Brake fluid transmits hydraulic force to various parts of the braking system when the brake pedal is pressed. The brake fluid in your vehicle is a serviceable item that needs to be replaced at intervals determined by the manufacturer.

The brake fluid should be flushed every second year or every 30,000 miles to prevent the brake system from failing. Manufacturers may specify particular types of brake fluid to be used in their engines; consult your owners manual for more information on the correct fluid to use.
