How Often Do You Need Brake Fluid Flush

Brake fluid is a vital part of your car’s braking system, and it’s important to keep it at the right viscosity and level in order to prevent a brake failure. However, flushing your brake fluid regularly can help keep your car running smoothly and prevent potential problems down the line.

What is brake fluid?

Brake fluid is a fluid that is used to help stop a car. It is made of water, DOT 3 brake fluid, and corrosion inhibitors. Brake fluid helps to reduce the friction between the brake pads and the rotors.
How Often Do You Need Brake Fluid Flush?
To keep your brakes working properly, it is important to flush your brake fluid at least every two years or 6,000 miles. Failure to do so can cause your brakes to wear prematurely, and may even cause them to fail completely.
If you are unsure when your last brake fluid flush was, you can check by removing the cap and looking inside the reservoir. The color of the fluid should be a light yellow or clear. If the fluid is dark or thick, it means that you need to flush your brakes soon.

How brake fluid works

Brake fluid is a mixture of water and oil that helps to stop your car. When brake pads push against the discs, the friction creates heat. The heat vaporizes the water in the brake fluid, and the oil vaporizes from the flakes of metal that make up the brake pads.
The vaporized ingredients mix with air to create a mist. This mist sprays against the rotor and melts it. The liquid metal then drips onto the disc, stopping it from spinning.
Brake fluid should be flushed every 2 years or 25,000 miles, whichever comes first.

When should you flush your brakes?

How to flush your brakes

Brake fluid helps to keep your car from skidding and helps to stop your car quickly. When brake fluid is dirty or has low levels, it can cause your car to skid and stop slowly. Brake fluid should be flushed every two years or when the level falls below the minimum required level. This will help keep your brakes working properly and help you avoid any accidents.


Now that you have a better understanding of when and how brake fluid should be flushed, it’s time to figure out when you need to actually do it. Brake fluid should always be flushed every 3-5 years, but it really depends on the kind of driving you do and the condition of your brakes. In order to determine when flushing is necessary, you will first need to inspect the condition of your brakes. If they show any signs of wear or if there is any corrosion present, then it is time for a brake fluid flush.
