8. TESTING BRAKE FUNCTIONS

For detailed instructions on brake adjustments, please see page 27.
To test the function of the front hand brake, lift the front of the bike and spin the wheel. The
wheel should not rub on the brake pads. Next, squeeze the brake lever and take note of
the brake pads contacting the side of the wheel. The pads should contact the rim on both
sides at the same time. Finally, hold the brake lever firm and try to move the bike forward.
The brake should hold well enough to keep the wheel from moving. Repeat these steps for
the rear wheel. (See Figure 1.)
To test a coaster brake, lift the rear wheel and pedal the bicycle with your (see Figure 2)
other hand. While the wheel is spinning, push the pedal backwards to engage the coaster
brake. The wheel should stop completely.
