Changing and Adiusting Brake Shoes
lf
brake
shoes have
no
thread
or
if any part of the
rubber
block
wears
down
to 1/8" from
the metal backing,
it
is necessary
to
replace
them.
To obtain
the performance
built into your bicycle, be
sure
to only
use
top quality
brake
shoes.
Remove
the brake
shoes
by
using a
wrench
to detach
the nut
and washer.
After positioning new brake shoes,
replace
the washer
and nut
to
their original
location, being
careful to observe
the adiustment instructions illustrated below.

position they will
interfere
with folding
and
unfolding.To

loosen the mounting nut
and maneuver
to the proper position. Always
be

The adjustment
procedures is similar
for
these
two
types
of
caliper brakes,
with any deviations being
clearly pointed out in the
following paragraphs.
A.
Ad
justment
of
Brake BodY
For bcst braking
action,
it
is
vital
that
brakes are
mounted so as
to
leave
a
distance
of approximately
1l16"
between each brake shoe
and the
rim.
(Fig
2).
Note:
lf
either wheel is
not in
alignment
with the
bicycle frame, rubbing
will
occur
between
the rim and the brake
shoes.
To correct this, re-align the
wheel
as
instructed in section 6.3.12
of this
manual.
lf the
front
brake shoes are
not
equally spaced,
tap
down lightly on
one
side
of
the "return spring"
with a
screwdriver.
lf
this does
not corrcct the
prob-
lem,
slightly
loosen
the mounting bolt and repeat
the tapping procedure. For
the
rear
brake, adiustment should be made
by
slightly loosening
the mounting
bolt
and tapping
the top of the brake arm
until
the brake
shoes
are
evenly
spaced.
Always be
certain
that both
front
and rear
mounting bolts
arc securely tightened
before
riding the bikc.
lf
either one
of
the
mounting bolts are
stripped and can-
not
be
properly tightened,
or lf
it
is
damaged
or bent, replace
it
immediately.
