MAINTENANCE
Brakes
It is especially important to inspect your HERO in the first weeks of use. The
brake cables can stretch and bolts can loosen.
Once the brake pads are worn down to their wear marks
replace before using the bicycle again. Replacements
are readily available from us at hornit.com or from your
local bike shop.
It’s an important habit to check both of the brakes before moving off at the
beginning of a ride and also after a fall as the cables can be snagged or
damaged.
Check that the brakes work smoothly and the levers return to their open
position and the callipers reopen enough not to touch the wheel rim.
You can see this by lifting the wheel off the ground and checking it spins freely.
If the lever can touch the handlebar and the bike can still be pushed forward it
is definitely time to adjust them.
• Unhook cable end from the cable hook on the calliper arm.
• Unscrew the barrel adjuster 3 or 4 turns away from the lever.
• Loosen the brake cable pinch bolt.
• Squeeze the 2 calliper arms so that the pads touch the wheel braking
surface.
• Adjust the pads so they sit true to the top edge of the rim sidewall, but not
touching the tyre.
• Re-tighten the pinch bolt (6Nm).
• Check the braking action so the brake lever engages before touching the
handlebar and the cable noodle can still be removed from its cradle.
• Re-tighten the barrel adjuster which will cause the brake pads to come
away from the rim sidewall and allow the wheel to spin freely. Use the barrel
adjuster for fine adjustments. Reset the cable using the cable pinch bolt for
larger adjustments.
• Centre the calliper arms so that they both contact the wheel at the same
time and return to a neutral position away from the rim. If one of the calliper
arms does not return after braking you can adjust the spring tension on
both sides by turning the spring adjustment screws on the callipers. Turning
the spring adjustment screw clockwise will cause that calliper arm to come
further away from the wheel.
Disconnecting the Brakes
In order to remove the wheel to repair a puncture or for transport the brakes
need to be disconnected (see Front wheel p6).
