ADJUSTING THE BRAKES
When the brakes are not applied, the brake pads should be 2 to
4mm from the rim. If the brake pads are too close to the rim,
the brake is too tight. Brake pads should be aligned with the rim
surface. If the brakes are not properly adjusted, take your
bicycle to your local bike shop for service. Every month, make
sure you check the brake cables on your bicycle for kinks, rust,
broken strands and frayed ends. Also check the housing for
bent ends, cuts, stretched coils, and wear. Replace any part
which does not pass inspection.
Every month inspect the brake pads on your bicycle for wear.
Brake pads have shallow grooves in their braking surface. If any
of these grooves are less than 2 mm deep, replace the pads.
ADJUSTING THE BRAKE PAD
CLEARANCE TO THE RIM
To increase the pad clearance, turn the barrel adjuster clockwise.
To reduce the pad clearance, turn the barrel adjuster counter-
clockwise. The barrel adjuster is located at the top of the brake
itself, where the cable enters the caliper.
If the brake pads cannot be adjusted properly in this manner,
loosen the cable clamp bolt and re-attach the cable. Turn the
adjusting barrel clockwise so the threads on the adjusting barrel
are not exposed above the caliper, or outside the lever. Hold the
brake pads against the rim, pull the cable snug, and tighten the
cable clamp bolt to the torque specification (see Torque Settings)
ADJUSTING THE ALIGNMENT
OF THE BRAKE PADS
Loosen the brake pad fixing bolt and align and tighten
the brake pads.
After the brakes are adjusted, test the brakes. Apply maximum
braking force to the levers. Ensure the cable does not slip, the
pads close toward the rim at the right angles and the pads do
not contact the tyre.
