'66 CJ-5 10" Hardware

I can't seem to find hardware for 10" brakes off a '66 CJ-5 (both came from the front axle of the same jeep). The springs don't match up in the ones I have (different lengths) and the wheel cylinders don't match (13/16 vs 1"). I even have spare hardware from two other backing plates and can't seem to match up springs that way. Feeling a bit dense and figured it'd all be easier/safer to get a set of new hardware.

I'd like to make them a matching set, does anyone have a part number or application that they know works? Maybe even for self adjusting hardware too?

Here's what I have:


I found a few threads on this from the past, but no part numbers. I guess the consensus is to stop what I'm doing and install 11" instead. I had intended on being patient and keeping my eye open for some 11" backing plates, but my current 9"ers are suddenly in desperate need of repair and I'm trying to make the best with what I have.

 

Go with the 11 inchers. You'll be pleased with the improvement in stopping power.

 

Aside from working better, parts for the 11" brakes are cheap and available everywhere. Backing plates from '60s F-100s will work, if you can make the backing plate center holes larger and drill the bolt circle to match the axle.

You can probably get used 10" parts by posting a WTB ad here. The fronts will have bigger cylinders than the rears, but different years could have different size cylinders. If the parts you need are not available from RockAuto, then try the Jeep specialty sellers.

 

In the picture, which return spring to shoe setup is correct: the left where the spring goes to a snag behind the friction material; or the right where the spring goes to a hole in the part of the shoe that is parallel to the backing plate?

Wow, RockAuto is fantastic. Thanks for showing me that. They do have the springs (OMIX-ADA Part # 1675013), but not the holddowns. This does make me realize I'm making this more complicated than it needs to be. I'm just going to replace the wheel cylinders (with 13/16") and reuse the springs I have. It may not end up as pretty as I made my 11" fronts, but that should make them safe and functionally equivalent to each other.

 

im keeping my 10" to untill i atleast get to drive it befor i decide to swap them. who knows how many people messed with your brakes befor you got it. mine had mixed left and right hardwhare on each corner and the backing plates on the wrong sides. napa has the cylinders, shoes, drums, hold down nails, adjusters ,and hold down clips. i had no luck finding the springs or the other self adjuster parts.

if you need a pic to help you put it together check post #5 in this thread.

Nice thread supertrooper. Thanks! Did you ever find out which spring was the leading vs trailing? Do you happen to remember the application you told the parts store to lookup the hardware (hold down nails, clips, and adjusters)?

 

i went on the napa website and entered the info for my jeep and those parts came up. if you go to napa have them look up the make under keiser jeep or somthing like that. when i took the other 3 drums apart the springs were the same length so i guess the first drum had one spring that was a little worn. it was less than 1/8" longer so i just put it on.
