Disk brake assemblies having springs for biasing friction pads

A disk brake assembly comprising:

• a disk rotor having a central axis;
• a pair of friction pads arranged and constructed to be pressed against the disk rotor from opposing sides in an axial direction of the disk rotor, and
• a return spring coupled to the friction pads and arranged and constructed to bias the friction pads in directions away from the disk rotor, wherein:
• the return spring includes a straddle portion, a pair of extensions and a pair of engaging portions,
• the straddle portion is disposed radially outside of the disk rotor and extends in the axial direction across the thickness of the disk rotor in order to straddle the disk rotor,
• each of the extensions extends from the straddle portion, in a direction substantially toward the central axis of the disk rotor, to an engaging position that is proximate to a centerline of one of the friction pads with respect to a radial direction of the disk rotor,
• each of the engaging portions is disposed at one end of each extension and engages one of the friction pads at the engaging position.
