Patent ID: 8453804

Claim:
A caliper for a retrofittable disc brake system of a vehicle having an axle, comprising: a first caliper half; a second caliper half not integrally formed with the first caliper half, the second caliper half in spaced apart relation to the first caliper half to permit rotation of a brake rotor disposed therebetween; only one of the first and second caliper halves being integrally formed with a mounting plate for fixedly mounting the caliper on the vehicle proximal the axle; a brake pad retaining mechanism for retaining brake pads on each caliper half; a brake pad engaging mechanism for engaging the brake pads against the rotor on each caliper half; at least one joiner plate for connecting said second caliper half to said first caliper half in a spaced apart relationship, having a first attachment position on said at least one joiner plate for attachment to the first caliper half and second attachment positions on said at least one joiner plate distantly spaced from the first for selective attachment to the second caliper half; wherein the at least one joiner plate is fixedly and removably attached to the first caliper half and second caliper half at said first and second attachment positions to thereby permit attachment of the caliper halves at a plurality of spaced-apart distances to accommodate brake rotors having different thicknesses between the caliper halves.
