It is imperative that the leading edge of each brake shoe comes into contact with the brake drum simultaneously, if maximum braking efficiency is to be achieved. Check by detaching the clevis pin from the eye of one end of the threaded rod, so that the brake operating arms can be applied independently. Operate each arm at a time and note when the brake shoe first commences to touch the brake drum, with the wheel spinning. Make a mark to show the exact position of each operating arm when this initial contact is made. Replace the clevis pin and check that the marks correspond when the brake is applied in similar fashion. If they do not, withdraw ihe clevis pin and use the adjuster to either increase or decrease the length of the rod until the marks correspond exactly. Replace the clevis pin and do not omit the split pin through the end which retains it in position. Recheck the brake lever adjustment before the machine is tried on the road.
