What Is Brake Fluid?

As an automotive technician, I often get asked about the properties and uses of brake fluid. Brake fluid is a type of hydraulic fluid that is used in a car’s hydraulic braking system. It is responsible for transmitting the force from the brake pedal to the brake system, which then applies pressure to the brake pads or shoes, ultimately bringing the vehicle to a stop.

Brake fluid is typically made up of a mixture of glycol and other additives that help to increase its boiling point, prevent corrosion, and maintain its viscosity over a wide range of temperatures. There are two main types of brake fluid: DOT 3 and DOT 4. DOT 3 is the most common type of brake fluid used in vehicles today, while DOT 4 is typically used in high-performance or heavy-duty vehicles.

The brake fluid reservoir, located under the hood of the car, is where the brake fluid is stored. It is important to check the brake fluid level regularly and top it up as needed to ensure that the brake system is functioning properly. It is also important to use the correct type of brake fluid as specified by the manufacturer, as using the wrong type of fluid can cause damage to the brake system.

In summary, brake fluid is a crucial component of a car’s braking system, responsible for transmitting the force from the brake pedal to the brake system. It is typically made up of glycol and other additives, with two main types available: DOT 3 and DOT 4. The brake fluid reservoir is where the brake fluid is stored, and it is important to check the fluid level regularly and use the correct type of fluid as specified by the manufacturer.
