Some brakes have a quick release mechanism to allow easier wheel removal. Whenever you adjust the brakes,
make sure the quick release mechanism is in the closed position.
Never ride unless the quick release is firmly locked in the closed position.
Lubrication
The brake lever and brake caliper pivot points should be oiled with
2-3 drops of light oil at least every three months to ensure smooth
operation and to reduce wear. Cables should be greased along
their entire length, after removing them from their casings, at least
every six months. Always grease new cables before fitting.
Adjustment - Sidepull Calipers
Minor brake adjustment can be made via the cable adjusting bar-
rel, usually located at the upper cable arm. To adjust, squeeze
the brake pads against the rim, loosen the lock nut and turn the
adjuster Brake pad clearance should be a maximum 2mm from
the rim. When correct, re-tighten the lock nut. If the pads cannot
be set close enough to the rim in this manner, you may have to
adjust the cable length. Screw the barrel adjuster 3/4 of the way in,
squeeze the pads against the rim, undo the cable anchor bolt and
pull the cable through with pliers. Re-tighten the cable anchor bolt
and apply full force to the brake lever to test, then fine tune using
the barrel adjuster. If one pad is closer to the rim than the other,
loosen the fixing nut at the back of the brake, apply the brake to
hold it centered, and re-tighten the fixing nut.
