Willys Jeep CJ-5 11 inch Drum Brakes Swap

Early CJ-5 11 inch Drum Brakes Swap



























(Parts List & Equipment List)
by Jason Wakefield, August 2009

I have read several article on the subject, which have all been helpful. But I noticed some gaps in the information, particularly the parts list and what equipment you might need. So I decided to write an article for my own sanity and maybe for someone else that may partake on this quest. I am glad I did the swap, and have no regrets. I think anyone wanting to drive their early CJ-5 around should consider upgrading the brakes.

Simple Explanation
To convert the original 9 inch drum brakes of of an early CJ-5 to 11 inch drum brakes from a later Jeep model. I have a 1960 CJ-5 and this should work with CJ5 through 1971, and some CJ-3B Models.

Parts List:
4 11 inch back plates & brake drums ( 1972-1976 Jeep CJ-5, 1967-1970 Jeep Wagoneer, Jeep Truck, you can also find after market parts on websites like 4wd.com)
(BTW – You can continue to use your original hubs, they fit with these brake drums)
2 Sets of 11 inch brake shoes
2 Hardware Kits for installing brake shoes (springs, pins, etc....)
2 Left Side self adjustment kits
2 Right Side self adjustment kits
4 Wheel Cylinders ( all 4 are different)
8 5/16 bolts (½ inch length) for mounting the wheel cylinders to the backplates
8 5/16 locking washers for mounting the wheel cylinders ( looks like a star)
8 Wheel Cylinder Links ( your 9 inch drums do not have these, but your 11 inch drums do)
4 Brake Shoe Retaining Washer ( Diamond Shape, attaches top of the backplate. Mine were already attached on the donor backplates.)
2 12 inch rubber brake hoses for the front.
2 30 inch 3/16 brake line ( rear brakes)
1 12 inch ¼ brake line (front left)
1 40-50 inch ¼ brake line (front right)
1 30 inch ¼ brake line (Master Cylinder, could be optional)
2 3/16 to ¼ brake line adapter
1 Rubber Rear Brake Hose (Looked fine on the outside, but mine was junk, best to replace)
2 inch long collar pins ( you need 2 new ones to replace the ones you pull out of the rear axle)
Brake Fluid


Where to find Parts
 These parts can be found almost everywhere, although some were harder to find that others.
For me, the break down was as follows:
Backplates, Drums ( donor parts from a Jeep Farm), Brake Shoes, Rubber Hoses, Wheel Cylinders, Hardware (4wd.com), Self Adjuster Kits (Auto Zone, can be bought at 4wd.com), Bolts & Washers ( Local Hardware Store), brake fluid, grease, brake lines, adapters (Local Auto Parts Stores), Wheel Cylinder Links ( Jeep Dealership)
Many of these parts took time and shipping to get to me. So don't run to the Auto Parts store hoping all of this is in stock, it probably won't be. The hardest part to find was the Cylinder Links. Let me explain.


How I found the Wheel Cylinder Links
When visiting a Jeep Dealership, surprise surprise, their computers are not exactly equipped to find vintage parts for your Jeep. It took some effort on my part, and the parts person to find the Cylinder Links. We look through diagrams of Wranglers, Wagoneers and finally found it by looking at XJ Cherokees from 1985. In my case, he happened to have 2 of them, and comparing with one that was left over from my backplates, we confirmed it was the same part.
So my advice here is simple. If you pick up donor backplates, do not immediately throw out the hardware and parts attached. You may need them as a reference. It was extremely helpful to have a Cylinder Link in my hand when looking for this part.
The Part Number at the Jeep Dealership was # J0048331


Left & Right Backplates, Which is Which?
When I picked up my backplates, 2 were left, and 2 were right, but which was which? It is very simple.
Looking at the photo, you can see a RECTANGULAR NOTCH at the bottom of the backplate, and if you notice, it is slightly off center. When looking at them, the NOTCH will be either slightly to the left or slightly to the right. The NOTCH is for the star adjuster on your brake drums.
Backplates with the NOTCH Slightly to the RIGHT (LEFT SIDE, DRIVER SIDE)
Backplates with the NOTCH Slightly to the LEFT (RIGHT SIDE, PASSENGER SIDE)
SIMPLE!




