a good many owners seem TO feel
doubtful about their ability to care
for the braIing systems Of their We
hicles especially as regards refining
them after the bands have given evil
dence of needed replacement. There
is no reason why any car owner can
not laline his brakes if he attacks
the Job in the proper manner
1t is scarcely necessary to explain
60 the average car owner why brake
Innings wear out. When it is consid-
cred that on the composition used
to line the brakes practically the
whole pressure of a vehicle weighing
perhaps a ton and a half is suddenly
impounded while that great mass IS
travelling at considerable speed, the
owner viii not wonder at the COM
pounds tendency 10 wear out.
In actual service every time the
brakes arc applied the great pressure
eNerted induces a little wear on the
surface Of the lining, which is also
comprised a certain amount; il is
becausu Of this wear and compress
sion that tho brakes must be adjust
cd from time to time. The adjust
ments merely compensate for the
change in thickness caused by wear
and compression. A time comes when
the band is SO thin that no adjust
ment remains to compensate for the
condition, and then the brakes must
he refined. Sometimes the metal
band stretches a little and this adds
to the difficulty of making adjust
ments.
So long as the metal band wears
evenly and no metal spots show the
I;,,t, - iHrYspH
iceable. Sometimes, however. the
wear MAY be even, but tho rivets tha,
hold the band show signs of Wear.
The lining may be otherwise perfect
~ good but after the rivets begin 10
wear down the operation of refining
should not be long delayed.
In refining the brakes the operator
should know that the band must fit
perfectly and must make a good con-
tact with the drum. IL only one side
Of the lining bears on the drum IL is
obvious that the braking efficiency
is considerably reduced, in addition to
which excessive wear on parts of the
lining will be induced.
Now we come to the actual JOB OF
. refining. Before you begin have the
new lining cut to the actual size
needed. Most accessory shops keep
brake lining measured off in feet. BY
giving the make and model of the car
the owner can have the lining cut off
in proper lengths. And right here let
me saw that the most expensive brake
lining is none too good. The action
of this unit is so important to the
safety of the driver and his passen-
gers that every precaution should be
taken in replacement, particularly as
10 buying the most reliable lining that
can be obtained.
To remove the old lining the wheels
must be taken off and the brake
bands be disconnected from their
bands. In the case Of a propeller
shaft brake the floor boards will have
20 be removed. The brake rods will
nave TO be removed. usually by taking
put cotter pin and clevis. After the
bands have been taken off the parts
At the end of the axle should be
,leane1 with kerosene. Worn spots
shoulW be watched for The brake
bands and all small parts removed
should be cleaned and put in box so
hat .aey will not get out OF the way.
The old lining is next removed by
irst cutting off the rivets that hold
in place. A sharp chisel must b Fl
Employed to avoid injuring the band
DR. the rivet holes. After the lining is
emoved the brake bands should be
arefully cleaned, any burrs filed off,
and it should be ascertained that the
ivet holes are not out of shape. In
Ease fiis latter condition exists
lrift pin may be Inserted to make
hem round again.
In fitting the new lining length of
t should be laid on the band surface
n su6h q way that it fits snugly,
