Brake System
The brake system employed is an outward expand-
ing type shoe, actuating on the front wheel. In ope.
r ation. the acti on of t ile rig ht br ake lever, t hrough lhe
brake wire and brake arm, forces the cam to rotate.
and this in turn forces the brake shoe. incorporated in
the front wheel hub, to move outward and come in
contact with the inside of the hub.
On the rear wheel, and inward contracting type
brake is employe d. The action o f the left br ake lever
actuates the r ear brake cam. forcing the brake shoe
to move inward and clamps the final driven shaf l flange.
