A method for repairing worn brake assembly holes on a highway trailer axle assembly including a cam shaft hole, and first and second anchor pin holes and including an axle stub extending from an end thereof, comprising the steps of aligning a boring tool, having a tool axis, with each brake assembly hole axis by aligning the tool axis parallel with the stub axis; positioning the tool axis at a distance from the stub axis equal to the distance of the brake assembly hole axis from the stub axis; and positioning the tool axis at an angular position relative to the brake assembly hole axis that is equal to the angular position of the brake assembly hole axis relative to the axis of another of the brake assembly holes. The aligned boring tool is then driven to bore an oversize hole through the worn brake assembly hole such that the worn brake assembly hole, including any worn extremities thereof, is consumed by the oversize hole, leaving a substantially cylindrical oversize hole. An oversize bushing is installed in the oversize hole having an inner diameter suitable to accommodate a brake cam shaft or anchor pin therethrough. An apparatus is also provided.
