The disc brake disc (disc) is divided into solid disc (single disc) and air duct disc (double disc). Solid disk is easy for us to understand, to put it bluntly, is solid. Vented Disc, as the name implies, has the effect of ventilation. From the appearance, it has many holes in the circumference leading to the center of the circle, called air channels. The car achieves the purpose of heat dissipation through the air convection in the air duct, and the heat dissipation effect is much better than that of solid type. Most cars are front drive, the front plate using frequency meter wear is large, so the use of the front duct plate, after the solid plate (single plate). Of course, there are both before and after the duct plate, but the manufacturing cost will not be too bad.
The first picture in this article is the punched scribing disc, its braking performance and heat dissipation have improved, but the brake pad has greater wear. DIY modified brake disc, friendly tips: 1. The material of the disc must be good enough, without too many defects that affect the strength, such as large pores, trams, and shrinkage is not allowed. 2. The spacing and size distribution of the holes, etc., because more than one hole is drilled, the strength of the area is weaker. If the disc breaks, the consequences are unimaginable. 3. Symmetrical distribution. If the balance of the disk is seriously damaged, in the process of driving on the spindle will have a certain impact. 3. It's hard work, so be careful. You'd better not do it without professional guidance.
The perforated and marked brake disc, also known as a "speed disc" or "change disc", is usually fitted to high performance vehicles, such as racing cars, sports cars or sports cars. With the rise of the domestic auto industry modification wind in recent years, there are a lot of car friends DIY, from a variety of ways to get punched and crossed brake disc and then change their own. Punching and crossing brake disc is a double-edged sword, his advantages and disadvantages are also coexist, but the brake disc will increase the wear of the brake pad, the brake disc material and processing requirements are relatively high. Many small companies posing as Europe, Taiwan, Japan and other manufacturers in the production of high imitation of the brake disc, a lot of players like DIY attention.
Brake disc is a very important part of the brake system, a good brake disc brake stability, no noise, no jitter. Many DIY players do not have certain professional knowledge do not replace the brake disc casually, because the original factory brake disc is tested by a lot of professional engineers, is fully able to withstand the brake force of their cars. Sometimes after the replacement of the punched and crossed brake disc, the braking effect is not necessarily better than the original ordinary disc effect. So when it comes to safety, the total parts also need you to be careful when refitting.
