Brake pads will produce a lot of heat due to friction during the working process, the following are several ways to cool the brake pads:
★ Natural cooling
Parking ventilation: this is the most common natural cooling method. When the vehicle stops moving, park the car in a well-ventilated place and let the surrounding air take away the heat of the brake pads. The hot air will naturally rise, and the cold air will be supplemented, thus realizing the distribution of heat. However, this way of cooling speed is relatively slow, especially in the high temperature environment or the vehicle after continuous high-intensity braking, it may take a long time to make the brake pads back to normal temperature.
★ auxiliary cooling (vehicle driving process)
The use of vehicle driving airflow: in vehicle driving, reasonable control of speed can be used to cool the brake pads airflow. Maintain the appropriate speed, so that the outside air can fully flow through the brake system. Generally speaking, the faster the speed, the greater the amount of air flowing through the brake components, and the better the cooling effect. Be careful, however, not to exceed the speed limit and to consider road conditions and traffic rules.
Reasonable use of gears and engine braking: In downhill and other road sections that require deceleration, make reasonable use of the engine's pulling effect to assist braking and reduce the frequency of brake use, thus avoiding excessive heating of the brake pads. For example, when going down a long slope, switch the gear to a lower gear, through the engine resistance to control the speed, so that the brake pads can have time to cool down, rather than always be in a high-intensity friction braking state.
★ special equipment to assist cooling (in high-performance vehicles or special application scenarios)
To install a brake ventilation kit: this is a more effective way of cooling. Brake ventilation kits include components such as ventilation ducts, the principle of which is to direct cold outside air to the brake area. These ducts, which usually extend from the front air intake of the vehicle to near the brakes, utilize the positive pressure generated by the vehicle's movement to force cool air around the brake pads and discs, taking heat directly away. This approach is more widely used in racing cars and some high-performance vehicles, and can significantly improve the cooling performance of the brake system under high workloads.
Use of cooling sprays: There are spray products on the market that are specifically designed for brake cooling. These sprays usually contain special cooling ingredients that, when sprayed on the surface of the brake components, quickly absorb heat and cool down the system. However, this is only a temporary emergency measure and the effect of the spray lasts for a limited period of time, and it is important to ensure that the spray product used does not adversely affect the performance and materials of the brake system.
