The brake system is basically consisted of brake pads, brake rotors, brake caliper, and brake drums. These brake parts work together to transmit force to the wheels through friction. Simultaneous to the effect of braking to the tires and the road surface, the brake lights should also light up to facilitate road communication. On this matter, it is the brake pad sensor that takes the task. The brake pad sensor is usually a copper U-shaped clip that turns on the brake light. When this sensor goes down to the embedded wire of the brake pads, the brake light is activated. The brake pad sensors also count the rotation of the wheels for the precise timing of the brake warning. As the bright brake light is illuminates, you will finally be recognized by the other drivers. The brake lights are basically installed at the rear end of your vehicle. These lights often sit side by side with the other auto lights. In fact, the brake lights are the major auto lights included on the tail lights assembly that most modern vehicles have. Brake lights usually encounter problems like the brake lights never turn off.
