The brake system in your car has been changed and improved upon for over a 100 years to finally bring us to the modern disc brake pads and rotor system you see now. This is by far the most efficient way to stop any fast moving vehicle and can be found being used on planes, trains and automobiles. Water has little effect on their capability and they seem to wear longer than any other system.
The Brake System
There is a lot involved in bringing your vehicle to a stop before you even get to the disc brake pads and rotors. Hydraulic brake fluid is used to initiate the process once you step on the brake pedal. Fluid is used because like steel, it won’t compress. Unlike steel it can work its way through twists and turns. The brake fluid is held inside of the master cylinder and when you step on the brake, a plunger pushes it into the brake lines. From there it will make its way through a series of brake lines until it reaches the disc brake pad and drum assembly.
The Brake Assembly
There are four major components that make up the brake assembly on your car. Each one has a significant role in bringing your vehicle to a halt.
How They Work
Despite all of the other parts involved, when it comes down to it is the disc brake pads and rotor that allow for your vehicle to slow down and then stop. As the caliper presses down, the disc brake pad is able to make physical contact with the spinning rotor. The friction that is created by the two elements is enough to bring it to a stop.
All of this heat and friction created while stopping your car takes it toll on the brake pads. Arguably the most often changed part on any vehicle, disc brake pads will wear down over time, necessitating that they be changed. Luckily they are equipped with a metal wear indicator that only protrudes onto the surface of the disc brake rotor once the meat of the pad has eroded away. When that metal piece makes contact with the rotor it will create an undeniable screech, alerting you to change the disc brake pads.
For optimal braking power, it is important that the metal rotor remain smooth. This too will develop scratches and grooves over time, especially with prolonged exposure to the wear indicator on the disc brake pad. The rotor may be machined one or two times to make it smooth again, but after that the metal will become too thin to withstand the heat that is generated when you apply the brakes. At this point, it will be necessary to change the rotor as well.
Brake Pad Material
The original disc brake pads were constructed of asbestos, which proved to be dangerous to the environment. Since then, we have been introduced to other materials that have been proven effective in braking capability.
Your driving habits and priorities will help you choose the type of brake pad you think is best for your vehicle.
