1. A brake pad retractor system, comprising:

  • a torsion arm having a free end portion configured to contact a brake pad of a brake system, and an opposite end portion having an adjustable split ring;

    a torsional mount comprising a pin and an arrangement to support the pin from a housing portion of a brake system at a location adjacent the brake pad, said torsional mount cooperative with the torsion arm such that the split ring of the torsion arm is mounted on the pin of the torsional mount, and the torsion arm has an angular relation with the torsional mount and may be sprung responsively to at least some movement of a brake pad in response to operation of a brake system;

    the torsional mount operative such that upon movement of a brake pad by a first distance, the torsion arm is sprung and communicates an action upon the brake pad through a contact between the torsion arm and the brake pad, the communicated action sufficient to positively retract the brake pad upon release of the brake system;

    the torsional mount further operative such that upon further movement of a brake pad beyond the first distance the angular relation between the torsion arm and the torsional mount is adjusted responsively to the further movement;

    whereby the positive retraction of the brake pad is maintainable as the brake pad undergoes wear.
