DISC BRAKES
1. Check the tightness of the six disc mounting bolts (Figure
16) that are holding the brake rotor to the wheel. If you
need to remove these bolts, be sure to use a thread-locking
compound when reinstalling them.
2. Make sure the two bolts securing the caliper adaptor
bracket to the fork are tight (Figure 17 – A).
3. Thread the brake cable through the caliper as shown and
secure it with the cable fixing bolt (Figure 17 – B).
4. Loosen the two caliper mounting bolts enough to allow
the brake caliper to float freely (Figure 18).
Drivetrain
The drivetrain of a bicycle refers to all parts that transmit power
to the rear wheel including pedals, chain, chain wheel, crank set
and freewheel.
Pedals
Pedals should be inspected every month, taking note of the
following areas:
Check correct tightness into the crank arms. If pedals are
allowed to become loose, they will not only be dangerous but
will cause irreparable damage to the cranks.
Check that pedal bearings are properly adjusted.
Move the pedals up and down, and right to left, and
also rotate by hand. If you detect any looseness or
roughness in the pedal bearings then adjustment,
lubrication or replacement is needed.
Ensure that the front and rear pedal reflectors
are clean and securely fitted.
