4.2.1. Position of Brake Arm
The distance between Brake Arm (2) and Brake Slider (7) must be in 1 ± 0.5mm as shown in
Fig. 4.1. The distance can be adjusted by adjusting the position of Brake Arm (2) with two
screws (5).
4.2.2. Brake Torque
The brake torque is applied mechanically. The pressure is set by variable spring force. While
making these measurements and adjustments, be careful not to bend the brake bands. As brake
torque will change after cleaning, brake drums and brake shoes should be cleaned only when
absolutely necessary. If cleaning is required, use alcohol.
Brake adjustment is made with no power to G24S/G16S.
