Brake Fluid Explained

Brake fluid is designed to function under high pressure and temperatures to stop the vehicle once you apply the brakes. When the brakes are applied, the pedal presses a piston inside of the brake calipers. The action increases the pressure inside the brake lines, which sends the fluid to the brake rotors. The rotors then squeeze the brake pads to contact the wheels and slow or stop the vehicle.

Brake fluids are either glycol or silicone-based. Glycol fluids are generally used in vehicles having anti-lock brake systems. Silicon-based fluids are designed for vehicles not having ABS. Additionally, brake fluids are rated numerically up to 5.1. The higher the number, the better the quality of the brake fluid. Over time, the fluid absorbs moisture and requires replacing. The vehicle's owner's manual typically advises as to how often to change the fluid. However, mechanics recommend replacing brake fluid every one or two years.
