Pulling/removing Brakes Drums on CJ3a/CJ2a

[dodjh]

Hello....I have read and looked at many threads/posts about my CJ's brake drum removal process.

My Brake Drum is 11" and is a Century Brand. �So far I haven't been able to locate a slot
to remove a Star type (adjusting system) entry point or do I see anchor pins or ecentric bolts.

These are pictures of my drums...front and rear bottom.

If these were the type w/ anchor pins & ecentric bolts, how do you collapse the shoes if they have created a ridge

on the outer edge of the Drum?

The part that is the anchor pin, do you hold the pin with one wrench and turn the nut with another wrench?

Any help will be appreciated.

dodjh,
The brake drum you are showing looks odd, but I haven't seen an 11" brake conversion. �

Can you post a better picture of the back side of the backing plate? �The reason I ask is the original 9" brakes will have eccentric adjusters. �I'm not sure if the 11" conversion does.

On 9" brakes, Yes...you hold the pin with a small wrench (1/4" and 5/16") , then loosen the lock nut. �Once loose, you spin the eccentric/pin to loosen the shoe from the drum. �

The rear drums slide over a tapered drive shaft. �Once you remove the outer castle nut, you will almost always have to use a puller to get the drum off. �Especially if it hasn't been removed for a while.

The front drums have a combination of large spindle nuts and washers. �One of the washers will look bent and mangled. �This is normal, as it is designed to be bent over the edge of the nut, to essentially lock the nut into position.

These will have to be removed to get the front drums off.

Again, �This description is based on 9" brake. �I have no idea if I'm helping you, or confusing the issue.

Many 11" brake conversions use late CJ components, but from the photos it appears this conversion may have used the early Utility/Truck 11" brakes. These are set up, adjusted and serviced just like the early 9" CJ stuff.

athawk11...I found the pin and nut, one on each side of each front brake assembly.  Bob W is right, it must be from a early utility truck conversion.

I don't have locking hubs yet but do recognize the parts you photographed.   If the shoes wore a groove in the drum, how do you suppress them

enough to prevent them from hindering the drum removal?

[athawk11]

Once you loosen the lock nuts, you should be able to turn the eccentric bolts.  It's hard to explain, but you will 'FEEL' it go loose when you turn it.
 
The eccentric is oblong.  Much like a 'half an oval.'  When the long part of the oval is against the shoe, it will be tight.  when the short side of the oval is against the shoe, it will be loose.  When you feel it go loose, it backs off the shoe by 3/16 to 1/4".  You will need to loosen all points to achieve these measurements.

If a groove in the drum is deeper than that, you may be in trouble.  I doubt it will be, but if so,  you will have to get a puller and force the drum over the shoes.  With all the eccentrics loose, the shoes will have a lot of give.  In fact, the shoes will likely come off with the drum.  You may break a spring doing this, but that would be a small price to pay.

That sounds fairly easy....will try and get the fronts off tomorrow. I guess I've become confused after saturating myself with

all the different threads on Brakes.  I was just on the cj2a Forum reading about brake removal.  It seems the rears are tougher

than the fronts.  Well, they will be next

Thank you for all your help!

I think the 11" brakes that Charles has on his Jeep are the type that only have the "Eccentric" adjusters and not the "Anchor Pin" adjusters. On this type the bottom of the brake shoes are free to slide up and down on the lower anchor, eliminating the need for adjustment there. More photos would be necessary to know for sure.

rocketeer...your picture looks like mine but there isn't any anchor pins on the bottom.

Bob W...I believe you are right.

I will clean up plate better and post some more photographs.
