Abstract
A brake retractor assembly () for a vehicle, such as an agricultural vehicle, includes a brake housing () and a brake cover () defining a friction chamber (). A brake piston () is arranged within the friction chamber () and coupled to the brake cover () by a bolt () including a first end () coupled to the brake cover () and a second end () coupled to the brake piston (). A portion of the second end () passes through the brake piston () via a bore () defined in the brake piston () and is fixedly retained to the brake piston (). An actuation system () is coupled to apply an axial force to the brake piston (). Activation of the actuation system () results in axial movement of the brake piston () in a first direction (). Deactivation of the actuation system () results in axial movement of the brake piston in a second direction (). Axial movement of the brake piston () in the second direction () is limited by the fixed retention of the bolt to the brake piston.
