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. Over time, this 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. This should take a mechanic only a couple of hours to do.

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.

It is possible to bleed your brakes yourself. This replaces most of your brake fluid, but not all of it. Considering the reasonable cost of this service, unless you’re a racer who needs to bleed your brakes frequently it’s probably worth just having the shop do it.

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.
