectiveness and the highest degree
of safety The factor of safety in Lock-
heed hydraulic brakes is unusually
high.
Are Easily Adjusted.
@The hydraulic four-wheel braking
system adopted by Moon always equal
lied perfectly and automatically with
out constant adjustment. Few brakes,
if any, that are not hydraulic can so
equalize, because only~the hydraulic
principle provides perfect and constant
automatical equalization. The only adj
justment to be made on Moon four
wheel hydraulic brakes is on the brake
bands themselves and is practically the
same adjustment that is made on or
binary two-wheel brakes. Any garage
mechanic can make the adjustment
quickly and easily when it becomes
necessary. Motor car drivers and own
ers and every one who has the main
tenance of a motor car in their charge.
will appreciate the freedom from lubri-
cation worries, for the Moon hydrau-
lie brake system requires no lubrica-
ton whatever. And with the elimina-
ton of various working parts, rattles
are eliminated.
How They Are Oiled.
sThe fluid used in operating n.y.
draulic brakes is contained in tank
located on the dash under the hood.
and in tubes leading to each brake. APP
proximately one quart of fluid. COM
posed of equal parts of glycerine or
castor oil and alcohol, operates the en-
tire system. In case of emergency. COM
mcn mbrieating oil can be used tenn
porarily, instead of the fluid. 1t is
planned to offer four-wheel hydraulic
brakes as optional equipment on all
models of Moon cars, at extra cost.
