A brake fluid flush is a procedure that replaces the fluid in your vehicle’s braking system. It takes just an hour or two to complete. It’s possible to bleed the brakes yourself, but without a mechanic’s professional OBD2 scan tool you won’t be able to flush all of the fluid yourself. For that reason, as well as the reasonable cost of the service, it’s probably just as well to have a shop do it.

It’s possible to bleed brakes yourself, which will replace most of the fluid in your braking system. If you’re a track day enthusiast, it’s good to give them a quick bleed in between events to make sure you don’t lose braking performance from overheating fluid. We have an article detailing this procedure.

What Is a Brake Fluid Flush?

Your brakes operate on a hydraulic system. Pressing the brake pedal pushes fluid through lines to your calipers, which press the pads against your rotors to slow or stop your car. For a more detailed explanation of how your brakes work, see our article on the subject.

Over time, brake fluid absorbs moisture and gets dirty, which reduces its effectiveness. A brake fluid flush, also referred to as brake fluid change or brake fluid replacement, completely replaces the old fluid with fresh new fluid. 

What Happens If You Don’t Flush Your Brake Fluid?

Over time, the fluid can absorb moisture. It can also get dirty, which you can see if it’s turned brown instead of clear. If your brakes get too hot from constant braking down a steep hill, the fluid can boil, introducing gas into what is supposed to be an airtight system. 

Any of these conditions reduce the effectiveness of your brakes. You may have to push the pedal harder to get the desired braking performance. Eventually, you may not get as much braking power as you need. You won’t be able to stop as quickly as you should, which is a safety concern.

How Often to Flush Brake Fluid

Generally speaking, it’s best to do a brake fluid flush every two years or so. If you are particularly hard on your brakes, such as driving in mountainous territory or on a race track, you should do it every year. 

Check your owner’s manual and consult the maintenance schedule to see how often the manufacturer of your car recommends flushing the brake fluid. Some manufacturers have no recommended schedule. If that’s the case, follow the above guidelines.
