Adjustment of most British brake systems is a simple operation which should be done regularly. The general method is to turn the adjusters clockwise until the shoe comes up against the drum, "clicking back" until the wheel turns free. Most manuals recommend one click to free the drum, but two or more are usually needed. Rotate the wheel by hand to check the adjustment. A slight "scuff" is permissible, but no drag must be present. Check the drum for concentricity if the adjusters must be backed off an excessive amount. On twin cylinder systems, adjust each shoe in turn.
It is advisable to remove the brake drums at least once each year to inspect the linings and drum surfaces.
