1a. Adjust the Brake Cable
The brake cable must be adjusted to ensure that the
brakes are close as possible to the wheel rim when no
pressure is applied to the brake lever but still allowing
freedom of wheel to rotate.
Using a suitable spanner or socket, loosen the cable
anchor nut until the brake inner wire/or cable is free to
move.
Pull the brake cable until the brake pads are approximately
3 to 4 mm from the wheel rim. Retighten the cable anchor
nut while holding the brake cable position.
