Why Is Water Contamination A Problem In Brake Fluid?
Water contamination in brake fluid is a common problem that can have serious consequences for your vehicle’s braking performance and safety.
But why is water in brake fluid such a big issue? In this section, we’ll explore how water contamination occurs, why it’s problematic for brake fluid, and the consequences of using water-contaminated brake fluid.
Firstly, how does water contamination occur in brake fluid? Over time, brake fluid can absorb moisture from the air through microscopic pores in rubber hoses and seals, leading to water contamination.
This is particularly true in humid or wet climates, where moisture levels are higher. Water can also enter the brake fluid if there is a leak in the brake system or if the fluid is not properly maintained.
So why is water in brake fluid such a problem? A brake fluid is a hydraulic fluid that transmits the force from the brake pedal to the brakes themselves. It’s designed to have a high boiling point to withstand the heat generated during braking.
When water enters the brake fluid, it reduces the boiling point and can cause the fluid to vaporize under heavy braking. This can lead to reduced braking performance, or even brake failure, in extreme cases.
In addition to reduced braking performance, using water-contaminated brake fluid can have other consequences. Water can cause corrosion in the brake system, leading to damage and potential failure of brake components.
It can also lead to increased wear on brake pads and rotors and can affect the function of anti-lock brake systems (ABS).
