What is the difference between the brakes of heavy trucks and ordinary cars?


Hello everyone, let's find out what is the difference between the spare parts on the brakes of ordinary cars and trucks.Brakes can be roughly divided into two ways. Most heavy trucks use drum brakes, while ordinary cars use disc brakes! Both drum brakes and disc brakes have their own advantages. Disc brakes have better heat dissipation and are relatively more sensitive. The advantage of drum brakes is that they are stronger when braking. In the process of driving, the weight of family cars is generally low, and the requirements for sensitivity are greater than the requirements for strength, so most family cars use disc brakes. As for those who choose to use drum brakes as the braking mechanism of family cars, in addition to Cost savings, I can't think of any other reason for the time being. For heavy-duty trucks, the weight itself is much higher than that of family cars, the weight of the towed goods is very considerable, and the inertia generated by the truck during driving will also be greater, and when the heavy-duty truck is traveling very fast, it may There is no way to brake directly. So if you want to brake heavy trucks, drum brakes are obviously more suitable than disc brakes.
