I am overhauling the brake system on my 65 C60 and I have a question about the rear wheel cylinders. My system has a line that comes in to the bottom cylinder, then a line that branches out of the front of the bottom cylinder and up to the upper cylinder. This cylinder is equipped with a bleeder screw on the back side. The upper cylinder does not have a spot for a line to thread into the back. It is just solid. I found wheel cylinder info on raybestos.com. It seems the only cylinder available is the lower one that has the threaded line holes on both sides. Would I just put a threaded plug into one of these and use it for the upper or what? They current cylinders are in real good shape but I'm having a hard time find replacement pistons for the upper as they are sort of pitted. Are these pistons available? Rebuild kits don't come with them. The bore is 1 1/2.
