This invention relates to a mounting stud retention system for use in a vehicle drum-in-hat disc brake assembly. The brake assembly includes a backing plate and a drum-in-hat adapter. The backing plate has a centrally located aperture and a plurality of first openings formed therein about the centrally located aperture thereof and a plurality of second openings formed therein. Each of the first openings has at least one raised tab provided thereon adjacent the opening. The drum-in-hat adapter has a centrally located aperture and a plurality of openings adapted to be aligned with the first openings of the backing plate. The brake assembly includes a fastener extending through each of the second openings of the backing plate and into the drum-in-hat adapter to thereby secure the backing plate to the drum-in-hat adapter. The brake assembly further includes a mounting stud disposed in and extending through each of the first openings of the backing plate and the openings of said drum-in-hat adapter to thereby secure the drum-in-hat adapter to an associated component of the vehicle. In accordance with the present invention, the raised tab of the backing plate is operative to capture and retain the mounting stud in the openings of the backing plate and the drum-in-hat adapter prior to assembly of the vehicle drum-in-hat disc brake assembly to the vehicle.
