Brakes are obviously essential components in any motor vehicle. They are used to slow a car down. Without them it would be impossible to stop! For these reasons it’s important to consider how they work. This makes it easier to maintain them and react quickly if there are any malfunctions.
Brake Discs and Drums
Most modern cars will have a separate brake for each wheel. These will be operated by a hydraulic system. The two front wheels will often have braking systems that use discs to compress upon the wheel. These create enough friction to make the car stop. Drums do not compress the wheel but apply pressure from above in order to create the same result.
Most modern cars are installed with discs because they last a lot longer and slow down a car more safely. When braking harshly on drum brakes, there is a much higher risk of whiplash.
The reason why it’s most important to have disc brakes on the front wheels is because this is where most of the force is placed when stopping. When the brakes are slammed, all the force of momentum is shifted to the front of the car. That is why it is essential to have quality brake discs.
