I was just curious about how drum brakes work. Can they be resurfaced like the rotors on disc brakes? Or, is it something totally different. I never had to deal with them so I don't know much about it. Any info is appreciated. Thanks.

 

they can be cleaned and adjusted :thumbup:

 

Drums can be resurfaced like rotors but the brake lathe they are turned on is totally different. There are 2 different types of designs of drum brakes, duo-servo and non-servo. They both work pretty much the same way except non-servo drums are non-energized. The difference between them are pretty much the location of the anchor pin. On duo-servo drums, it's located at the top. On non-servo drums it's located on the bottom. The pads in a drum brake are called shoes. The shoe on the left is called the primary shoe when you refer to duo-servo drums and the shoe on the right is called the secondary shoe. On non-servo drums the primary is called the leading shoe and the secondary shoe is called the trailing shoe. Between the primary/leading shoe and the secondary/trailing shoe is a star wheel adjuster. This is the mechanism that adjusts the drum brakes. There is a spring that holds down each shoe. These are called hold-down springs. In duo-servo drum brakes, the springs that go from the shoe to the anchor pin are called return springs. In non-servo drum brakes, the return springs are inbetween the shoes. Drums have a wheel cylinder which acts like a caliper for disc brakes. Basically the wheel cylinder pushes the shoes out against the drum, this is how drums work. In duo-servo drum brakes, when the primary shoe is pushed out, it is also forced to forced against the anchor pin to push out the shoe even harder. This is called self-energizing.

 

cool thanks!

 

Just go get a set of these and ditch the drums

 

how much where thos? and how much work was done to put thos in i was thinking of changing but i dont know how much work its going to take

 

It was not to hard you will need at least one other person to help.

I got them from www.modacar.com look under AEM rewar disr conversion kits.

I have more pics on my website at http://prime-fe1.lvcablemodem.com/aw...onversion.html

trust me if you do do it get the front big rotor kit to the stoping power now is great on my car.

 

Don't you need at least a 16" minimum wheel? And even then.. don't they recomend 17"? This is something I thought I read 3 years ago.. so... has it changed?

ya they recommend 17" wheels. and Of17 the prices are pretty expensive, I'm thinking in the 1k range but AEM might be cheaper. I know brembo and other fancy brands cost a lot of bones

 

I think AEM is $599 for the whole kit.
