Brake fluid is the lifeblood of automotive braking systems. This Mopar Performance brake fluid is approved to DaimlerChrysler standard MB 331.0 and/or DaimlerChrysler material standard MS-9971. It is certified to DOT 4 Plus standards, and maintains a minimum dry boiling point(ERBP) of 500Â° F (260Â° C) conforming to FMVSS 116 and ISO 4925. Brake fluid must maintain a very high boiling point, and exposure to air allows the fluid to absorb moisture, which lowers the boiling point. So when brake fluid falls below the factory recommended level, use Mopar brake fluid for Chrysler, Jeep, Dodge and Ram vehicles.
