What Is Brake Fluid?


Brake fluid is the most essential part of a hydraulic brake system. Without the fluid, none of your other brake components will successfully operate, thus compromising your safety. To learn more about what brake fluid is, what it does, and whether it goes bad, read on.

Brake fluid is simply a liquid solution used in today’s motor vehicles. It turns the pressure you apply onto your brake pedal into a series of events to effectively slow down and stop your car. It is important to note that there are different types of brake fluid with varying viscosities and heat resistance points. You should always refer to your owner’s manual for guidance on which type is right for your car.

On the other hand, brake fluid generally all looks the same. It is a transparent fluid with a yellow tint. And in some cases, it can be described as having a fishy smell. Aside from these characteristics, brake fluid is known for having a high boiling point. It needs to withstand the friction created by your brake pads. Otherwise, your brakes will become less effective.

Brake fluid moves through the brake lines and calipers to push the brake pads against the rotors to stop spinning your car’s wheels. It all happens in a matter of seconds, so it is quite amazing. This fluid gets reused instead of burning off like gasoline. Over time, the fluid will get dirty and go bad. In severe cases, brake fluid can also leak from the system.

Therefore, if you experience any of the following symptoms, please have your brake fluid checked:

  • Soft brake pedal
  • ABS warning light illuminated
  • Fluid leak under vehicle
  • Longer than normal brake distance
  • Overall loss in braking ability
