About twenty years ago I was working with an automotive foundation brake supplier when catastrophe struck. One of this company’s calipers utilized a Collette Style Pin brake caliper design. These calipers operate by sliding along a two piece pin system. There is a Collette Pin with a tapped hole in the head and a Mounting Bolt. The Mounting Bolt connects the face of the Collette Pin to the back side of the Piston Body Flange, providing unfettered access for the caliper bracket to slide along these pins when the brake is functioning.
