The Importance of Brake Discs Brake Discs vs. Brake Drums
Disadvantages.
1.Because they do not have the automatic braking effect of drum brakes, the braking force of disc brakes is lower than that of drum brakes.
2. The friction area between the brake pads and the brake discs is smaller than that of drum brakes, resulting in less braking power. Vehicle braking is determined by a variety of factors, including the front and rear weight of the body, suspension characteristics, tyre performance, and road friction. But for the vehicle braking system, the importance of brake discs and calipers is unquestionable. Commercially available brake disc types and forms of a wide variety of currently available models of brake discs are mainly for the front and rear discs, as well as front discs and drums and other forms, and the rear wheels than the front wheels more stringent control to be embraced, because embraced will lead to loss of control of the vehicle, and therefore enhance the braking performance of the process of braking the rear wheels of the braking limitations are far greater than the front wheels. So we will find that many cars have larger front brake discs than rear brake discs, which is also no way of doing things.
Currently on the type of brake discs can be roughly divided into ventilated discs and solid discs, ventilated discs compared to solid discs, the biggest advantage is that its heat recession effect is better, and the front wheels need braking power to be significantly greater than that of the rear wheels, which is why the general vehicle are used in the front wheels with ventilated discs, the rear wheels with solid discs reason. For the brake disc material, the market is divided into metal and carbon ceramic material, although the carbon ceramic brake in the heat attenuation resistance and maintenance-free are better than metal brake discs, but often tens of thousands of dollars in costs or let its cost-effective greatly reduced.
