Here are specific cases of the application of silicone oil in automotive braking systems, covering different types of vehicles, demonstrating the important role of silicone oil in ensuring braking performance:

High - performance Sports Cars

Take a certain Lamborghini model as an example. When this sports car is traveling at high speeds and performing frequent and intense braking, the braking system will endure extremely high temperatures and pressures. Traditional brake fluids may generate air resistance due to high temperatures, resulting in a decline in braking performance. Therefore, engineers selected silicone - based brake fluid. The high boiling point characteristic of silicone oil makes it less likely to vaporize at high temperatures, ensuring the stable transmission of braking pressure. In professional track tests, after continuous high - speed driving and frequent heavy braking, the vehicle equipped with silicone - based brake fluid still has a sensitive braking response, and the braking distance remains stable. This effectively avoids potential safety hazards caused by the degradation of brake fluid performance, providing reliable braking protection for drivers during high - speed driving.

High - end Luxury Cars

Some high - end models of Mercedes - Benz aim to enhance driving comfort and braking safety, and they apply silicone - related technologies in the braking system. These vehicles are equipped with advanced Electronic Stability Program (ESP) and Brake Assist Systems, which have extremely high requirements for the stability and accuracy of the brake fluid. The silicone - based brake fluid, with its excellent chemical stability and good fluidity, can maintain stable hydraulic transmission performance in different ambient temperatures. Even in cold weather or after long - distance high - speed driving, the braking system can still respond precisely to the driver's operations, providing a smooth and reliable braking experience for passengers in the vehicle.

Heavy - duty Trucks

In the field of heavy - load transportation, Volvo's heavy - duty trucks often need to perform braking operations under heavy - load conditions. The application of silicone oil in their braking systems is mainly reflected in the sealing of the brake calipers. The use of silicone - based sealing materials effectively improves the sealing performance of the brake calipers. Under harsh road conditions and frequent braking conditions, it can prevent brake fluid leakage for a long time, ensuring the reliability of the braking system. At the same time, the lubricating property of silicone oil can also reduce the wear of internal components of the brake calipers, extending their service life. According to actual operation data statistics, after the adoption of silicone - based sealing materials, the maintenance cycle of the brake calipers has been significantly extended, reducing the vehicle's operating costs.

New Energy Vehicles

Some Tesla models have strict requirements for the braking system due to their power output characteristics, with rapid starts and accelerations. In addition to the brake fluid, the piston movement of their brake calipers also applies silicone oil lubrication technology. Applying silicone oil lubricant between the piston and the caliper cylinder wall reduces the friction resistance of the piston movement, making the braking response more rapid and the action of the brake caliper more precise. In addition, the good antioxidant and chemical stability of silicone oil can adapt to the complex electrical environment in the braking system of new energy vehicles, ensuring the long - term stable operation of the braking system and safeguarding the safe driving of new energy vehicles.
