Book Excerpt: Four-Stroke Motorcycles: Early 1960s to 1970s Repair Manual FRAME AND COMPONENTS: BRAKES

Front and rear brake action should be checked each time before the motorcycle is ridden. The front brake hand lever should never be compressed against hand grip even with brake fully applied. Normal minimum suggested clearance (as shown in Fig. 2-40) is approximately 7/8 inch with front brake locked. Adjustment is accomplished at cable adjusters shown in Fig. 2-41 and Fig. 2-42 or at hand lever end of cable. Rear brake pedal should be compressed approximately 7/8 inch (as shown in Fig. 2-43) with rear brake locked. Adjustment is normally accomplished as shown in Fig. 2-42 or 2-44. When adjusting brakes, setting should not be so tight that wheels are hard to turn with brakes released. Typical exploded views of brake assemblies are shown in Figs. 2-45, 2-46 and 2-47. On dual cam brakes, rod (5-Fig. 2-46) should be adjusted as follows: Disconnect brake cable from lever (1F) and remove connector pin (6). Adjust length of connector rod (5) until holes from pin (6) in lever (1F) and connector rod (5) are aligned without moving levers (1F and 1R). Reinstall pin (6) and adjust control cable.
