1-11. BRAKE MECHANISM
The axle drive shaft is normally free to rotate, because the brake band is held clear of the brakedrum
by the brake return and brake adjusting springs. When the control lever is operated to the rear
(operate brake position), the idler arm pivots around the shaft and causes the cams around the lever
arm to rotate. As the cams rotate, force is applied to the one end of the brake band and through the
cam stop and the adjustment bolt to the other end of the brake band. This action pulls the ends of the
brake band together, compressing the brake return springs and causing the brake band to close
around the brakedrum. Friction between the brake band and the brakedrum produces the braking
action. When the control lever is released (neutral), the brake return springs expand, forcing the ends
of the brake band apart and releasing the friction between the band and the drum. In the released
condition, the brake band is held clear of the drum by the brake return and the brake adjusting
springs. Centering of the band about the drum is accomplished by adjustment of the anchor bolt and
the two mounting bolts. The adjustment bolt at the bottom of the brake band provides adjustment to
compensate for wear of the brake band.
