Brake fluid is the hydraulic medium that transfers your foot pressure at the pedal into stopping force at each wheel. It sits in a closed system under pressure, moving through lines and into calipers or wheel cylinders where it pushes pistons that clamp brake pads or shoes against rotors or drums. Understanding what type of fluid your vehicle needs, how it degrades over time, and when to replace it keeps your braking system responsive and safe.
These articles cover what makes different brake fluids work differently—why DOT ratings matter, how moisture absorption affects performance, and what happens when you mix incompatible types. You'll learn how to check your fluid level and condition, why regular replacement matters even when your brakes feel fine, and how to recognize signs that your brake system needs attention.
