How Important is it to Flush Your Brake Fluid

Brakes are an essential part of any vehicle, and they have to be kept in good working order. If you don’t flush your brake fluid regularly, your car will start to slow down as the fluid becomes contaminated with dust, grit, and other debris. Here’s how to flush your brake fluid:

What is brake fluid?

Brake fluid is a liquid that is used to stop your car. It is usually put in the car’s system through a pipe that goes to the brake pedal. Brake fluid helps the pads on the brake pads touch the road and makes it possible for you to stop your car.

How brake fluid works

Brake fluid is essential to braking effectiveness. When the brake pedal is pressed, hydraulic fluid is forced from the master cylinder and through the brake lines to the brakes. The fluid pushes on the brake drums to stop the vehicle.

If the brake fluid is low or dirty, it will not work as effectively and may even cause the brakes to lock up. It is important to flush the brake system every time you replace your brake pads or rotors in order to keep it working properly.

When is it time to replace brake fluid?

Brake fluid is an essential fluid in a car’s braking system. It helps to stop the car by providing a friction surface between the brake pad and the brake rotor. Brake fluid should be replaced every 3 to 5 years, depending on how much use the brakes get.
When it’s time to replace your brake fluid, here are some clues to help you determine if it’s time:
-The brakes feel spongy or soft when you press down on them.
-The brake pedal feels mushy or has a low resistance.
-The brake fluid smells sour or acidic.
-The vehicle makes a high-pitched squealing sound when you apply the brakes.

How to flush brake fluid

Storing brake fluid in a container can reduce the chance of a brake failure. The typical recommendation is to replace the brake fluid every 3 years, but if your car has been maintained regularly, you may only need to replace it every 6 months. Brake fluid should always be flushed and drained before service or an overhaul.


It’s important to flush your brake fluid every time you change the oil in your car, truck, or motorcycle. Brake fluid is a hydraulic fluid that helps stop your car or truck from skidding on a wet surface. By flushing the brake fluid, you are also cleaning out any debris that may have collected over time. If you don’t flush the brake fluid and debris accumulates, it can cause problems with braking performance and safety.
