[ACE]

how the drums work?
basically 2 brake shoes( one is the trailing brake/parking brake and the other is the leading shoe)there on opposite sides/or a U shape behind the wheel hub, connected by spring and powered by the wheel cylinder.

and when to replace depends on your brake use personally, quick stops etc. Im 21,000 miles on my car and fine with the oem brake shoes for the drums, but the front rotors were replaced a 1000miles or so ago, and thats with dealing with warped rotors for a long time too. but if the rear's are squealing thats not a uncommon time to replace noise lol

Brake shoe -->> [ (wheel) ] <<--- Brake shoe

lol is it difficult ?

its not difficult...but if your noticing some brake fade....its mainly because the fronts are doing all the work and the rears need an adjustment....you might want to do an adjustment...its pretty easy...

you will need a mallet and a flat head screw dirver to adjust the pads

take the mallet and hit the outer edge of the drum with it until it loosens up and then just pull it off..

take your screw driver and you will see an andjusting screw that goes across both pads right below the brake cylinder..i forget which way to turn it...but its not hard...turn the adjuster...it has notches on it...like a mini gear...the tap holds the gear in place...so take your finger pull the tab up and turn the gear with your flat head...a few turn one way.
re install the drum and see if its loose or tighther...

if its too tight you wont be able to get the drum on...
the best way to check if your drum is adjusted properly is to make small adjustments and reinstall the drum and then put the wheel on and spin it...if it makes 1 to 1 1/2 turns...that is perfect...

make sure your e-brake is off while you are doing this...this will also adjust your e-brake...will make it engage sooner with less clicks.

as far as the squeaking goes...it could be the springs that hold it together that are squeaking...might need to lubricate the parts that make metal to metal contact..

hope this helps...

a good rule of thumb is you will replace your front brakes twice before you replace your drums under normal driving.

i replaced my rotors with slotted rotors and hawk pads at about 35k...and my front pads still have about 8/32nds of life....rears i recently adjusted...right now im sitting at almost 57k miles

brake drums=shit

 

[mrsilent13]

brake drums=shit

brake drums have better stopping power than disc...but less heat dissipation...and since no one really adjusts them...well they get lots of brake fade because the front brakes are the ones doing almost all the stopping...so the fronts over heat...so lesson here is...if you have drum brakes...keep them adjusted

so as long as they are adjusted....they work fine

i think just about everything's been covered here. another method of adjusting shoes is removing the rubber plug on the backing plate and adjusting with an actual drum brake adjuster tool. you can get your basic drum brake tools for about 15 bucks at pep boys. usually up is tighen. the adjuster will only move one way unless you release the auto adjuster which is attached to your parking brake, which is usually a quick solution to something like this. if you don't use your e brake at all, the drums will never adjust. if it's till not right, adjust it manually like i explained through the backing plate and spin the hub by the drum. give it a good shove and try to spin it. it should spinn free and smoothe, but come to a stop before a full rotation.

as for the squeaking, i could go on and on.

Most modern brake systems (even my shitty 8 valve 99 cavalier) have self adjusting drum brakes.

Drive in reverse, apply brakes firmly. there is a little star wheel in there, and since the torque on the shoes is opposite of what they would see under normal forward braking, they adjust to take in the wear.

Believe it or not, this helps most of the time. If it still squeaks, pull the drum off and take a look.

I like to wear surgical gloves when doing brake work because brake dust gets under your nails easy and is hard as **** to get out. Gotta impress the ladies.

Like Mike said, parking brake can also do the trick, just depends.
