Abstract
Abstract A brake mechanism wherein a bracket is attached to a small engine. The bracket comprises two rotating arms, a spring, a brake pad and cable attachments. When an operator of a small engine releases a cable attached to the brake assembly, the spring rotates an arm which further engages a brake pad for slowing the engine and stopping it. The cable may be attached to either arm for releasing and engaging the brake pad, which allows the small engine to be mounted on an apparatus in more than one orientation.
