bottom of the air can rod.
6 Adjust the lower nut until the brake shoes are .25 inch (6mm) away from the dyno
drum.
7 Tighten the upper nut on the air can rod down onto the brake actuating tube to
sandwich the tube between the two nuts.
8 Torque the lower nut to 110 foot-pounds.
If you cannot adjust the brakes to specification, you will need new brake shoes.
