REMOVING MINOR CABLE STRETCH:
If the brake pads are more than 1/8" from the wheel rim, cables have
stretched (or brake pads have worn) and adjustment is necessary. To
remove minor brake cable stretch, you can use the brake lever
adjuster barrel. Clamp the brake pads against the wheel rim with a
"third hand" tool or a toe strap until the brake pads are 3/32" from the
rim. Turn the lock nut counterclockwise one-half turn and then turn
the adjuster barrel itself counterclockwise until cable slack is
removed. Re tighten the adjuster barrel lock nut. If more adjustment
is necessary, (i.e. if your brakes are still too tight or too loose), you
will need to make the major cable length adjustments. Cable length
adjustment is a critical adjustment and recommended for experienced
bicycle mechanics only.
"TOE-ING IN" BRAKE PADS:
If you are experiencing squealing brakes, you
Cable Pinch Bolt
may need to adjust the "toe-in" on your
brakes. As a general rule, the leading edge of
the brake pad should contact the rim before
the trailing edge of the brake pad. If you are
experiencing squealing brakes, it is likely this
adjustment is not correct. Toed-in brake pads
should have no more than 1mm deviation
from one end to the other.

experienced bicycle mechanics only.
BRAKE PAD REPLACEMENT:
Brake pads should be replaced before the grooves in the surface of the
pad are worn away. Also, brake pads can become age-hardened and
require replacement. To ensure even braking, it's a good idea to
replace all four pads at once rather than just one or two at a time.
BRAKE CABLES
Inspect brake cables for wear before every ride, checking for kinks,
broken strands and frayed ends. Inspect the cable housing for wear. If
you find a problem with your brake cables, do not ride your bicycle
until the problem is repaired.
A NOTE ON HANDLEBARS:
Raising or lowering the handlebars using stem adjustment can affect
the adjustment of your bicycle's brakes. Make sure after you adjust the
handlebar height that you check the brakes for proper operation.
