Brake Fluid Flush – Are they needed?

admin 2019-08-16

Period brake fluid flushes are one of the big debates in car maintenance. Some car manufacturers say it’s every two years while others may see its annual.  A good rule of thumb is to do it every 30,000 miles.

What is a Brake Fluid Flush?

The fluid absorbs the moisture in the air so it can quickly go bad.   The purpose of such flushes is to cleanse the brake fluid system.   This is done by removing all the fluid from the vehicle and then inject it with a whole new set of fluids.  A partial replacement of brake fluid due to air bubbles is called brake bleeding. 

How to Identify you Need a Flush?

Despite the controversy among manufacturers and mechanics, an easy sign of problems is when your car feels like it does not stop as well.  If you feel that you are having to push your hardest and not getting the results you expect.  Your car should should then be flushed soon thereafter.  You can also tell it’s going bad based on the color of the fluid.  

Contaminated brake fluid may cause brake issues and/or cause your brakes not to work as efficiently.  The bad fluid boils at a lower temperature.  Beyond the above, poor brake fluid will also impact other aspects of your vehicle.  Your hydraulic system could begin to rust.  Rubber portions in the valves in the cylinder and calipers could deteriorate.  Particles of it could go into the fluid.  These pieces could clog the braking system and permanently damage your vehicle.
