Abstract
A brake assembly includes a wheel hub having a radially-outer diameter and a plurality of splines that are spaced apart around the radially-outer diameter. A brake disc is mounted on the wheel hub and has a radially-inner diameter and a plurality of pockets that are spaced apart around the radially-inner diameter. The pockets receive the splines such that the brake disc rotates with the wheel hub. Each pocket has opposing axially-extending side walls. Each side wall has an outwardly-chamfered outboard end and an inboard locking recess. A plurality of spacers are radially disposed between the splines and pockets. Each spacer has opposing arms connected together by a brace. Each arm has an outwardly-chamfered end and outwardly-projecting locking foot which together mate with the outwardly chamfered outboard end and inboard locking recess, respectively, so as to lock the spacer in the pocket.
