The Stovebolt Site Forums The Parking Lot Big Bolts 1965 C60 Rear Wheel Cylinders

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.

Hy IHBoilermaker, could you tell us the part number of the Raybestos wheel cylinders you're inquiring about?

WC37042 is the Raybestos number, 3/8 threads for brake line.

Hy IHBoilermaker, it looks like the crossover line goes up from the bottom wheel cylinder to the top cylinder inside the brake drum leaving only the bleed screw on the outside of the backing plate at the top. Both wheel cylinders are available at RockAuto, Raybestos p/n WC37042 $20.79, and p/n WC18196 $27.79, hope that helps.

Ok this is kind of what I figured. The thing that was throwing me of was that one cylinder was 3/8 inlet and the other was 7/16 inlet but upon further research I see that these will in fact get the job done. Thanks for your help.

Thanks again 3B I just order all 4 rear wheel cylinders for my Viking from Rock auto

Hy pkd66, welcome, I have many catalogues and parts books so I can search by part number, most sites do not have the ability to search for truck parts heavier than one ton. If you will tell us what in particular you are looking for we may be able to help you.
