Benefits and un benefits of drilled disc

The main advantage is heat dissipation, because the brake disc has heat attenuation, which is fatal for ordinary high-performance vehicles; In addition, through the drilling of the brake disc, the under wheel quality is somewhat reduced, and the handling is still improved.
If it is an ordinary cast iron brake disc, it is good to draw lines and punch holes. Such discs are basically used in high-performance luxury cars, and perforated brake discs are used in most medium and high-grade sports cars. Punching is to dissipate heat and improve the heat decay resistance of the brake. Scribing is to quickly discharge the worn powder of the brake pad and improve the braking force. Both are basically to improve the braking performance.


Advantages of perforated and non perforated brake discs:
1. The perforated brake disc has better effect in rainy days. The perforated brake disc aims to better heat dissipation and reduce the impact of heat decay on the brake. The brake disc is divided into single-layer non perforated disc, single-layer perforated disc and double-layer hollow perforated disc;
2. Single layer non porous is generally used widely, which is used in most cars. The utility model has the advantages of low cost, small wear of the brake friction block and good rigidity. The disadvantage is poor heat dissipation

 

How to determine whether the brake disc needs to be replaced
During braking, the constant friction between the brake pad and the brake disc will also lead to the thinner and thinner thickness of the brake disc. According to different vehicle driving forms, the service life of front and rear brake discs is also different. In the past, taking driving as an example, the service cycle of the front disc is about 60000-80000 km and that of the rear disc is about 100000 km. Of course, this is also closely related to our driving habits and driving styles.

 

Observe the groove to determine whether the brake disc needs to be replaced
Generally, three small grooves are distributed on most brake discs, which are called wear indication marks. When the brake disc is worn so that no small groove can be seen, it indicates that its wear limit has been reached, and the brake disc needs to be replaced immediately.


Due to frequent friction, many small scratches on the brake disc are also normal. However, if the scratch is obviously deep and forms a shape similar to a small groove, we can touch the edge of the groove with our fingers. If the edge is sharp, it means that the groove is deep, then we should go to the 4S store to inquire whether the brake disc needs to be replaced.

 

If the brake indicator light on the instrument panel is on, it indicates that the vehicle's braking system is faulty. At this time, we should focus on checking whether the brake pads and brake discs are excessively worn. If there is no obvious excessive wear of brake pads and discs, the brake indicator light may be on due to insufficient brake oil or problems on the line. At this time, go to the 4S store for inspection and maintenance as soon as possible.
