Can Anyone Help On These Brake Drum Size

I had a '67 V6 with swaged drums. Silly design when it comes time to change your brakes.

 

My '69 V6 has swaged drums too.

 

Andy,
The late swaged drums would have nothing to do with change of command because Kaiser was fully in charge from the 1953 exit of Willys Overlsnd through till the AMC buyout in March of 1970.
But yes it was likely a cost savings aimed to the civilian lineup.
Not sure what if anything was going on with military contracts back then.
Those late swaged drums would only be found on 4 cylinder CJ’s because the Dauntless versions always had 10” Wagner brakes which are not swaged drums

vtxtasy, I’m thinking your 67 cj either had an axle or an engine swap. You may be able to verify a change by way of gear ratio.

 

Fireball, you talking swaged 10” Wagners ?
My 10” Wagners use the countersunk screws to hold drums in position.
Mine were removed from a Dauntless cj.

 

Ken,

Both of the 67 CJ5s I have were standards with the four cylinder, though one had a V6 conversion at some point. The 66 Dauntless I have down at the barn does indeed have 10" Wagner drums. So looks like you are right on both counts.

I wasn't sure when Kaiser took over, as said earlier most of my experience with Jeeps has been with the earlier flat fender, including several CJ2As, one M38, and one CJ3B which was a junker that I bought for the drive train components then scrapped.

Howard,

Yes there were foreign contracts for military Jeeps up into the 70s, even military versions of the CJ3B, and the Navy actually bought a few CJs, but those were small potatoes compared to the prior US Government contracts.

 

Here is a pic of the front drum.

 

No, the Tuxedo Park got 10” Wagner brakes starting in ‘64. If I were rebuilding, I would be using at least 10” brakes.

Benebob,

That is the 9" Bendix brakes that would have been stock on your Jeep.

Dwins1,

Yes these are Marine contract axles. One set had Powr-Loc front and rear, one only in the rear.

 

From the visible backing plate, I’m guessing those are 9” brakes. The 10” don’t show that much edge behind the drum.
-Donny

 

Yes a 69 Daunltess with swaged 10 Wagner brakes. The fronts are not swaged but may or may not have been changed somewhere along the way:


But the rears are swaged (you can barely see the swage in this picture:


Definitely 10: Wagners:

 

Fortunately for Benebob those studs do not appear to be swaged. And yes, the backing plates for the later Bendix 9" are deeper than the 10" Wagners, and the earlier Lockheed 9". This deeper plate was intended to help keep debris out of the brakes.

A comment in the first post got my attention. "Amazed how easy things are coming off". You will change your mind about that when you get around to servicing the rear axle bearings, which is something you will need to do most likely.

The hubs do not come off easy unless they have been split by improper installation. When you get to that point start another thread on it, so we can help you avoid some common mistakes.

 

As a recent convert, if you drive your rig on the road more than 50% of the time/over 45MPH, I can't tout the 11" or disc brakes enough. The 9" on the road for any length of time are IMHO, dangerous.

 

I have converted most of the Jeeps I have owned that I intended to drive on the road to 11" brakes, and am considering disc brakes for the front on the Jeep I am building next.

Spence, did you use 11" drums on back and disc on front? I am thinking you told me that, but I talk to a lot of people about this stuff and may be confusing conversations.

 

It had 3.73 gears, T86, and V6. I don,t remember if they were 9" or 10". May still have them though buried somewhere.

 

11" drums on front as of now, the rears, 11" drums, when it cools down. The XJ swing pedal setup the PO installed definitely help a ton.

 

Vtxtasy, well apparently I don’t know what I’m talking about. According to your reply and Fireball’s the 10” Wagners were also swaged from the factory. Thanks for helping to set me straight.
The set I have was removed from a Dauntless CJ then shipped to me. I assumed they all had the drums bolted onto the hubs as is my current set-up on a F-134 Cj3B.

 

Okay got that left front side off today. Slid right off without the need of a puller. Everything actually looks darn good in there! I did place my orders for new mc, shoes, hard lines, rubber lines and wheel cylinders but did hear back from Kaiser that the hard brake lines are back ordered. I haven't found anyone else that has a set of preformed lines for the non S pipe 5. What would be the advantage of this set up rather than if possible installing the s pipe set up? I know that would require different soft lines would it also change the wheel cylinders or anything else? I'm not one who wants to deal with flaring and making my own lines. I'm perfectly content to stay with the 9" esp for now as I am just trying to get it up and running and usable. A full resto will be years off. Will only be used a few hundred miles or so on the road a year at best and I do have an old Royal Enfield Interceptor that takes about a 1/4 mile to stop from 100 with the front brake so I don't see the brakes being worse than that.

 

I always appreciate your wisdom. The problem is, we weren't there to know what was used.

 

Benebob, No real advantage either way as to how you configure the tubes and hoses. Either system works every bit as well as the other.
The earlier 9” Bendix brake system will require “S” tubes, different front tubes, different front hoses and different front wheel cylinders.
Also you will be missing the earlier hose guards that are attached to the king pin cap.
Rear brakes remained unchanged.
