Brake Fluid

Since liquids can't be compressed, brake fluid transmits force to various parts of the braking system when you step on the brake pedal. Brake fluid must have a high boiling point because of the heat generated during braking and must not freeze during cold temperatures.

The Brake fluid level in the master cylinder should be checked at every oil change. The brake fluid reservoir is under the hood right in front of the steering wheel. Most cars today have a transparent reservoir so that you can see the level without opening the cover. The brake fluid level will drop slightly as the brake pads wear out. This is a normal condition and you shouldn't worry about it. If the level drops noticeably over a short period of time or goes down to about two thirds full, have your brakes checked as soon as possible. Never Put ANYTHING But Approved Brake Fluid in Your Brakes. Anything Else Can Cause Sudden Brake Failure! Keep the reservoir covered except for the amount of time you need to fill it and never leave a can of brake fluid uncovered. Brake fluid must maintain a very high boiling point. Exposure to air will cause the fluid to absorb moisture which will lower that boiling point.
