Any motorist will tell you that brakes are one of the most important safety features in your car, followed by safety belts, air bags and positive juju. Brakes allow you to control your speed, and when you're in control of two tons of rolling steel you need to be able to stop safely.
All cars require regular maintenance in order to operate safely. A wise owner will come to recognize warning signs in their cars that may require a mechanic's expertise. One of the most common warning signs for brake trouble is when the driver is required to put more weight on the car's brake pedal in order to slow the vehicle. This is often a sign that the brake shoes in the car need to be refurbished or replaced.
What Brake Drums Do
Despite the fact that all motorists use their brakes constantly, very few people understand how their brakes work. A sensible car owner should educate themselves on the components of their automobile into order to stay informed when discussing issues with a dealer or a mechanic.
Drum brakes, as opposed to front tire disc brakes, are commonly found on the rear wheels of a car, where they provide braking control via pistons which press curved pieces of metal, called brake shoes, into the drum, slowing down the car. Unlike disc brakes, drum brakes generate more force in order to stop the car, and therefore have separate pistons, actuator arms and springs to help pull the brake shoes away from the drum once the brake pedal takes pressure off the piston.
Drum brakes can be repaired by amateur mechanics, but it's one of those things where you should really know what you're doing. If you have any doubts regarding your abilities, take your ride to a trusted professional mechanic. If you want to give auto maintenance a shot, there are many videos and guides available online to help you out. Tread carefully, though. Make sure you know what kind of braking system your car uses, and any special considerations you may need to make before starting repairs. Also, be careful to work in a well-ventilated area as drum brakes contain asbestos.
