1965-82 Corvette Right Front O-Ring Caliper. O-Ring calipers come with a specially designed 45 degree parting line seal with matching piston which ensures four good sealing surfaces. These calipers work well for preventing leaks on cars that are not driven frequently. Each caliper is bored and sleeved back to original equipment specs with stainless steel sleeves, polished to a 4 micron finish. Each caliper is then carefully cleaned and shot-blasted with all threaded holes cleaned and tapped. Each caliper is assembled with new pistons, new bleeders, pad pins, new rubber seals and dust boots. Every caliper is tested with high pressure nitrogen on special flaw detection equipment. Price Includes $75 Core Deposit. Calipers come with a lifetime warranty on the stainless steel sleeves. Rubber components are under warranty for one year.
