| This master cylinder is a direct bolt on and a direct copy of the original masters that came on the 70-71 z's. Originally the front reservoir went to the front brakes and that is the way that this cylinder is made. In 72, they changed the master so that the front reservoir went to the back brakes. This cylinder has limited availability and is out of production. This production run was made in 2002 approximately so it is NOS. Once these are gone I doubt that they will ever become available again. Last update 11/09 |
