You entrust your safety and the safety of your family to your car’s brakes. The brakes are a vital part of your car’s safety systems, and obviously stop your car when it needs to be stopped. You need to know that you can trust your brakes to work when you need them. While the casual driver may not realize it, there are actually a few different options when it comes to brakes: drums and discs. It can be beneficial to know about both.
Disc Brakes Vs Drum Brakes
Drum brakes are the earliest form of automobile brakes still in use. All forms of automobile brakes use friction to slow the wheels and the vehicle. Drum braking systems use shoes or pads that press against lining on the inside of the wheel to arrest the movement of the wheel. This form of braking has a natural self-applying quality, in which the shoes bite into the wheel without any additional application of force from the driver.
Drums are less expensive than discs, and are often used on economy vehicles. Lighter vehicles also make use of drums. However, there are a number of disadvantages to disc brakes, including:
Drum brakes are apt to overheat, which can cause the shoes to distort and cause vibration to the entire braking system.
Overheating can also cause brake fade. The heat from the braking can cause the shoes to lose their gripping abilities, meaning that the brakes may not be able to grip and braking may not occur.
Disc brakes present a significant advancement over drum brakes. Whereas drums press against the inner lining of the wheel to arrest the wheel’s movement, a disc brake’s pads are attached to a device called a brake caliper, which mechanically depresses on the wheels, stopping movement. Unlike drums, they are much better at dispersing heat, meaning that they are not as subject to the problem of brake fade. While brake fade may occur, it is far less likely in discs.
Discs are now more common than drums, as they provide superior braking power on larger vehicles. Smaller economy vehicles still commonly use drum brakes, as the weights involved make discs unnecessary. More and more hybrid cars are making use of the less-expensive drum brakes, as they make use of the energy generated from braking to charge the battery.
