PN 840

BG DOT 4 Brake Fluid provides the ultimate high temperature protection and moisture resistance for all DOT 4 disc and drum brake systems.

Brake systems can produce pressure up to 2000 psi. This pressure, along with extreme heat from the friction of braking, cause brake fluid to break down. This compromised brake fluid will boil at a lower temperature leaving air pockets and condensation in the brake system. Water in the brake system causes a myriad of problems such as brake deposits and varnish buildup.

BG DOT 4 Brake Fluid is a professional-use premium brake fluid. It protects the brake system at any temperature, fights moisture providing excellent rust and corrosion protection in all brake components. Because of its exceptional dryness and heavy duty additives, it can be used to clean the entire brake system.
