Is It Possible to Flush Brake Fluid

Brake fluid is a vital component of your car’s braking system. When your brake pedal is pressed, the brake fluid helps slow down the car. Over time, brake fluid can become contaminated with dirt, bacteria, and other debris. If this material builds up in the brake fluid reservoir, it can cause the brakes to stop working properly.

What is Brake Fluid

Brake fluid is a type of fluid that is used to stop a car or truck. It is often blue in color and is used in the system that controls the brakes. Brake fluid can be flushed if it becomes contaminated or if it is low on fluid.

Types of Brake Fluid

There are a few types of brake fluid that can be used in cars. These include DOT 3, DOT 4, and EBC-2. DOT 3 is the most common type, and it’s what most cars use. DOT 4 is more resistant to corrosion, and EBC-2 is the newest type of brake fluid.

How to Flush Brake Fluid

Brake fluid is a valuable resource, but it can also become a nuisance if not properly flushed. Follow these steps to flush your brake system:

1) Park the car in a safe location with the emergency brake applied.

2) Shut off the engine and remove the key from the ignition.

3) Open the hood and locate the brake fluid reservoir. If there is more than one reservoir, locate the largest one.

4) Loosen the cap on the reservoir and pour enough brake fluid into the engine to cover the drain plug. Be sure to pour enough fluid so that when you close the cap, there is at least an inch of liquid above it.

5) Replace the cap and tighten it securely. Make sure that no air bubbles are present inside the reservoir.

6) Move the car as far away from any obstacles as possible and release the emergency brake.

The brake system should now be fully flushed.


It is possible to flush brake fluid, but it’s not recommended because it can cause damage to your car. Brake fluid contains a chemical that helps stop the wheels from skidding. If you flush the brake fluid, the chemical may no longer be effective and your car could potentially skid while braking. In addition, flushing brake fluid can contaminate your water supply with harmful chemicals.
