ABSTRACT:
Because of the inverse relationship between spring actuating force generated by a compressed spring and the variable tangent angle of incidence between arcuate cam surfaces of opposed circular cam segments with cooperating cam followers, declining axial spring force, upon spring extension, is variably increased to a normal braking force of constant magnitude in a disc brake.
