Every Chevrolet car, truck, van, crossover, and SUV is engineered with a world-class brake system that delivers stopping power to the wheels’ rotor to slow down or stop your vehicle as needed. The lifeblood of the Chevrolet brake system is Brake Fluid. Brake Fluid is considered a hydraulic liquid that transfers force from the master cylinder through a caliper piston that presses the brake pads into the rotor. The reason Brake FLuid is used in vehicles is that it will not compress and is perfect for transferring the force needed to slow down your vehicle. The limitation of brake fluid is its hygroscopic nature; it absorbs moisture over time and this reduces its boiling point over time. As brake fluid collects more water, the heat generated in the brake system can make the moisture evaporate and the fluid is then compressible. Water-contaminated brake fluid is not able to function properly and your brake system will not stop your vehicle at peak performance.
