Abstract:
An improved on-vehicle disk brake lathe which attaches to a wheel hub having a brake disk attached thereto, the wheel hub having a hub axis about which both the wheel hub and the brake disk rotate, the brake disk having a first disk surface and a second disk surface, the disk brake lathe having,a frame attachable to the wheel hub and having a lathe axis, means for aligning the hub axis with the lathe axis, a drive mechanism for rotating the wheel hub about the lathe axis, a first tool bit which is engagable with the first disk surface, a second tool bit which is engagable with the second disk surface, and means for advancing the first tool bit and the second tool bit along a feed path which is normal to the hub axis, the improvement comprising:a first tool holder for supporting the first tool bit, said first tool holder being translatably engaged with respect to the frame such that it traverses a first tool holder path which is parallel to the lathe axis; means for moving said first tool holder along said first tool holder path to adjust the spatial separation between the first disk surface and the first tool bit; a second tool holder for supporting the second tool bit, said second tool holder being translatably engaged with respect to the frame such that it traverses a second tool holder path which is parallel to the lathe axis; means for moving said second tool holder along said second tool holder path to adjust the spatial separation between the second disk surface and the second tool bit; a displacement gauge connected between said first tool holder and said second tool holder so as to respond to changes in the spatial separation therebetween, said displacement gauge providing a gauge signal responsive to said changes in separation; and means for reporting said gauge signal of said displacement gauge.
