Sinopec DOT 4 Synthetic Brake Fluid
Sinopec DOT 4 Synthetic Brake Fluid is formulated using a blend of synthetic glycol ether and borate ester with selected additives. It meets the requirements of the DOT 4 specification to give excellent brake and clutch performance, avoiding the problems of vapor lock and brake fade.
Sinopec DOT 4 Synthetic Brake Fluid is suitable for use in:
• Hydraulic disc, drum and anti-skid brakes and clutch systems of all passenger cars and commercial vehicles that require a DOT 4 or DOT 3 performance synthetic fluid.
Caution: do not use where a mineral oil-based fluid or a DOT 5 silicone-based fluid is required.
Features and benefits
High wet and dry equilibrium reflux boiling point (ERBP) minimises vapour formation on braking at high-speed or high-
load conditions and maintains the fluid’s hydraulic properties, thus ensuring good braking performance.
Borate ester in the formulation acts as a water scavenger and helps to maintain the ERBP during service, so
maintaining the quality of braking performance as the fluid ages.
Good fluidity, even at low temperatures, enables optimum braking performance.
A buffered alkaline pH protects iron and steel-containing system components from acidic corrosion, ensuring long
Selected corrosion inhibitors protect aluminium, copper, zinc and tin-containing system components from corrosion,
ensuring long life.
Good compatibility with common seal materials used in braking systems minimises fluid leakage and reduces
component wear caused by inadequate lubrication, ensuring good braking performance.
Excellent thermal and oxidation stability properties prevent fluid breakdown and deposit formation, maximising fluid life
Fully compatible with other brake fluids that meet the DOT 3 or DOT 4 specifications also compatible with DOT 5.1.
