Classification and braking effect of brake disc
Disc brake disc is divided into solid disc (single disc) and air duct disc (double disc), perforated ventilation disc, scribed ventilation disc, floating ventilation disc and ceramic ventilation disc. Solid disks are easy for us to understand. Frankly, it is solid. As the name suggests, the air duct board has ventilation effect. From the appearance, it has many holes leading to the center of the circle on the circumference, which is called air duct. When the vehicle is running, the air passes through the air duct to achieve the purpose of heat dissipation, which is better than the solid heat dissipation effect.
Ventilated brake disc
The ventilated brake disc is ventilated and can play a better heat dissipation effect than the solid disc. The side of an ordinary ventilation disc is as flat as a solid disc. The ventilation holes can be seen in the longitudinal direction, and the structure inside is intricate and alternating, because it is necessary to ensure the heat flow and the rigidity of the brake disc at the same time.
Casting standard of brake disc
As for the casting standard of brake disc, the brake disc material on the Chinese market mainly adopts the Chinese gray cast iron 250 standard, referred to as HT250, which is equivalent to the American G3000 standard. Gray cast iron has good casting performance, vibration damping, wear resistance, good cutting performance and low notch sensitivity, and has been widely used in the automotive brake Market, The main constituent elements of gray cast iron are carbon C, silicon Si and manganese Mn. The important standard for testing brake discs is carbon content, which directly affects the friction coefficient. At present, the carbon content of ordinary brake discs on the market is about 3% .
Why does the brake disc rust and the solution
The brake disc is exposed to the sun and rain for a long time, and the working environment is poor. Especially if it is parked for a long time, it is easy to generate some rust on the surface, which is a normal phenomenon and there is no need to fight. We can remove rust by continuous braking during driving on the road of safe driving, because the disc brake is braked by the friction between the brake caliper and the brake pad, and the rust can be worn off under multiple braking. However, if the brake disc is seriously rusted, this method is not applicable. If forced braking, the brake pedal and steering wheel will feel obvious vibration. In this case, we need to go to the maintenance shop for treatment or replace the brake disc.
Daily maintenance method of brake disc
The brake disc will generate a lot of heat when braking, so don't wash the car immediately after braking. Turn off the engine to reduce the surface temperature of the brake disc and prevent the high-temperature brake disc from deforming and cracking due to thermal expansion and contraction in contact with cold water.
In addition, the best way to improve the service life of the brake disc is to maintain good driving habits and try to avoid sudden braking and sudden stop.
