Corvette caliper o'ring upgrade kit: 65-82 Rear (2)This is a new upgrade kit for the standard rear Corvette factory Caliper.. what will often develop leaks especailly when the car basically gets minimal use. THIS IS FOR TWO REAR CALIPERS 8 x boots & seals & 8pistons (not the caliper s which is shown for example only) This is a better value.. improved sealing caliper kit for the basically pretty crook Corvette caliper design that is often just maintainance hungry, especially when then cars are not used
