Why Change Your Brake Fluid?
Brake fluid lives in a sealed system and can survive for years, but moisture from the surrounding air can work its way in through hoses and other parts of the brake system. If your brake fluid has become dirty or contaminated, it can change how your brake system operates — brake pedal feel can be affected, as can heat dissipation in repeated stops. Water in the brake lines lowers the boiling point of the fluid, so stopping ability can diminish in hard stops as heat in the system increases. In addition, over time the moisture can cause internal corrosion in the brake lines, calipers, the master cylinder and other components.
You might be able to tell it’s time for a change by looking to see if the fluid is still fresh in the brake fluid reservoir, usually sitting on top of the master cylinder under the hood of your vehicle. Brake fluid is often light gold/brown in color but will darken with age, becoming murky from water contamination. A better way is to have it tested by a professional for moisture and see what they recommend.
Brake fluid is as vital to stopping a vehicle as engine oil is to keeping it going, but it doesn’t get as much attention as it deserves.
Brake Fluid Test
There is no need to guess whether it is time to change your brake fluid or not. Let us test your brake fluid boiling point to properly determine and make sure it is actually time to replace it.
