If you don't have your Brake Fluid changed as recommended by your vehicle manufacturer this will lead to Moisture Contamination in your brake reservoir where the Brake Fluid is stored.

As your brake fluid ages, it's also bound to be contaminated with 'Debris Buildup'. The various seals and hoses that make up your brake system can shed tiny amounts of rubber as they age. Moisture-laden brake fluid can also cause metal components to rust and corrode, resulting in rust particles finding themselves in your brake fluid.

When you don't change your brake fluid, your cars braking capabilities suffer greatly for it leading to Poor Braking Performance. In most cases, you can tell simply by pressing the brake pedal, if it feels incredibly spongy, then there's a good chance your brake fluid has nearly given up.

You might notice that it takes more effort and longer to bring your vehicle to a stop and in some cases, you may even have to pump your brakes just to build up enough pressure for a safe stop.
