Features Of Disc Brake Pads

In addition, the action mode of disc brake is similar to that of ordinary bicycles - a rubber brake disc connected to the wheel hoop interacts when braking until the wheel stops rotating.
The most important thing is that the disc brake can be easily combined with the ABS system, and can be used more on medium and high-end cars; The drum brake has lower cost, higher absolute braking force and is easier to brake at one foot! More used in the rear wheels of ordinary small cars, that is to say, the front disc and rear drum!
Difference between brake pad sensitivity and brake tightness
Disc brake pads (discs) are divided into ordinary disc and ventilated disc. The ordinary disk type is easy to understand. In short, it is solid. Vented Disc, as the name implies, has the effect of ventilation, which means that the centrifugal force generated by the car in the process of driving can make the air convection and achieve the purpose of heat dissipation, which is determined by the special structure of the disc. From the appearance, it has many holes on the circumference leading to the center of the circle. These holes are made by a special process (sloped&drilled), so the heat dissipation effect is much better than that of the ordinary disk type. Due to the relationship between manufacturing process and cost, the brake pads of front ventilation disc and rear ordinary disc are generally used in middle and high class cars. For example, Passat, Vento Golf 2.0, Corrado and other cars, some advanced cars use front and rear ventilation panels. Most economy cars use the front disc and rear drum brake pads (brake pads). The front disc used here is usually just a common disc rather than a ventilated disc. It is worth mentioning that the use of ventilated discs in front wheels is gradually replacing the use of solid discs.
