Getting New Brake Fluid
Out of sheer necessity, the system that contains brake fluid tends to be extremely robust. The same is true of the transmission fluid system, for context. Some manufacturers recommend that you have your brake fluid exchanged every 20,000 miles, and some recommend going as long as 45,000 miles. Others don't even mention changing the brake fluid as if they expect it to last for the life of the vehicle. You may never need to exchange your brake fluid. However, you absolutely should have it checked- because things can always go wrong- and your brakes are not something you want to gamble on.
Does Brake Fluid Go Bad?
The sensible answer to this question is, "Yes, it can." The realistic answer is that it's unusual for brake fluid to go bad. If the brake fluid containment system is compromised, air and debris can get into the line. If this happens, it will degrade the ability of your brakes to bring you to a safe and reliable stop. If air gets into the line, your brakes may feel spongy or squishy. If that happens, you definitely need to get your vehicle in for a brake fluid inspection and likely a brake fluid exchange. If your fluid is leaking you may notice a gradual decline in braking performance. If debris makes its way into your brake fluid, it can clog the system.
Should I Get it Checked?
If you notice any of the symptoms mentioned above, you need to take your car or truck in for an inspection ASAP. If your automotive technician finds that your brake fluid has been contaminated, you will need to have it replaced, and your fluid contaminant repaired and resealed. It is wise to have your brake fluid and your entire brake system inspected at least every 50,000 miles. If your mechanic discovers a problem- then it can be remedied before it becomes a serious safety hazard.
