There are a number of ways you can check
that your brakes are working properly.
With your weight on the handlebar, squeeze
the front brake lever hard & try to push the
bike forwards. It should be impossible to
move the bike without skidding the wheel or
lifting the rear wheel. Then do the same to
the rear brake. When you squeeze the brake
lever it should not come up to the bar, if
it does you will need to adjust the cable.
