How to Flush Brake Fluid in Car

Brake fluid is a necessary part of any car. It helps to stop the car in an emergency, and it needs to be replaced regularly. If you don’t flush the brake fluid regularly, it can build up over time and cause problems. Here’s how to flush brake fluid in a car.

What is Brake Fluid?

Brake fluid is a special type of fluid that is used in cars to help stop the car. It is a liquid that is stored in a reservoir near the brake pedal. When you press the brake pedal, the fluid is squirted out and onto the brake pads. This stops the car.
Brake fluid can also be used to clean the brakes. When you replace your brake pads, you should also replace your brake fluid. Brake fluid can become dirty over time and can cause your brakes to work less effectively. Replacing your brake fluid will also ensure that your brakes are clean and ready to use

How to Flush Brake Fluid

If your car has a brake fluid leak, you will need to flush the system to fix the issue. Here is how to do it:

1. Park your car in a safe location.
2. Remove any debris or objects that may be in the way of the brake fluid lines.
3. Locate and unhook the brake fluid reservoir (if present).
4. Remove the brake fluid Reservoir Cap (usually a screw on type cap).
5. Place a container beneath the brake fluid line that feeds from the Reservoir Cap and allow the brake fluid to flow into the container until it is almost full.
6. Replace the Reservoir Cap and tighten securely.
7. Drive your car for at least 10 minutes after completing these steps in order to allow the new brake fluid to bleed into all of the system’s components.

What to do if Brake Fluid Is Not Coming Out when You Try to Flush It

If you’re having trouble getting your brake fluid to come out when you try to flush it, there are a few things you can do.

First, make sure the reservoir is full. Second, make sure your brake fluid pressure is high enough. Third, make sure the hose is connected to the right port on the car. Fourth, make sure the valve is open on the brake fluid tank. Fifth, make sure the clamps on the hose are tight. Sixth, try flushing the system with a stronger stream of brake fluid. Seventh, if all of these steps fail, call a mechanic.


Brake fluid can accumlate over time in a car, causing the brake pedal to feel mushy or even impossible to press. If you’re noticing this issue, there are a few things you can do to flush the brake fluid and restore braking power:

1) Park your car in an area with plenty of room to work. Open all the doors and let it sit for at least 10 minutes.
2) Remove any items that could block the brake lines (such as heavy objects).
3) Use a plunger or bucket to force fluid from the master cylinder into the reservoir. Be careful not to push too hard; if necessary, you can use a vacuum cleaner to help suction liquid out of the reservoir.