Brake Lines
This was one of the gaps in the information I mentioned at the beginning. It is not a big deal, brake lines are usually easy to come by. But I thought I would give a brief explanation of why you are buying new brake lines.
Rear brake lines are 3/16 in diameter, and connect directly into the wheel cylinders. On the old Wheel Cylinders, they go straight in, but the new wheel cylinders connect at a 45 degree angle. Not a big deal, but that means either bending the original lines or just installing new ones. I chose to install new ones.
The front lines are more complicated. The original lines are 3/16 lines, but that is a problem for the conversion. The 11 inch wheel cylinders and rubber hoses that come out connect to a ¼ inch brake line. So what do you do? Well obviously you need to connect ¼ brake lines, but then you get to the junction box on the front left fender and it is a 3/16 connection.
If you do not know what I am talking about, there is a junction box where the Master Cylinder Brake Line comes in from the top, and splits 3 ways. One line goes to the back axle, and the other 2 go to the front brake lines. But those 2 front lines are 3/16, and you need ¼ to connect. My solution, use adapters at the junction box to connect your ¼ lines into a 3/16 opening on the junction box.


OPTIONAL PARTS & EQUIPMENT LIST
2 1/16 Inch Spindle Nut Socket ( Highly recommended, for front axle)
Hub Puller ( For the rear axle, borrowed from Auto Zone, worked great!)
Basic Brake Tools
3ft (approx.) piece of wood with ¾ hole at the end (could be a 1x2, 1x4, nothing too big)

Punch, Hammer ( for getting bearings out, hammer is useful in get drums and hubs off)

4 Bearings for front hubs
2 Grease Covers for hub
New Studs & Lugs
Axle Grease


Spindle Nut Socket
Yes, people are able to get the bolt out with a chisel and hammer, but I get impatient. Having the right tool makes this job a snap. I found it at 4wd.com. For a few $$$, it seemed worth it.
Piece of Wood

So you have the Willys Jeep up on Jack Stands and you start yanking on one of the axles and it spins. And you find there is no way to get any grip. Solution => Attach a piece of wood to one of the studs on the other side of the Willys, and wedge it up in the fender so the hub can not move. Worked perfectly. Does not have to be 3 ft, measure to make sure, and use any old scrap wood. Worked great for me.

Removal of Rear Hubs

A Hub Puller was absolutely necessary, no way to get around this. BEWARE! CAUTION! When you build up the tension on that rear hub, it will explode of the axle. One flew 3 ft in the air, and the other over a foot. Stand to the side when you are turning the hub puller and hitting the hub with a hammer. This was very exciting, but could have been painful.

Front Bearings & Studs

You have them off and you can easily replace them. Why not? If you are going to restore, mine as well take care of this while it is off. The inner and outer bearings are the same, took 10 minutes to do, and looked great. It is also a good time to replace studs if they look bad and beat up. Again, it is easy to do and you have it off the Jeep.

Conclusion

If there are parts and equipment I failed to mention that others found necessary and useful, let me know. My goal was to create a list that would be a comprehensive as possible. I like having all my parts and equipment assembled before moving forward. Enjoy the Quest, it will be worth it!

Happy Anniversary! Year 2 begins with a Bang

I realized today, that this same day last year I picked up the first 2 chassis in Upstate NY. Since then it has been a lot of work. A 3rd chassis had been purchased which is now our main focus.

After 365 Days, we have a running Willys Jeep with working brakes. Doesn't sound like much, but if you consider where we were last year, it is some decent progress. I can only imagine what the next year will bring.

In the picture, the 1960 Willys Jeep CJ5 out of it's shelter for the 1st time in months. Enjoying a hot summer day. Glad we can finally drive it and stop.

Progress.

Sticky Widget X 2

The brakes are done, some adjustment is needed, but they are done.

But there are last 2 instances in the project that brought frustration. I call them Sticky Widgets.

1st Sticky Widget: Rear Rubber Hose

So late Friday Night, after everything was installed, we began bleeding the brakes. But there was a problem. The rears were not bleeding. Fronts fine, the rears, nothing. Frustrating.

After some investigation, it was determined that the rear rubber hose was to blame. Fortunately, I had ordered one, and once installed, we were able to bleed all the brakes.

