Brake Fluid Dot 4 12oz

Lucas Oil Brake Fluid DOT 4 in a 12oz bottle is a synthetic hydraulic brake fluid formulated to meet or exceed DOT 4 specifications for automotive brake systems. This product is essential maintenance inventory for vehicle operators, fleet managers, and technicians who require reliable brake fluid for routine service and emergency repairs across both road and off-road platforms.

DOT 4 brake fluid operates at a higher boiling point than DOT 3, making it suitable for high-performance braking applications and vehicles subjected to sustained thermal stress. The synthetic formulation resists moisture absorption better than conventional fluids, which is critical in humid or coastal environments where hygroscopic degradation can compromise brake system integrity over time. The 12oz single bottle format allows for targeted top-ups and system refills without excess inventory, reducing waste and storage burden in field kits or maintenance lockers.

This brake fluid addresses the needs of operators maintaining vehicles in tactical, law enforcement, and military contexts where brake system reliability is non-negotiable. Whether maintaining patrol vehicles, support transport, or personal duty vehicles, having verified DOT 4 fluid on hand eliminates downtime during scheduled maintenance or emergency brake service. Lucas Oil is a recognized formulator in automotive fluids and lubricants, positioning this product as a standard choice for maintenance-focused organizations.

DOT 4 fluid is compatible with the vast majority of modern vehicles and brake systems. Always verify compatibility with your specific vehicle's manufacturer specifications before use. Keep brake fluid in a cool, dry location away from moisture contamination, as DOT 4 is hygroscopic and will degrade if exposed to humidity over extended periods.
