How Does Moisture Affect Your Brakes?
Moisture in your brake fluid considerably lowers its boiling point, which can lead to brake fade during intense braking situations. As the temperature rises, vapor bubbles form, compromising braking performance and creating a spongy feel in the pedal. This decrease in efficiency not only affects your control but also poses safety risks, making regular maintenance essential.
Moisture Lowers Boiling Point
As brake fluid absorbs moisture from the environment, its boiling point decreases considerably, which can compromise your braking system’s performance. Here’s how moisture affects your brakes:
- Lowered Boiling Point: With just 3.7% water, the wet boiling point for DOT 4 fluid drops to 284°F (140°C) from 446°F (230°C).
- Increased Vulnerability: This reduction makes brake fluid more prone to boiling during high-pressure situations, such as hard braking.
- Compromised Brake Performance: Boiling moisture leads to vapor bubbles, resulting in a spongy brake pedal feel and diminished braking efficiency.
To maintain maximum boiling points and sustain your brake performance, regular maintenance and timely fluid flushing are essential.
Vapor Bubbles Compromise Performance
When brake fluid absorbs moisture, it creates a significant risk of vapor bubbles forming within the braking system. This vapor formation occurs because moisture lowers the boiling point of the brake fluid. During heavy braking, trapped moisture can boil, leading to vapor bubbles that compromise brake safety.
