Brake Fluid DOT 4

Brake & Clutch Fluid

BULWARK BRAKE FLUID DOT 4 is a premium quality glycol ether & borate ester-based fluid with advanced corrosion inhibitors recommended for use in brake systems specifically for modern braking systems with electronic control systems such combined with ABS, ASC and ESP/DSC. Its Low viscosity and higher boiling point provide better braking efficiency.



The brake fluid is hygroscopic and must be stored in tightly sealed containers. After removal of brake fluid, the containers must be closed immediately. BULWARK BRAKEFLUID DOT 4 has a shelf life of at least three years when stored in original closed, airtight containers at temperatures of maximum 40 °C.
