Abstract
A method of fabricating a brake pedal rod comprising the steps of forming an end-piece from a readily machinable material having an aperture forming means for attachment to a brake pedal. A shank piece is formed of materials preferably having greater strength under compressive load than the end-piece, and then a flat end of the shank piece is attached to the end-piece to form a pedal rod, said end having spaced arcuate surfaces in threaded engagement with the end-piece preferably along interference threads capable of resisting unthreading forces of the order of 5-40 inch pounds or more.

A method of fabricating a brake pedal rod comprising the steps of forming an end-piece from a light weight, readily machinable flat material having an aperture in one end thereof for attachment to a brake pedal, forming a shank piece with an internally threaded hollow end portion of material having greater strength under compressive load than the end-piece, and then attaching a flat other end of the end-piece to the shank piece hollow end to form a pedal rod by threading said flat other end having spaced arcuate threaded edge surfaces into threaded engagement with the internal threads of the hollow end of the shank piece along interference threads capable of resisting unthreading forces of the order of at least 5-40 inch pounds or more.
A method of fabricating a brake pedal rod comprising the steps of forming an end-piece from a readily machinable flat material, forming a shaft piece with an internally threaded hollow end portion of readily machinable material, and then preparing a connection between the end-piece having a flat end with spaced arcuate threaded edge surfaces by threading same into engagement with said internally threaded hollow end portion of the shaft piece, and forming said shaft piece with flattened spaced surfaces separated by spaced curved surfaces in threaded engagement with said spaced arcuate threaded edges of said end-piece.
