Brake fluid, also known as hydraulic fluid, is responsible for moving the various components of your vehicle’s braking system. The fluid operates under high temperatures and high pressure and, without it, your car or truck would not be able to stop when you push the brake pedal inside your vehicle. Aisin Brake fluid is a non-petroleum, automotive brake fluid designed for use in conventional hydraulic brake and clutch systems under moderate service conditions. It is non-compressible substance that lies within the brake lines, delivering the force created by your push on the brake pedal to each of the brake rotors on the four corners of your vehicle. Aisin Brake fluid is meets or exceeds U.S. Federal Motor Vehicle Safety Standard Specifications. Aisin Brake fluid Dot-3 and Dot-4 ensure good brake response under non-severe service conditions. It provides long fluid service life through good chemical stability and minimizes leakage by providing the correct seal swell and lubrication characteristics
