Disc brakes, this braking method, demonstrate many advantages. Firstly, its excellent heat dissipation performance allows for better maintenance of braking performance during continuous braking compared to drum brakes, making it less prone to degradation or failure due to overheating. Secondly, the thermal expansion of the brake disc in the thickness direction is negligible, so the size change after heating will not significantly affect the stroke of the brake pedal. Furthermore, the disc brake system has an extremely fast response speed and can easily handle high-frequency braking actions, perfectly meeting the requirements of the ABS system. In addition, its braking force is balanced, without the frictional assistance of drum brakes, making the braking force of the left and right wheels more even. Meanwhile, excellent drainage performance also reduces the risk of brake performance degradation caused by water or sediment. Compared to drum brakes, disc brakes have a simpler structure, are easier to achieve automatic clearance adjustment, and are more convenient to maintain. In addition, many disc brakes are equipped with brake pad friction plate wear warning devices, which remind drivers to replace worn friction plates in a timely manner through sound, electronic, or tactile sensors.
