PLATINUM HD BRAKEFLUID is suitable for use in both disc and drum type brake systems, engineered for that critical link between the brake pedal and the brakes. It is formulated as a high-quality glycol and glycol either fluid, designed to function over wide temperature and humidity ranges. The high boiling point reduces the tendency of PLATINUM HD BRAKEFLUID to vaporize at the elevated temperatures that can be reached during severe braking situations.
