HI...I started to post this on my brake thread but thought I'd have more response with this post.
It is a brake component, I think. �I was looking up prices for M/C and noticed under the brake category,
there were Emergency Brake Shoes for sale.
I have the E.B. handle but the cable housing and wire is cut just inside the engine compartment.
Working on removing the M/C I noticed this (in picture) at rear of T.C.
Is this what is left of an Emergency Brake Drum assembly?
If it is, how can it be replaced?
Thanks

:o Wow. �There must be an impressive story behind that one. �Maybe someone was driving down the road with the parking brake engaged and let it heat up red hot then drove through a puddle and shattered it? �I'm going to add that to my list of wow pictures. �
Basically to replace it you'll disconnect the rear drive shaft remove the the bold on the rear yoke. �Depending on how stuck on the yoke is, you may need to use a puller to get it off.

That black drum is what you are missing most of. �The next thing I'd do is remove the 4 bolts holding the backing plate on and remove the entire emergency brake assembly. �From there I'd clean it up and figure out what you have left so you can make a shopping list of replacement parts. �Luckly for you, most of those are all available.
Here's a good link on all the parts, what it's supposed to look like etc. �I know its for a 3b but you get the idea.

I'd also be concerned about that rear yoke. �You'll probably want to replace it. �How's the transfercase sound? �I'd be a little worried about the rear bearing and shaft depending on how the emergency brake was busted up like that. �

NoCoWillys....That is what I thought it was....I'm glad that it can be repaired (lucky.)
As far as the T.C., it sounds fine at 45 mph but haven't looked at the inside of it.
I don't think I want to know what happened to it....just be another distraction.
The E. brake on and splash of cold water is believeable enough for me.
When I finish my regular brakes I'll address it next.
Thank you for your reply and link to, "what it should look like."
I'll just have to keep my fingers crossed that the T.C. bearing and shaft is unharmed.
-
So, the jagged metal is what is left of the brake drum?
-
Yep, exactly. �It looks like when it exploded it ripped off the shoes. The part behind it with the 4 bolts is the backing plate.
-
That must of been one heck of a noise...probably louder than a backfire! Seems like it would have
done collateral damage to other components of the under carriage. (haven't noticed any) Hmm...it's a wonder it
didn't come up through the tub floor too. Well the main thing is everything looks OK.
-
Ouch!! �That photo looks painful. �I feel for that Willys. �Good that it's in your hands now. �
Tim
Here is a photo of the backing plate and components as yours should look.
�(http://i1195.photobucket.com/albums/aa397/athawk11/Handbrakeassy.jpg)
-
Tim.....Thanks for the photo...mine is a long ways from looking like that.
I will have to locate all the parts...may take awhile but I just pray nothing else was damaged.
Right now, I'm removing my brake system and replacing it so I can take the CJ for numerous drives to find
out how everything is.
-
Well, we all have priorities. �Mine would match yours. �Get it on the road and drive the heck out of it. �
I spotted this stuff and thought about you.

Even though you're not in a rush, the backing plate with adjuster and the drum would be worth getting here. �That is, if the price stays low.
Good luck, and most of all, have fun.

