DOT 4 Break fluid

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. Moreover it avoiding the problems of vapor lock and brake fade.

Features & Benefits:


  • High wet and dry equilibrium reflux boiling point (ERBP) minimizes vapor 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 broking 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 component life.
  • Selected corrosion inhibitors protect aluminum, copper, zinc and tin-containing system components from corrosion, ensuring long lite.
  • Good compatibility with common seal materials used in broking system s minimizes fluid leakage and reduces component wear caused by inadequate lubrication, ensuring good broking performance.
  • Excellent thermal and oxidation stability properties prevent fluid breakdown and deposit formation, maximizing fluid life and performance.
  • Fully compatible with other broke fluids that meet the DOT 3 or DOT 4 specifications also compatible with DOT 5.1.

Application:


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
