The brake is used to slow the vehicle to a complete stop. When the driver depresses the brake pedal, force is transferred from the vehicle to the brake calipers and pads through fluid. Fluid enters and fills the slave cylinders at each wheel, forcing the pistons to extend to apply the brakes. The brakes transmit force to the tires through friction. Modern cars have a hydraulic brake system on all four wheels. There are two types of brakes; disc or drum brakes.

What is brake fluid?

Brake fluid is a type of hydraulic fluid used in the brakes and hydraulic clutches of automobiles. It is used to convert the force applied by the driver to the brake pedal into pressure applied to the brake system and to increase the braking force. Brake fluid is efficient and works because fluids are virtually incompressible. In addition, brake fluid lubricates all removable parts and prevents corrosion, allowing brake systems to last longer.

How often should you flush your brake fluid?

Brake fluid should be changed every two years to prevent brake failure and keep the boiling point at a safe level. Periodic flushing and refueling are necessary for vehicle maintenance.

Brake fluid must be flushed because the brake system is not indestructible. The rubber in the valves of the brake components wears out over time. These deposits end up in the brake fluid, or the fluid itself ages and wears out. Moisture can enter the brake system, which can lead to rust. Eventually, the rust flakes off and gets into the brake fluid. These flakes or deposits can cause brake fluid to appear brown, foamy, and cloudy. If not flushed, it will cause the braking system to become ineffective and reduce stopping power.
