Frequently Asked Questions

Q: When should I change my brake fluid?

Ans: Typically, you should change your fluid in every oil change. You should inspect your coolant level twice a year and change the brake fluid at least once a year.

Q: What’s the most basic difference between DOT 3 and DOT 4 brake fluid?

Ans: DOT 3 and DOT 4 brake fluids are distinguished by their boiling point. Both fluids are hygroscopic. But DOT 3 has a lower boiling point, so this type of brake fluid absorbs water more.

Q: What if I never change my brake fluid?

Ans: If you don’t change your brake fluid in a year or two, your car’s braking performance will decline. Your brake system will sustain moisture contamination and debris will build up. There’ll practically be no resistance against corrosion.

Q: How do I know that the brake fluid level is low?

Ans: Your stops will become rough and your padel will feel mushy. Also, the fluid will look shady, dirty, and discolored.
