Set Parking Brake
When the parking brake lever is moved back, lever located on the end of the parking brake cable moves strut in the direction of "F" with point "P" utilized as a fulcrum.
The strut then presses brake shoes A and B against the drum. These brake shoes utilize a floating design and are lightly supported by hold-down pins. The force applied to brake shoe A, and the reaction force of "F" applied to brake shoe B via point "P" provide brake application when the shoes are pressed against the brake drum.
