The Importance of Brake Fluid

There are maintenance items on our cars that we sometimes forget.  For many of us, brake fluid can easily be one of them .  But first, allow us to explain what brake fluid does.

Brake fluid is fed through a series of lines to your brake calipers to help them clamp down on your rotors.  The fluid itself is pressurized by your brake booster, located in the engine bay.
When brake fluid is low, your braking will show.  A low amount of brake fluid will result in less pressure, and air in the system.  Air in your brake lines causes your pedal to feel soft and sluggish, which results in poor to very, very bad braking.

If your brake pedal feels soft, it likely means your fluid is low and/or air in the system.  Give the pedal some pumps till it feels firmer; many times this won’t solve the issue and you’ll need to service your brakes by “bleeding” the lines.  One way to tell is if the fluid in your reservoir is full but your brakes still feel soft, then it’s time to service them, which Parks Mazda can happily do for you in case you don't have the time or tools.
