Abstract:
1. A brake system for a wheel comprising: a downhill activator having an inner ring and an outer ring and a spring; said inner ring and said outer ring being configured such that the said inner and outer ring are mateable to comprise a cooperatively rotating body; said spring being configured to bias said inner ring and said outer ring in an un-mated position; a disc brake integral with said outer ring, whereby the speed of rotation of said disc brake directly affects the speed of rotation of said outer ring; a wheel axle integral with said inner ring, whereby the speed of rotation of said wheel axle directly affects the speed of rotation of said inner ring; a pendulum gravitationally disposed relative to said inner ring such that when a predetermined angle of decline is reached said pendulum overcomes the spring bias of said inner ring to place said inner ring into cooperative movement with said outer ring; whereby braking force applied to said disc brake is applied to said wheel axle.
