DOT 4 brake fluid is a synthetic fluid, specially designed for use in brake and disc braking circuits. Its main features are as follows: - maximum stability at high temperatures - compatibility with all components of the braking system - excellent lubrication - Higher resistance to aging Its compliance with FMVSS 116 DOT 4 also ensures excellent product performance, even if it is polluted by water, due to the condensation of atmospheric humidity entering the circuit, especially through the rings. BRAKE FLUID DOT 4 has a high boiling point above 160 ° C and the boiling point at a condenser is 260 ° C. This guarantees a high degree of safety during use in all operating conditions. It is miscible with other brake fluids provided they meet the specifications.SPECIFICATIONS FMVSS 116 DOT 4 and DOT 3 SAE J 1703 D ISO 4925 Learn More
