Performing your own rear brake drum service.

Most of the time people don't really pay attention to their rear drum brakes let alone do a rear drum brake service. It is all covered up with the cast iron drum so people do see a need to service it unless it is making some loud sound.
Well for me usually I would remove the drum and take a look, clean off the brake dust with brake cleaner, don't use compressed air or all that air borne dust will find its way into your lungs.
sand and remove the inner ridge that had built up on the drum, remove, clean and lube the brake adjusting mechanism, shoe to backing plate contact area, ensure the hand brake cable is free.

Tonight the drums was a bit hard to remove, it seems the shoes wore into the drum making a ridge. You can go from the back of the backing plate where there is a hole and you can close the adjusters to retract the shoes. I did that and still the drum was rusted on the hub, hitting with a hammer didn't do much too. so I used two bolt and screwed them in equalled and it pushes against the hub pulling the drum outwards, then pop it came out.

Did you put any copper grease on the backing plate/shoe area? Where is the hole to adjust the brake shoes widths? The star wheel looks like it is too far from the backing plate to be adjusted from the rear. Did you install oem brake shoes?
Were your brake drums over the max diameter?

I recently changed original linings on the wife's 04 Kia - almost 200k and they probably would have passed safety. weird - but all highway km

When I do drums, I try to do them outdoors, and wash everything with soapy water and hose it out. A lot of drum brakes still have old asbestos filled linings. I read a report recently that said asbestos brake linings were common in Canada until about 2004, and even linings labeled "asbestos-free" had up to 60% asbestos in the base compound.
I wonder if offshore parts coming in are checked for asbestos these days.

edit - uggh, guess it's worse than I thought

The brakes likely self adjust using the handbrake.

Way to end with making the drums look asinine.

Need more comments/descriptors for each photo. 1/5 for the DIY.

Also, why is everything on your car covered in some disgusting oily slime?

i didn't use copper grease but i used silicone brake lube on the shoe contact and backing plate contact points after i sanded off the rust. there is two holes on the backing plate that have a rubber plug but I don't adjust the brakes through the hole. Instead what I learnt from school is to adjust the shoes with a bit of drag after you put on the drum, not to the point where you cannot rotate the drum by hand. These are not OEM shoes but OE Beck/Arnley shoes for under 20 bucks. I didn't both to check if the the internal drum diameter was over the max. The car is a 1999 Civic Ex 2 door coupe, and the parts are very cheap, I got raybestos drums for 25 bucks each and about 1 hour of my time to get the rear brakes done and good for another 2-3 years. 20 years ago it would make economic sense to pay 10 dollars to have the drums machined on a brake lathe, but today it costs just as much to machine than to buy new drums.

Good thread. I didnt know you could work on drums yourself really, Ive only done myself the brakes that are discs style on the front.

It is more difficult to do the drums?

Not difficult. You just have to remember how it all goes back together.

John it is not more difficult, i find them a bit easier that discs once you get the drum off lol.
if you are new to drum brakes, firstly take a picture of the components before you remove them. :)
if you got any questions you can message me or start up a thread.

Replacing shoes/drums is rather a lot more challenging then replacing pads/rotors. If you have the right tools though, its just another thing to do.
You have to deal with about 3-4 springs in drum brakes, a variety of clips and wheel cylinders that can pop out their covers if pushed too hard upon and leak brake fluid.
I've done drums/shoes using pliers before and it was annoying as hell as the main spring can be a b1tch to go in/out. Bought myself a brake shoe plier tool for ~8$ to aid in removing/installing the springs and it makes life 1000 times easier.

A great video for first timers
