The fluid a driver chooses for their vehicle is just as important as any of the moving parts of the brakes. It is always best to choose the right option for your car when the need arises to pump those brakes. I'm Arwood, but the grandkids call me Big Papa. They act as the piping for the brake system and are responsible for transporting fluid from the master cylinder to the wheels. Over time, your brake calipers become worn down looking and can be an eyesore on a nicer vehicle.
There is not always a need to replace the calipers, but you do not want to drive around with this Skip to content. When to Dispose of Old Fluid Brake fluid is a great item to have on-hand, but if the container ends up needing to have its seal broken to be used in your car, then the clock starts ticking.
Types of Brake Fluid Not all brake fluids are made alike. DOT 3 Brake Fluid: DOT 3 is the most common type of brake fluid you will find in a typical vehicle that is used for conventional purposes.
Although it is interchangeable with other brake fluids with a higher boiling point, if your vehicle is used for things such as getting to and from work, leisurely driving, getting from point A to B, then your car will most likely use DOT 3 fluid for its braking system. DOT 4 Brake Fluid: Having a higher boiling point and providing a better fluid for high-performance, DOT 4 is typically utilized in performance vehicles that require driving on the more aggressive side.
It is considered the mid-graded boiling point in comparison to other brake fluids. If your vehicle is being used in a way that could be considered a step up from conventional driving, DOT 4 is an acceptable option. DOT 5. If you are doing a fair amount of aggressive driving, racing, dirt-track racing, off-roading, or drive a heavy-duty vehicle, then DOT 5. If this happens, pull over immediately and allow your brakes to cool. If you don't, you'll risk heating up the brake fluid, which will lead to brake failure.
If you smell anything strange or see any smoke, it's a sign that not only do you need new brake fluid, but there may be other damage as well. It's safe to say that across the board, you should change your brake fluid every 2 years. However, every car manufacturer provides a different recommendation.
Other car models, such as Toyota Camry, Ford Escape, and Hyundai Elantra don't call for a specific fluid-changing interval. Rather, they recommend periodical inspections and upkeep. Brake fluid lives in a sealed system and can last for years. However, moisture from outside air can work its way through the many parts of the brake system.
Moisture can also cause corrosion in the calipers, brake lines, master cylinders, and other components. However, replacing brake calipers, rusted brake lines, and other brake parts can run you several hundred dollars or more. And if you live in a high-humidity environment, don't ever wait more than 5 years to do so. Winter weather isn't ideal either as contaminants like salt can make its way into the brake fluid.
Attracting more moisture and boiling at higher temperatures on braking is the cause of brake failure. It really is specific to the manufacturer. It may be that a new vehicle requires a silicone-based fluid and therefore has a reduced requirement for flushing and refilling. Some manufacturers of glycol-based fluids also claim that special additives in their products make them lifetime fluids. It also removes every single drop of fluid from the system. Many brake fluid replacements include a visual brake check as well.
Brake fluid plays an important role in the braking system. Simply put, your brakes won't work without it. When you press the brake pedal, you depress a piston in the master cylinder which, with the help of brake fluid, pushes another piston out of the slave cylinders. This transfers immense force and pressure onto the brake pads, which then clamp onto your wheels and slow your car down.

It is 'hygroscopic' in nature a fancy way of saying 'absorbs moisture'. This means it 'goes bad' even when working normally. Due to the immense heat generated under braking, brake fluid has a high boiling point to keep it working effectively. As a liquid, you'll have strong braking ability - you won't if it is a gas. If the quality deteriorates and it absorbs too much water, the boiling point decreases. Which means your braking ability decreases as well.
This can cause leaks and other problems with your brakes. In some cases, your brake lines may start to corrode which can lead to a much more expensive repair. It's relatively easy to change your brake fluid at home, but you shouldn't. A sub-standard brake fluid replacement can affect the safety of your car, especially if you lose the ability to brake. Leave it to the professionals instead.
