tniH tnht no dugubtment remains
to compensate for the condition
and then the brakes must be re-
lined 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
brake lining may be considered
serviceabie. Sometimes, however.
the wear may be even, but the
rivets that hold the band show
signs of wear. The lining may. be
otherwise perfectly good, but after
the rivets begin to wear down the
operation OF refining should not be
long delayed.
In refining the brakes the opera
tor should know that the band
must mt perfectly and must make a
good contact with the drum. II
only one side of the lining bears
on the drum 1t II obvious that the
braking efficiency Is considerably
reduced. in addition to which ex-
cessive 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 OF In
feet. By giving the make ana
model Of the car the owner can
have the lining cut off in proper
lengths. And right here let me
say that the most expensive brake
lining Is none too good. The action
of this unit Is SO important to the
safety nf tho Arfuar r.
sengers that every precaution
should be taken In replacement.
particularly as to buying the most
reliable lining that can be obtained.
To remove tho old lining the
wheels must be taken of and the
brake bands be disconnected from
their bands. In the case of a pro-
peller shaft brake the floor boards
will have to be removed. The brake
rods will have to be removed. usu-
ally by taking out a cotter pin and
clevis. After the bands have been
taken OF the karts at the end Of
the axle should be cleaned with
kerosene. Worn spots should be
watched for. The brake bands and
all small parts removed should he
cleaned and put in a box SO that
they will not get out of the way.
The old lining is next removed by
first cutting of the rfvets that hold
Il in place. A Sharp chisel must be
employed to avoid injuring the banI
or the rivet holes. After the lining
is removed the brake bands SHOULD
be carefully cleaned. any burrs fileo
of. and II should be ascertained that
the rfvet holes are not out of shape.
In case this latter condition exists a
drift pin may be inserted to make
them round again.
In fitting the new lining a length
OF IL should be laid on the band
in such a way that II fits
leaving slightly over an
inch at the end. Cut the lining with
a hacksaw. To avoid measuring
over again use this piece as a pat
tern by which to cut of the others.
Next mark the lining so that holes
may be drilled to proper places TO
accommodate the rivets. with the
lining snugly in place on the band
force an anvil through each rivet
hole and into the lining.
This is very important, because X
the holes are not accurately drilled
the band will not Mt closely. as IL
must IL it is to do it's work proper
ly.
After the holes are drilled in the
lining they must be countersunk
little so that the rivet heads will be
beneath the lining surface. II the
car owner cannot do the counter
any repair shop will do :.
at a small cost.
The lining countersunk is now:
ready for riveting to the band. Some
is necessary, or the rivet
support may be placed in a wise. A
rivet is inserted in one of the holes
and the head of the rivet Is placed
against the wise. The head of the
rivet is now pounded with a riveter
and hammer. The first few blows
may be struck with the hammer and
the final ones with the riveter in
terposed. Before the rivet is pound
ed down be sure that the lining sets
snugly against the band. II 1t is
found that through come error tho
lining does not lie smooth and close
to the band. It is better to cut of
one or two rivets and begin again,
rather than risk having a lining
that does not operate properly.
In remounting the lined bands 1t
may be necessary to use a hammer
or mallet to get a good At of the
band around the drum. The band
must be concentric with the drum.
but in handling and riveting the
band may be spread out Of shape %
little, so that a delicate application
of force may be needed to get IL
