The effects of car brake fluid: You need to know

What is car brake fluid?

Brake fluid is an incompressible fluid used in a car's hydraulic brake system. When the driver presses the brake pedal, the force from the pedal is transmitted through the brake fluid to the mechanical components of the brake system, causing the vehicle to slow down or stop.

Thanks to its incompressible properties, brake fluid can transmit force accurately and stably. In addition, brake fluid also has a high boiling point and the ability to resist water absorption, helping to protect the braking system in many harsh conditions.

Car brake fluid greatly affects the safety of vehicle operation.

The effect of brake fluid on cars

One of the most important tasks of brake fluid is to transmit force from the brake pedal to other braking components in the vehicle, helping the braking process to take place smoothly and effectively. In addition, brake fluid also helps prevent corrosion of metal and non-metal parts in the braking system, lubricates and reduces friction between parts.

Not only that, brake fluid also plays an important role in maintaining the performance of the braking system even when the ambient temperature changes. With the right viscosity adjustment, brake fluid can work effectively in a variety of weather conditions, from high temperatures to humid environments. This helps to prevent oil breakdown and keep the braking system working stably.

Common types of brake fluid

In the current market, brake fluids are classified based on the FMVSS (Federal Motor Vehicle Safety Standards) safety standards with the codes DOT 3, DOT 4, DOT 5 and DOT 5.1. These types of brake fluids must meet the requirements of high boiling points to avoid evaporation when the brake system heats up during use.

Car brake fluid should be changed every 40,000 km or after 2-3 years.

DOT 3 and DOT 4 are the two most commonly used brake fluids in popular cars. They have good heat resistance and are affordable.

DOT 5 is a silicone-based brake fluid, commonly used in high-performance vehicles that require stability under severe operating conditions.

DOT 5.1 is an upgraded version of DOT 4, has better water absorption and anti-corrosion properties, and is widely used on high-end cars.

Brake fluid can be contaminated with moisture or other contaminants from the environment, especially through the fluid lines and vents in the fluid cup. This can reduce braking performance, leading to dangerous situations. When signs of poor braking are noticed, the driver should quickly take the vehicle to a garage to have the brake fluid checked and replaced.

In addition, allowing brake fluid to be contaminated with other substances such as engine oil can also cause damage to the brake system. Therefore, periodic inspection and timely replacement of brake fluid is necessary to ensure the safety and longevity of the vehicle's brake system.
