Rear Break cylinder for 1951 Chevy 3600 truck

[Midge725]

Hello guys I have a 1951 Chevy 3600 and I'm looking for the right break cylinders for the rear. Both are pitted pretty bad and one is leaking. I found some on Jim carter truck parts but they are for a 1950 and then I found some for a 1952-53 but nothing for 51. As all ways thank you in advance

I assumed all those years were the same. I will be watching this thread for the experts to enlighten me.

Midge,

I just picked up a 3600 and plan to swap the body over to an S10 frame and trim the bed. If you're interested in these parts off my truck PM me. Happy to pull and ship them.

I didn't know they were different. Can you call Jim Carter and ask?

51 should be a huck brake cylinder with the star wheel adjuster at the end of the cylinder pictured left and , 52 up should be the Bendix like later days cylinders and the adjuster on the bottom of the shoe picture right

Rockauto sell both types

I haven't had the drums off yet it looks like I'll have to take it apart and see what I have and then order parts.
I like to try and have things on hand that way it's done all at once. Thank you for your help guys.

You can tell by the backing plate. Huck brakes have two adjuster slots at the top of the backing plate next to the fitting for the line. Bendix will have one slot at the bottom of the backing plate at 6 o'clock

Awesome thank you for the heads up and the help that makes life a little easier on me.

It's best to check anyhow as you never know if someone swapped in a later rear axle when replacing the original axle on a truck of this age.

Rock auto doesn't show cylinders for a 51 3600 from what I can find.

Looks like this truck has a Hucks by the backing plate.

That's has been the big issue with this truck. No one seams to have much for a 3600 truck. We couldn't find any emergency break cables for this year either and ended up taking e-breaks cables off of a short bed and extending it.

Has anyone had any luck on rebuild the brake cylinders?

[CraigRK]

Hi Guys,

I'm also going to need to get brake parts for a '49 3600.

I'll check the backing plate when I get a chance to see if it has Huck or Bendix brakes. Based on the rest of the truck I suspect still original Huck.

Are the shoes, cylinders, flex hoses, etc different on the 3600 to the 3100?

RockAuto lists 3100 and 3800, but very little to nothing against 3600.

TIA,
Craig

I took my rear wheel cylinders apart and honed them. I had to get the shoes relined at an "Old Timer" brake relining place. Its worth the effort to see what you can do to fix the existing cylinders. The pistons and cups seemed to be okay in my cylinders so I went went with honing and cleaning and put them back together. I was lucky that the piston, springs, and seals where in decent shape. If and when you do take the brakes out and work on them, be extremely cautious with the clips that hold the components together. The larger clip can be replace with this.

The smaller clips are impossible to find.

If the return spring is broke, it can be replaced with this.

Most all the other components are nearly impossible to find.

Awesome thank you for the information I'm planning on pulling these out today or tomorrow. We shall see how bad they look.

Craig, I don't know for sure but from what I'm seeing they are. I'm assuming that the shoes and cylinders are made a little heavier duty then what the 3100 was.
I'm also running into issues finding parts for my 3600 my plan is to rebuild what I can and save up the money to do a complete disk brake replacement in the future.
Good luck!!

Ok guys I got my brake cylinder out today and I'm a little concerned. I don't know if I can rebuild this or not with the amount of pitting that there is on the inside of the cylinder. The pitting is very close where the rubber is going to sit. A rebuild might get me through the next year or so until I can save up and get one of the brake kits to swap to all disk. But I wanted some input let me know what you guys think.

There are several companies that will sleeve the cylinder and rebuild if for you
Apple hydraulics is one I remember. Not cheap but nothing on a 3600 3800 truck is cheap when it comes to brakes and driveline.

Would that be the best choice to do then taking my chance on a cheap China remake?

I'm thinking probably so but don't know what kind of quality the new remakes are.

I think I would go with a re sleeving, They use either brass or Stainless steel depending on who does it, they can do the rebuild for about $85 a cylinder

here is another
