A disc brake consists of a brake disc connected to the wheel and a brake caliper on the edge of the disc. When the brakes are applied, the high-pressure brake fluid pushes the brake block to clamp the disc to produce the braking effect. The working principle of a disc brake can be described as a disc that stops spinning when you squeeze it with your thumb and forefinger.
Disc brakes are sometimes called disc brakes, and there are two types of disc brakes: regular disc brakes and ventilated disc brakes. Ventilated disc brakes have many round ventilation holes drilled into the disc surface, ventilation slots cut out, or prefabricated rectangular ventilation holes on the end face of the disc. Ventilated disc brakes use wind flow, and their cooling effect is better than that of ordinary disc brakes.
When the brake pedal is depressed, the piston in the brake master cylinder is pushed, and pressure is built up in the brake fluid circuit. The pressure is transmitted through the brake fluid to the piston of the brake sub-pump on the brake caliper. When the piston of the brake sub-pump is pressurized, it moves outward and pushes the brake pads to clamp the brake discs, causing the brake pads to rub against the discs to reduce the wheel speed and slow down or stop the car.
As the performance and speed of vehicles are increasing, disc brakes have become the mainstream of the current brake system in order to increase the stability of braking at high speeds. As the discs of disc brakes are exposed to the air, disc brakes have excellent heat dissipation. When the vehicle does emergency braking at high speed or brakes several times in a short period of time, the performance of the brakes is less likely to decline, allowing the vehicle to obtain a better braking effect to enhance the safety of the vehicle.
And because of the quick response of disc brakes and the ability to do high-frequency braking action, many vehicles use disc brakes with ABS systems as well as VSC, TCS, and other systems to meet the needs of such systems that need to move quickly.
The braking system is a very important safety system for global car manufacturers. Due to cost considerations, the braking system will not be configured too high, and the original brake discs are mostly made of ordinary cast iron, which is difficult to withstand instant high-temperature deformation when braking at high speed due to material and design problems, resulting in significant shaking, reduced braking power, and longer braking distance. When a sudden situation occurs, it is impossible to stop immediately, which is very likely to cause traffic accidents.
SANTA BRAKE high-performance brake discs, made of reinforced alloy materials, using a mature casting process, the braking surface using the auxiliary design of ventilation scribing, the high temperature generated by the brake pads can easily be carried away by airflow, can withstand high temperatures of more than 800 ℃, strong resistance to heat, with superb braking effect.
The main causes of brake shaking are as follows.
1, brake disc deformation, surface unevenness, uneven thickness, disc, and pad bite is not strict This problem is mainly caused by poor heat dissipation or bad material of the brake disc, the brake disc will be slightly deformed due to heat account cold shrinkage when the temperature changes; followed by natural wear deformation.
2. The following causes can also lead to brake shaking.
Worn steering rod ball head, aging suspension arm, worn ball head of lower swing arm, impacted wheel drums, severely worn tires, etc.
Solution.
1, shaking brake disc can be machine-smoothed to ensure its flatness this method will greatly reduce the service life of the brake disc and maintain the time can not be long.
2、Modify the original or professional manufacture of high-performance, heat dissipation effect of the brake discs, pads.
3、Brake discs should not be cleaned with water when it is hot, especially when you just get off the highway after a long journey. The sudden cold and heat will deform the brake disc, thus causing the steering wheel to shake when braking at high speed.
4, brake fluid should be replaced regularly, generally once every two years, if the brake fluid has been used for too long, there is deterioration, which will also have an impact on the brakes.
SANTA BRAKE perforated and scribed brake discs can completely solve the problem of shaking
The characteristics of the original brake discs with perforation and scribing
a: heat dissipation: with heat dissipation holes, increase the airflow on the surface of the disc, compared with the traditional original brake discs, its heat dissipation performance has been greatly improved, to avoid excessive heat build-up to affect the braking effect, effectively overcome the high-speed braking jitter phenomenon.
b: braking: the surface of the disc “drilling” and “scribing” will undoubtedly increase the roughness of the disc surface, thus greatly increasing the friction between the disc and the pad.
c: the effect of rain does not diminish: “drilling” and “scribing” brake discs in rainy days, due to the existence of holes and grooves, can effectively avoid the effect of water film lubrication, while the existence of the groove can throw the disc surface excess water out of the disc, more effective in preventing the weakening of the braking effect. The presence of the groove can throw the excess water out of the disc and prevent the braking effect from weakening.