2nd Sticky Widget: Studs

It is not actually their fault, but they would not "sit" properly in the hub. After several attempts, I called the Master Mechanic, the suggestion was made => Aluminum Foil. Wrap the studs with the foil. As silly as that sounds, it worked, and the last wheel was put on.

2 very frustrating events, but they were both overcome in the end. To say I am relieved is an understatement.

Brake Work Update

For almost the entire summer, this poor Jeep has been confined to the make shift garage in the backyard.

The reason was simple, no brakes, no fun. It has been on jack stands the entire time. Had to be, when you take apart the brakes, you need to remove the hubs. No hubs, no tires.

But there is a glimmer of hope for this old Willys. If all goes well this Friday, the brakes will be done. Installed, working. And if they are working, this Willys will hopefully be able to come out and play in a nearby field. We shall see. Stay tuned.......

The Quest

About 30 seconds into assembling the first drum brake, we came across our biggest surprise as far as parts. With the wheel cylinder already mounted on the backplate and the backplate attached to the axle, all we needed was a wheel cylinder link.

A wheel cylinder link is what is pictured on the right, and it is placed between the brake shoe and the wheel cylinder. For reasons I can not explain, it did not come with any of the hardware that was purchased and so far no one sells it locally at Auto Zone and Pep Boys.

I have 3 of them, as they were left over from the hardware that was left on the donor backplates.

So, I am on a quest to find 5 more of these wheel cylinder links. If you are doing the 11 inch brake drum swap, make sure you secure these parts! 9 inch drum brakes do not have wheel cylinder links, so you need to find them with your 11 inch drum brakes. We can not assemble any more brake hardware until I find more wheel cylinder links.

My first stop on the quest is the local Jeep dealership. Then maybe a junkyard, and then.........who knows?

Progress

The picture says it all. This picture was taken of the front left wheel, and as you can see, it has been reassembled. All it needs is a brake drum, some bolts, and a brake hose hooked up and it is ready to roll.

The hub has new bearings and new studs. We are setting aside the left turning lugs and studs. Nothing against them, but I am certain they will get torn off by an unaware mechanic with a pneumatic impact wrench.

1 down, 3 to go!

All it needs is a Master Cylinder.......

As a wise friend of mine said, if that is all in needed, he would have fixed himself. How true how true how true.........

I can tell you with certainty that the Willys Jeep has no brakes. And when I mean no brakes, I mean nothing. Other than a few brake lines running along the frame, there is nothing left to take off. Master cylinder, brake drums, back plates and all misc parts that make brakes work are either in the garbage or sitting on the floor of the work area. Quite literally, there is nothing left to remove.

That is good news, because from here on out, we will be rebuilding, instead of tearing down. The donor back plates are wirebrushed and painted and ready to be installed. Parts are being gathered and arriving daily. The brake drums are having the studs removed at a machine shop, so we can install brand new studs to attach to the wheels.

I am certain that as of this post, there will be more items to purchase, I already know I need some more studs. But all I can say is this, we are very close to rebuilding a brand new brake system for a Willys Jeep.

Innovation

So when working on brakes, and axles in general you have to figure out how to turn nuts and bolts while the axles are freely spinning. It can be a little annoying.

So in this picture, you see my solution. A wooden plank with a 3/4 hole in it to attach to a hub. It hits the fender and stops the rotation. Very simple, and does the trick.

With that solution, I was able to make great strides in the tear down process. Almost done with the tear down, and getting excited about the rebuild.

The most exciting part was pulling the rear hubs. They came off with a large bang and flew across the floor. Glad I knew to stand off to the side.

Comparison of Drums

Drew is demonstrating the size difference between 2 rear drums. The size and weight are significant, who thought 2 inches would make so much difference!

Anyhow, the bolt patterns on the back plate and studs match, so it looks like we have a fit. Can't wait to get this project done.

Wagoneer Brakes

So I have already mentioned we are doing a brake drum swap. We are converting the CJ-5 from 9 inch drum brakes to 11 inch drum brakes. A description of the conversion can be found here.

Anyhow, here are the donor parts. They came off a 1970's Jeep Wagoneer. They are back plates and brake drums. They are already turned, so we know they will work. So what needs to be done is to fix some of the stud bolts and sand blast the parts and maybe a little paint.

I am going to try and document this process, for my sanity and in case any one is reading.
