DEFINITION

Classification: 188/24.14

Having means to increase braking force (e.g., self-energizing brake, etc.):

(under subclass 24.12) Apparatus including automatically operating means to increase the effective force exerted upon the vehicle when the brake is actuated.

(1) Note. Common to this subclass, and those indented hereunder, is a vehicle having at least one caliper-type brake and means for automatically increasing the effective braking force upon the vehicle without proportionately increasing the force exerted upon the actuator by the vehicle's operator. A so-called self-energized brake is one type of this subject matter.
