MULTIPLE STIFFNESS BRAKE ASSEMBLY

In some examples, a brake assembly includes a torque tube supporting a plurality of splines including a first spline and a second spline. The first spline has a first stiffness and the second spline has a second stiffness greater than the first stiffness. The braking system is configured such that, during a braking event and/or other relative motion between the stator disc and the torque tube, the first spline contacts the stator disc prior to the second spline, such that the first spline deflects and/or otherwise deforms before the stator contacts the second spline.
