Your brakes are super important in keeping you safe. They are definitely one of the most important safety features on your car. You need to take care of your brakes and it may include adding brake fluid to your vehicle.
If your brakes are not stopping like it normally does once you press down on it, you need to take this seriously. Do not wait until the brake hits the floor and you are unable to stop!
Firstly, check to see if you need to top off your brake fluid to help keep the brakes usable. This is a great maintenance issue to know and will be dependent on the type of vehicle you drive. It varies. Some car makers may suggest flushing and replacing your brake fluid every two years or every 20,000 miles. Others might say that mileage does not play a factor and every two years is the staple of when to change your brake fluid.
The best answer is to check your vehicles' owner manual and base this necessity around your next service appointment.
