The Differences between Drum Brakes and Disc Brakes
It is undeniable that the more one knows about the functions of their vehicle, the better the choices will be when new cars acquired. Furthermore, there is a better understanding of what preventive maintenance should be done and when it ought to be scheduled. Brakes are the most vital safety feature of any vehicle. There are two kinds: disc brakes and drum brakes.
Functions of drum & disc brakes
A drum brake is a small round drum that has a set of shoes within it. The drum brake will rotate together with the wheel and when the brake pedal is applied, the shoes are pressed up against the sides of the drum and the wheel is slowed down. A disc brake consists of a disc shaped metal rotor that rotates within a wheel. When pressure is applied to the brake pedal, a calliper will squeeze the brake pads against the disc. This will slow the wheel down as more pressure is applied to the brake pedal, bringing the car to a stop.
Which brake to choose?
There is a qualitative distinction between the two and some of it revolves around friction. The disc brake dispels the heat more effectively. Brake fade occurs when the brakes begin to lose their efficacy and this can happen on steep downhills for the drum brake design. It takes longer for the disc brake achieve brake fade, and these perform better on steep descends. The drum brake has the possibility of accumulating water within during rain or driving through puddles. That can lead to the drum brakes not performing as well in wetter conditions.
It is possible that your car may have disc brakes in the front end with drum brakes dealing with the rear tires. The reason is pure economics. Because a car weight is going to shift with braking, over two thirds of the braking effort occurs in the front of the car. There is not quite the need to have disc brakes, which are more expensive than drum brakes, on all four wheels. The maintenance of a drum brake is also cheaper. The brake drum has an all-in-one design that is very easy to replace when repair work is needed. In fact, the brake shoes can be replaced in less than ten minutes when the drum has been taken off. This means that both parts and labour costs are dramatically reduced when a drum brake is on the car. The drum brake also gets the job done, and both types of brakes will bring the car to a stop.
What is important to keep in mind is that either brake system is going to bring the car to a stop; the disc brake just does it more efficiently. The cost consideration is something that a car owner may want to think about. Understanding that most of the braking work will be at the front of the car, a model of car that has front disc brakes and rear drum brakes conceivably has the best of all possible worlds. The drum brakes in behind are much easier to replace if necessary. The owner can concentrate maintenance efforts on the front brakes and not worry too much about the rear ones. Overall safety and efficiency may be something that the car owner is concerned about, particularly in looking at a family car. In these situations, the disc brake system on all four corners may be the best because it is the safest. It just is up to consumer which brake system, either a four disc brakes or a combination of the two types, is going to be what fits the need.
