What does brake oil do?

Brake fluid is a type of hydraulic fluid. Brake fluid runs through the brake lines that go to all four wheels of your vehicle. When you press down on the brake pedal, the brake fluid allows force to be applied to the brakes to allow your vehicle to slow down and stop. Brake fluid can break down over a period of time.

How often should you replace brake fluid?

Every four to five years

A good rule to follow is to have your mechanic check your brakes and brake fluid during every oil change. They'll be able to give you the best feedback on how your brakes are working and if they need new fluid. Most drivers find they need to change their brake fluid every four to five years.

How to check your vehicle’s brake fluid level?

You should check your brake fluid level every few months – don’t just rely on your dashboard warning lights to tell you when your level is low.
