Caliper type disc brake

A disc brake and wheel assembly comprising:

• a rotor having friction faces on the first and second sides thereof;
• said rotor being connected to a rotatable hub;
• a wheel being connected to said hub with an axially extending annular rim;
• a stationary torque member disposed at one of the first and second sides of the rotor;
• said torque member having a pair of ears radially extending outward of said rotor;
• said caliper straddling said rotor and located radially inward of said rim of said wheel;
• first and second brake shoes adjacent the first and second sides respectively of said rotor;
• a one-piece guide element for slidably mounting a mounted portion of said caliper to one of said ears of said torque member with said torque member interposed between said mounted portion of said caliper and said rotor such that said caliper is movable in a transverse direction to said rotor faces along said guide element;
• said guide element spanning said rotor and passing through an internally threaded aperture in said one ear of said torque member and threadably engaged therewith;
• said guide element comprising a pin with spaced apart first and second non-threaded portions with a threaded section therebetween engaging said one ear of said torque member;
• the first non-threaded portion extending through an aperture in the caliper and the second non-threaded portion extending through an aperture in the first brake shoe, said non-threaded portions being on opposing sides of said one ear of said torque member;
• said second non-threaded portion having a larger radius than said first non-threaded portion and said threaded portion of said pin and said apertures in said torque member and said caliper;
• said aperture in said first brake shoe being larger than the apertures in said torque member or caliper to slidably receive said second non-threaded portion;
• said first brake shoe being mounted on said guide element on an opposite side of said rotor from said mounted portion of said caliper such that torque applied to said brake shoe from said rotor is transferred through said guide element to said stationary torque member;
• actuating means for moving said brake shoes into and out of engagement with said friction faces of said rotor;
• retaining means for retaining said second brake shoe on the same side of said rotor as said mounted portion of said caliper in an operable position between said actuating means and said rotor and in torque transfer relationship directly with said torque member;
• the caliper and first brake shoe being slidably mounted on the first and second non-threaded portions respectively of said pin for movement transverse to said rotor;
• said first brake shoe having radially extending ears with said caliper being interposed between said ears of said first brake shoe;
• said first brake shoe trapped between said hub, said caliper, and said rotor when said caliper is positioned between said ears of said torque member, straddling said rotor, and radially inside said rim of said wheel.
