I just got home with my new truck. It's a 63 C60 Fire truck. It has a dual master cylinder set up with one side for the clutch and one side for the brakes. Neither of which work properly. I pulled the master cylinder off and it looks to me like the pistons are stuck all the way in. They're about an inch in from the snap ring that keeps them from coming out. I was wanting to either rebuild this one or know where I can get a replacement. Any help would be appreciated.
