Brake fluid is a hydraulic fluid used in a vehicle's braking system to transmit force from the brake pedal to the wheel brakes. Found in all passenger cars and commercial vehicles with hydraulic brakes, it's critical for safe and reliable stopping power. Brake fluid must withstand high temperatures without boiling, absorb moisture without corroding system components, and remain stable over a wide temperature range. Different vehicle manufacturers require specific fluid types - DOT 3, DOT 4, DOT 5.1, or specific OEM formulations - for optimal performance and compatibility. Examples in our assortment include Febi brake fluid for Volvo Trucks (MPN FEBI26746) and Mercedes-Benz Trucks (MPN FEBI26748), as well as general-purpose DOT fluids meeting industry standards.
