Abstract
A brake assembly () for an air turbine starter () includes a brake cylinder () located in the air turbine starter (). A brake piston () is located at least partially within the brake cylinder () and slidable therein. A biasing member () biases the brake piston () toward a turbine wheel () of the air turbine starter () applying a braking force to the turbine wheel () and defining a piston chamber () between the turbine wheel () and the brake piston (). A through opening () in the brake piston () into the piston chamber () is configured such that a flow of fluid through the through opening () into the piston chamber () applies a force to the brake piston () sufficient to overcome the bias thereby allowing rotation of the turbine wheel ().
