United Glycol Brake Fluid DOT 3 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 by. high quaity glycol and glycol ether fluid, designed to function over wide temperature and humidity ranges. The high boiling point reduces the tendency of United Glycol Brake Fluid Dot 3 to vaporize at the elevated temperatures that can be reached during severe braking situations.United Glycol Brake Fluid DOT 3 is a highly stable product and has superior thermal stability that assures rapid transmission of pressure at sub-zero temperatures and prevents excessive leakage at elevated temperatures. It maintains this high level of chemical and thermal stability during long service and over wide ranges of temperature and humidity.- Compatibles with standard Dot 3 fluids- High boiling point- Prevents seal hardening or softening - Excellent lubricity
