ADJUSTMENT



Make sure that the brake operating handle or foot pedal is fully released. Check the operating linkage and the cable to make sure that they don't bind. If necessary, free the cable and lubricate it. Rotate the brake drum until one pair of the three sets of holes are over the shoe adjusting screw wheels in the brake drum as a fulcrum for the brake adjusting tool or a screwdriver. Rotate each notched adjusting screw by moving the handle of the tool away from the center of the driveshaft until the shoes are snug against the drum. Back off seven notches on the adjusting screw wheels to secure the proper running clearance between the shoes and the drum.

The brake operating lever position must be properly set. The setting point is a measurement between the lever and the brake backing plate at the closest point between the two. The proper gap is 3 / 32 ". Rotate the ball nut to adjust the clearance.
