A torque plate barrel for a braking system includes a torque tube having a first end and a second end spaced from the first end along a central axis. The torque tube has an inner surface and a pedestal. The pedestal has a foot portion disposed and sized for engagement with an axle and a head portion disposed and sized for engagement with the inner surface of the torque tube. The head portion of the pedestal includes a first radius of curvature defining a first surface facing toward the first end of the torque tube and a second radius of curvature defining a second surface facing toward the second end of the torque tube. The pedestal may include different cross sectional geometries extending circumferentially over different angular segments about the inner surface of the torque tube barrel.
