Brakes need brake fluid or hydraulic fluid to properly function. When the driver slams the brakes, the pressure within the brake lines will apply pressure to the rotors, enabling them to slow or stop the car.
Brake fluids are either made from glycol or silicon. For vehicles with anti-lock braking systems, fluids with glycol formulation are preferred. On the other hand, fluids with silicon formula are often used with older types of brakes. Nevertheless, it is not recommended to shift from one type of fluid to another, as it can mix with the remnants of the former fluid used and can wreak havoc on your car’s system.
Meanwhile, brake fluids can be prone to deterioration as they absorb moisture over time. In this case, drivers are often advised to drain and replace the old fluid. You can also refer to your owner’s manual as to the frequency of your brake fluid change.
