How often is the most appropriate time to replace the brake disc?
The maximum wear limit of the brake disc is 2 mm, and the brake disc must be replaced after it is used to the limit. But in actual use, most car owners do not strictly implement this standard. The frequency of replacement should also be measured according to your own driving habits. The approximate measurement standards are as follows:

1. Look at the frequency of replacement of the brake pads. If the replacement frequency of the disc is very high, it is recommended to check the thickness of the brake disc. After all, if your disc charges faster, it means that you use a lot of brakes, so check the brake disc regularly.

2. Determined according to the wear condition: because in addition to the normal wear of the brake disc, there is also the wear caused by the quality of the brake pad or the brake disc and the foreign matter during normal use. If the brake disc is worn by the foreign matter, there are some relatively deep grooves, or If the disc surface is worn out (some places are thin, some places are thick), it is recommended to replace it, because this kind of wear difference will directly affect our safe driving.

There are oil type (using brake oil to provide pressure) and pneumatic type (pneumatic booster brake). Generally, pneumatic brakes are mostly used on large trucks and buses, and small passenger cars use oil type brake system!
The brake system is divided into disc brake and drum brake:
Drum brake is a traditional braking system. Its working principle can be vividly described by a coffee cup. The brake drum is like a coffee cup. When you put five fingers into a rotating coffee cup, your fingers are the brake pads. As long as you put one of your five fingers outward and rub the inner wall of the coffee cup, the coffee cup will stop rotating. The drum brake on the car is simply driven by the brake oil pump, The utility model is composed of a piston, a brake pad and a drum chamber. During braking, the high-pressure brake oil of the brake wheel cylinder pushes the piston to exert force on the two half moon shaped brake shoes to compress the inner wall of the drum and prevent the rotation of the brake drum by friction, so as to achieve the braking effect.
Similarly, the working principle of disc brake can be described as a disc. When you hold the rotating disc with your thumb and index finger, the disc will stop rotating. The disc brake on the car is composed of a brake oil pump, a brake disc connected to the wheel and a brake caliper on the disc. During braking, high-pressure brake oil pushes the piston in the caliper, Press the brake shoes against the brake disc to produce a braking effect.
Disc brake is also divided into ordinary disc brake and ventilated disc brake. Ventilation disc brake is to reserve a gap between two brake discs to make the air flow pass through the gap. Some ventilation discs also drill many circular ventilation holes on the disc surface, or cut ventilation slots or prefabricated rectangular ventilation holes on the disc surface. Ventilation disc brake uses air flow, and its cold and heat effect is better than ordinary disc brake.
Generally, large trucks and buses use drum brakes with pneumatic assistance, while small passenger cars use disc brakes with hydraulic assistance. In some medium and low-grade models, in order to save costs, the combination of front disc and rear drum is usually used!
The main advantage of disc brake is that it can brake quickly at high speed, the heat dissipation effect is better than drum brake, the braking efficiency is stable, and it is easy to install advanced electronic equipment such as ABS. The main advantage of drum brake is that the brake shoes are less worn, the cost is low, and it is easy to maintain. Because the absolute braking force of drum brake is much higher than that of disc brake, Therefore, it is widely used in rear wheel drive trucks.
