What is Brake Fluid?
A. Composition of Brake Fluid
Brake fluid is a vital component of a vehicle’s braking system. It is a hydraulic fluid that transfers the force applied to the brake pedal by the driver to the brake components located near the wheels. The most common type of brake fluid used in modern vehicles is glycol-based, consisting of a mixture of polyethylene glycol ethers and additives. These additives help enhance the fluid’s properties, such as lubrication and resistance to temperature changes.
B. Role of Brake Fluid in the Braking System
Brake fluid plays a crucial role in the proper functioning of the braking system. When the driver presses the brake pedal, the force is transmitted through the brake fluid, creating hydraulic pressure. This pressure is then amplified and transmitted to the brake calipers or wheel cylinders, where it forces the brake pads or shoes to press against the rotors or drums, resulting in the vehicle’s deceleration or stopping.
C. Types of Brake Fluid (DOT 3, DOT 4, DOT 5, etc.)
There are several types of brake fluid available, each with different formulations and properties. The most common types used in automotive applications are DOT 3, DOT 4, and DOT 5.1. DOT 3 brake fluid is widely used and has a lower boiling point compared to DOT 4 and DOT 5.1. DOT 4 brake fluid has a higher boiling point, making it suitable for high-performance vehicles or in situations where the braking system is exposed to high temperatures. DOT 5.1 brake fluid, similar to DOT 4, has a higher boiling point and is often used in vehicles with advanced braking systems.
It is crucial to use the recommended type of brake fluid for your vehicle as specified by the manufacturer. Mixing different types of brake fluid can have adverse effects on the performance and safety of the braking system.

Why is brake fluid flush necessary?
A. Brake fluid’s susceptibility to moisture absorption
Brake fluid is hygroscopic, meaning it attracts and absorbs moisture from the air. Over time, this moisture can enter the brake system through small leaks or through the natural process of moisture absorption. This is particularly problematic because water boils at a much lower temperature than brake fluid.
B. Negative effects of moisture on brake fluid
The presence of moisture in the brake fluid can lead to oxidation and corrosion within the brake system. This can cause various components, such as the master cylinder and calipers, to deteriorate over time. Furthermore, the moisture can lead to a phenomenon known as brake fluid vaporization. When the brakes are applied and the brake fluid heats up, the moisture within the fluid can turn into vapor, creating air bubbles in the brake lines. This trapped air can significantly reduce the effectiveness of the brakes, leading to decreased stopping power and increased stopping distances.
C. Implications of degraded brake fluid on brake performance
As brake fluid deteriorates and becomes contaminated with moisture, its overall performance decreases. The presence of moisture lowers the boiling point of the brake fluid, increasing the risk of brake fade during prolonged or heavy braking. Brake fade occurs when the brake fluid reaches its boiling point, causing vapor bubbles to form and reducing the hydraulic pressure in the brake system. This can result in a loss of braking power and an increased risk of accidents.
In addition, degraded brake fluid can also compromise the effectiveness of the anti-lock braking system (ABS) and traction control system (TCS). These systems rely on the quick and precise transmission of hydraulic pressure through the brake lines, which can be hindered by contaminated brake fluid. Consequently, the ABS and TCS may not function properly, compromising the vehicle’s stability and safety.
Regular brake fluid flushes are essential to maintain the integrity of the brake system and ensure optimal brake performance. By removing old, contaminated fluid and replacing it with fresh fluid, the risk of moisture-induced corrosion and brake fade is significantly reduced. Properly flushing the brake fluid at the recommended intervals will help maintain the safety and reliability of the braking system, providing peace of mind while driving.
