There are still a few vehicles these days equipped with drum brakes. And if your car has one, don't be surprised to find a brake drum in the system instead of a rotor. Drum brakes are similar to disc brakes in function, although they work differently, almost opposite. While disc brakes work through the brake pads pulling in, the drum brakes work through the brake shoes pulling out, against the surface of the drum. When the shoes get in contact with the drum, friction is produced and the wheels stop spinning.
Brake drums are very strong components that do not easily break down. If anything happens to them at all, that would be wear and tear as they get in contact with the shoes during braking. And, that wear and tear is pretty normal. In many instances, all that a drum will need after a while would be resurfacing, which pertains to the smoothening of the drum's surface to keep its contact with the shoes even. Sometimes, it's actually the wearing of the shoes that causes intensive wearing on the drum. You'll notice this because of the presence of a squealing or grinding sound every time you brake. Replacement of the shoes and drum resurfacing can fix the problem.
However, remember that there's an ultimatum to this. Like your front and rear rotors, your front or rear brake drum also has a minimum thickness. When it gets below that, it should be replaced or it can easily overheat and compromise your braking ability. In this instance, the best course of action would be to get a replacement. You can do the replacement of the drum yourself, provided that you are well aware of the procedure involved. If you lack skills or are not familiar with this, then leave it to a professional. You can't take chances with the brakes-a little mistake could have grave consequences.
After you have replaced your brake drums with new ones, remember to observe the necessary maintenance and precautions to ensure that they will not wear out fast. Of course, keep all your other brake parts in proper condition. It is often the damage of the shoes that accelerate wear and tear on the drums, so be sure that the shoes are in good shape. Inspect them regularly to monitor the thickness of their friction material, and replace them when the said material has already thinned out.
It's also important that you get only a high-quality brake drum to ensure long-lasting efficiency and service.