Is it possible to have the drum turned on the EBRAKE to clean up scoring?
Tumbleweed
-
It should be possible to do but the scoring shouldn't be any real problem on an emergency brake. After all, it isn't like a wheel brake where you would get pulsing in the pedal. Mounting the drum on a brake lathe might be a little tricky but not impossible.
I would think for most of us just wire wheeling or using an abrasive disc on an angle grinder would be plenty...Get the grease and any paint off the working surface and clean the rest so it looks good and you will be fine.
-
Sounds great to me. I'll just clean her up and assemble. Thanks..........
-
I'm going to challenge the conventional thinking, cause thats what I do. I'm guessing that E-Brake is a bubba special. IMHO the e-brake probably needed repair, so bubba took the puller to it but did not know how to get it off. Broke the drum, so he hammered off the rest of it, removed the e-brake guts casue they were now in the way and decided to live without the e-brake until he sold it. IMHO just guessing.
But now its in the right hands. It'll get right.
-
I almost have to agree with you Gun.
I am fairly new to all of this, but I have never seen that kind of damage done to an E-brake. �
I suppose it could have gotten caught on a rock, got cracked and then fell off. Even then, I doubt you would have lost that much of the drum without someone hacking off the pieces.
Tim
-
Everybody...thanks for the reply's....Gunslinger....that is a realistic possibility and in that case the T/C and shaft
bearing should be fine! Tim...thanks for thinking of me and sending the link to E-bay.
Sounds like me and Tumbleweed will be at least two bidders on it. Bill...the wire brush approach sounds fine.
-
Bill...I was getting e-mail notifications when some one responded to a post but don't receive them anymore.
I have the box,"notification of replies on this topic," checked.
-
I will ask Dave about it, I noticed the same thing for some posts I had subscribed to.
-
Thanks Bill!

Hey athawk11, when I put my backing plate on this weekend all my holes alligned up to the rear spedo brg. cover. Did you just put 1 bolt in the plate? I wonder if mine is not correctly but then why would all 4 holes line up. Just wondering.........I believe there are 3 long bolts a short bolt (behind the backing plate) and then 1 threaded bolt holding the backing plate to the spedo gear brg. cap.
Or have I had 1 too many Shiner beerz... :)
-
Hey Tumbleweed,
My photo showing the one mounting bolt was just to hold the backing plate in position while it was posing for the picture. My TC had not been painted yet, so I didn't want to fully assemble the hand brake, just to take it back off.
All four bolts should align!!! ;)
Good eye, though.
Tim

I think, after many hours of trying to determine why my E-Brake is in the condition my posted picture shows it is,
the main brakes weren't operable so they, P.O., used the E-Brake for the primary braking system.
-
athawk11....The E-bay E-Brake Assembly had only one bidder. Thank you for directing me to it.

That's great... �(I'm assuming you were that 1 bidder.) �$25.00 is a real score for all that stuff. �I saw an adjuster listed by itself for $25.00. �I know the other brakes are...and should be your priority, but with a few more small items like springs, and some shoes, and your lower assembly is back in the game. �
Is your brake handle and cable still hanging around?
Tim
-
Tim...the brake handle is and the cable runs to inside the firewall where it has been severed. So there is nothing from just inside engine compartment
to where the E-Brake assembly connects at the rear ot T/C.
-
I've been waiting but the E-bay E-brake assembly hasn't arrived yet. The lining shoes, wheel cylinder and cable
housing and cable will need to be bought for it. I've been holding off on ordering the 11" brakes for the front until
they could be ordered all at one time with the E-Brake parts. Who knows, it might arrive today>
-
Hey dodjh,
Where are you getting your 11" brakes from? Just thought I would ask since I will be upgrading as well both back and front.
George
-
Hey Tumbleweed....Well the PO did the up grade to 11" but I will be buying the parts I need, shoes, wheel cylinders, ecentric bolts
from Walcks. My front drums are fine as well as the springs. According to Carl Walck, the conversion from 9" to 11" was done with
station wagon and pick up brake components. I have a 75 J10 and I noticed I had one (1) set of shoes in my extra parts box
and they look almost identical to whats on the cj3a. My 3a was an early production model, 270?? serial number and a lot of
parts on it are cj2a parts: Rear end is a Dana 41, has a split windshield and the Tub is cj2a dimensions. The Tub does have the
cj3a tool compartment. The serial number plate says it is a cj3a so I guess that would be the official name but I have to always
remember it could be a 2a part I'm looking for.
It might be worth checking around for brake parts for those vehicles and you might find a better deal since you will need the drums also.
I hope someone else who reads this might have some more concrete information to add.

Tumble, My 11 inch brakes are off of an early 70's cj5. They work great and have the self adjusters. I would think they would be quite easy to find and the installation was pretty straight forward. Bob W knows quite a bit about the conversion and maybe he will chime in.
