Abstract
A brake assembly integrates both an impeller brake and a friction brake into an integrated brake assembly that provides for retarding and/or friction braking in response to a single braking action on a single brake assembly by the operator. In neutral, the impeller brake and the friction brake are disengaged from a brake hub. In a first braking position under a first applied fluid pressure, the brake hub engages the impeller brake for retarding axle rotation. In a second braking position under a second applied fluid pressure, the brake hub frictionally engages the friction brake for frictionally braking axle rotation.
