Abstract
Disclosed are systems and methods for reducing friction on a brake arm of a caster wheel brake. A washer can be positioned between the brake arm and the support arm to reduce friction in this area. Lubricant can also be provided between the brake arm and the support arm, and also between the brake arm and the brake cam, to reduce the friction in these areas. The presently disclosed embodiments therefore allow less force to actuate the brake arm as compared to prior art caster wheels.
