In style with the times Performance Machine introduced their ''Vintage Caliper''. Contrary to the looks it is not a 2-piston caliper; it is designed to have a vintage flair; but modern 4-piston engineering is used. It is a mixture of technical excellence and an aesthetic work of art. The ''Vintage Ribs'' are actually reinforcing ribs to decrease flexing; improving brake feel; control and aid in cooling when the going gets hot. The bodies; or caliper halves; are CNC machined from one-piece billet bar; a much more homogeneous material; giving it a natural material strength advantage over regular cast calipers. When it comes down to the nitty gritty; the PM Vintage will not only cut the cake; but cut it better.
