How often should I change my brake fluid?


There are 2 common types of brake fluid used in cars today: DOT 3 and DOT 4. The DOT stands for Department of Transportation, the government organization that oversees standards for brake fluid. The fact that the DOT is involved in brake fluid standards indicates just how important this is for safe operation of your car.

Anyway, both DOT 3 and DOT 4 brake fluids can absorb water, which is why we recommend replacement every 2 years. This will ensure safe operation of the braking system at least as it concerns the brake fluid. If you are wondering what is the difference between the two types, DOT 4 has a higher boiling point. One thing to keep in mind is that you can switch from DOT 3 to DOT 4 if you like, but don’t switch down as the reduction in boiling point may affect the effective operation of your braking system. Feel free to contact us anytime if you have other questions about your braking system.
