How Often to Do Brake Fluid Flush

It’s no secret that brake fluid can sometimes smell bad. However, it’s important to remember that the smell doesn’t always mean that your brakes are in need of replacement. In this article, we’ll take a look at when you should actually do a brake fluid flush and why it’s important.

How Often to Do Brake Fluid Flush

Brake fluid flushes should be done every 5,000 miles or every two years, whichever comes first.

The reason for this is that brake fluid contains chemicals that can corrode the brake pads and cylinder. When you flush the system, the used fluid is replaced with new, fresh fluid and any contaminants are flushed away.

Benefits of a Brake Fluid Flush

A brake fluid flush is important to keep your brakes in top condition. Here are some benefits of doing a brake fluid flush regularly:
-It keeps your brakes working at their best.
-It helps to prevent corrosion and buildups that can cause your brakes to stop working correctly.
-It makes sure your brakes are cooling properly and stopping quickly.
-It helps to keep your discs and pads in good condition.

How to Do a Brake Fluid Flush

Performing a brake fluid flush is an effective way to maintain your car’s braking system and keep it in good condition. Flushing the system every time you do a brake service will ensure that all the old brake fluid is replaced with fresh, clean fluid. Follow these steps to do a brake fluid flush:

1. Check the level of brake fluid in the reservoir. If it’s low, add enough new fluid to bring it up to the correct level.
2. Disconnect the negative battery cable.
3. Open the hood and remove the cap on the master cylinder reservoir.
4. Select a size brake line fitting (1/2-inch or 3/4-inch) and insert it into the end of the master cylinder reservoir hose. CAUTION: Do not over-tighten the fitting!
5. Connect one end of a hose clamp to the fitting on the master cylinder reservoir, and connect the other end to a clean container filled with water or antifreeze. Gently twist both hoses until they’re secure and submerged in liquid. (CAUTION: The brake hoses can become very hot when they’re in contact with hot brake fluid.)

When Should You Expect the Benefit of a Brake Fluid Flush?

The answer to this question depends on your braking system and driving habits. If you rarely use the brakes, a brake fluid flush may not be necessary. However, if you frequently use the brakes, it’s important to flush the system regularly to ensure maximum braking performance.


There is no one answer to this question, as it depends on a variety of factors, including the make and model of your car, the amount and type of brake fluid you are using, and the condition of your brakes. However, generally speaking, you should do a brake fluid flush every 2-3 years or whenever your brakes feel “rough.” If you have any questions about how often to do a brake fluid flush, please don’t hesitate to contact our team at Car Parts Discount.
