Removing Rear Drum 2006 Aveo

OK I think the engineers between Daewoo and Chevy came up with the most frustrating assembly or just plain evil.

I know this question has been asked before (like a million times) and I have diligently read all of them. I can't get my rear drums off. <- please no comments from the peanut gallery [-X GRIN.

Here is a picture of my setup:
Attachment 7963

This is my assumption: I think there is a center cap concealing a the big 35mm nut. I can see two different kinds of metal there. I think there is faint grove between the two parts. So I tried pulling this part off. I used the big pliers to pull the cap. I tried a screwdriver between the two parts.

I tell you, it's not going. So I am asking for the sage advice of my fellow aveo owners who have done such.

HELP! whimper....:confused:

Just take out the two set screws if you just want the drum off. if you want to take off the drum with the hub take off the cap remove the center nut. Note: make sure the car is blocked good. Make sure the E-Brake is off to make sure it come off a little easier the pad be a little tight. You can use a two bolts if your not taking off the hub in the same tread size as the set screws help pop it off really tight. You tight them down even.

ALL most forgot it help to get the set screws out if you have impact driver. Not need less chances off stripped screws.

Thanks Mr. Pontiac! Done!

Here is a picture of impact drive and brake hub:

Using a screwdriver GENTLY pry between the hub and backing plate to start separating to two parts. Once loosen then use you hands to pull off the hub. And do make sure e-brake is off as Mr. Pontiac suggested.

Here is the brake assembly with the hub removed.

See it was easy, just having the right tool did the job.

Once I got the screws out the first time, I threw those away. I have never had any problems without them. Chevy used to use clips on the lugs to hold the drum (on older cars) instead of the screws. Growing up in Detroit, it was explained to me that they were just to hold the drums on along the assembly lines until the wheels were bolted on. (We always broke them off and didn't worry about them anymore.) I don't know if that was completely true or not, but I have not experienced any negative side effects by leaving the screws out. It does make it alot easier to get the drums off in the future. I take mine off every time I rotate the tires or switch out the snow boots and hose out all of the brake dust.

PS- I've found that when prying off the drums with a screw driver as shown above, it usually helps to take a rubber mallet and bump the drum with it while holding pressure on the screw driver. This helps to free the brake shoes from the drum if they are tight. Also it helps to coat with anti-seize or grease the surface area of the hub where it contacts the drum, especially around the center circle of the drum. This will help prevent the drum from becoming rusted on the hub and make it much easier to remove next time.

Nice Tip. Once I have everything apart and working on my rear trailing arm, I will post pics on the brake shoe replacement. I am going to have to brake (pun intended) the hydraulic lines to remove the sub-assemblies form the trailing arms.

please post the pics of the trailing arm work as I think I need to replace the trailing arm bushings as well.

No Kidding. I spent a frustrating day trying to get my arms off (opps) I meant to say my trailing arms. I started into it and man that's frustrating.

So remove those 2 screws and the drum will come off? I just want to paint them? and then when i am done just replace the screws? Do i have to be careful of over tightening or anything? or just tighten them back on until they are tight.

Mine didn't have Screws in it, it just came off after i took the wheel off and used a little man power to get it off because it was stuck, i used a rubber hammer to tap it off

Not that there a real bad to have them on, they do help keep the drum in oneplace so the pads wear more even. If you put a very light dab of Ant -sizes on the screws and just tighten them till snuggive them 1/8 turn that it. That way it's easy get them off thenext time. Without the screws there a chance it could be offset. When tighten up tires. Make chance the tire not straightwith the stub axel.

I have some pictures. I will post one below. I got everything back together. However I am not completely sure of all the details. I don't think the automatic adjuster is working right. The official shop manual sucks. There is no way to adjust the pads from the back with the hub on the assembly.

Here is one of the pictures I took of the adjuster.
Attachment 8077

Right now everything is super soft. I know I need to adjust it and I at lost on how to do it. My only solution is to do it manually with the hub off.

You can adjust the shoes out a little with the drum off. Just leave them just loose enough to still be able to slide the drums on. Then drive backwards sort of fast and pull the emergency brake. A few times of this and your rear brakes should be nice and tight. It works for me anyway.

PS - If you have installed new brakes shoes you will need to first lift the center console cover around the e-brake and back off all the way on the adjustment there. Do this before adjusting anything else.

Ah this is what I need to do. I give this a try. Awesome and thank you very much.

Spinning the star wheel on the brake adjuster doesn't move the brake shoes at all?

I can spin the star adjuster. I just can't get the auto-adjuster to work by driving backwards and applying the brake. Once I get home from work. I am going to get in the assembly and check everything again. I bleed the back brakes and I want to bleed the front brakes to cycle the old fluid and make sure there are no more bubbles. I had the brake lines open for a couple of weeks while I replaced the old axle beam.

I took the e-brake cover off and I found something interesting, the adjustment nut is already taken up all the way. Should I go ahead and still back it off?

Thank you for taking the time to do this write up xintersecty! :) It will be a great help when I replace mine.

I have never figured out why the screws are needed . Millions of American cars have been built with nothing holding the drums / rotors on but the wheels & lug nuts ?

And I have owned & worked on a few of them .

God bless
