Brake fluid is a vital part of the braking system in your car, it is important to regularly inspect and maintain it. This article will discuss brake fluid exchange vs flush, the difference and how to do a brake fluid exchange, and why you may want to do one instead of a flush.
Brake fluid exchange vs flush: Brake fluid exchange and flush are methods to clean the braking system. A brake fluid flush is when you drain all the old brake fluid from your car with the aim of flushing out any dirt or debris within the brake system. Brake fluid exchange, on the other hand, only replaces the old brake fluid with new.
Brake Fluid Exchange vs Flush Difference
Brake fluid is responsible for transferring the energy from the brake pedal to the brake pads and eventually stopping your car. The fluid in your brakes can become contaminated with moisture, which can cause it to boil and vaporize when you are braking.
This will reduce the efficiency of your brakes and may lead to other problems such as brake failure. The two ways to clean the brake system of your car which includes
- Brake fluid flush (brake bleeding).
- Brake fluid exchange.
The terms “flushing” and “replacing” are often used interchangeably to refer to taking out toilet water. However, these two words actually refer to different processes.
When carrying out brake flush, debris and dirt are forced out of the brake system by flushing with new hydraulic fluid. When carrying a brake fluid exchange, the entire fluid in the system is being entirely change.
What is Brake Fluid Flush
Brake flush is the act of totally removing all the old broken fluid and replacing it with a new one. Brake flush advisably is to be done during every oil change as it is as important as the oil change.
Brake flush (Brake bleed) is done by releasing all the old brake fluid into a container or draining through a vacuum. The old hydraulic fluid is then thrown away and new hydraulic fluid is poured into the fluid reservoir.
This process removes enough brake fluid to remove any air bubbles from the brake lines. This method, pumps fresh and dry fluid through the lines, replacing any contaminated or old fluids with fresh ones. The process takes about an hour but it’s not recommended for cars that have ABS since this type of system requires a different type of flush than a hydraulic one does.
The advantages of a brake flush are as follows:
- It removes any air bubbles that may have been created during the installation of new brake fluid.
- It removes any dirt or rust particles from the old or contaminated fluid.
- Removes any water from the old or contaminated fluid.
- It removes any corrosion from the old or contaminated fluid.
The disadvantages of a brake flush are as follows:
- There may be an increase in noise when you start driving after completing the process because air bubbles need to be compressed by the brakes for them to work properly again.
- It removes any dirt or rust particles from the new or clean fluid.
- It may increase the chance of low fluid levels if the brake was flushed before adding new fluid.
- It removes any protection that may have been left in the lines after bleeding.
- There may be a decrease in braking effectiveness when you start driving after completing the process because air bubbles need to be compressed by the brakes for them to work properly again.
What is Brake Fluid Exchange
The brake fluid exchange is a procedure that is done to replace the old brake fluid in the system with a new one. The flush, on the other hand, is done to remove any contaminants from the system.
Brake fluid exchanges are often recommended when there are no visible leaks or if there have been no recent changes in braking performance or pedal feel.
Replacing the old brake fluid with a new one is much faster than flushing but it’s important that only DOT 3 or DOT 4 fluids be used because they’re designed for use in vehicles equipped with ABS systems.
The benefits of brake fluid exchange:
- A fresh supply of new and clean fluid will be put into your car’s braking system.
- The old, dirty, contaminated, and oxidized fluids will be replaced by new ones which will improve the performance of your brakes by reducing the amount of heat generated during braking.
- It may also improve braking performance due to better wetting properties.
- Another advantage could also be that it reduces wear on other parts of your car’s braking system.
The cons:
- Exchanging brake fluids can be messy work as it requires removing an old reservoir cap and then replacing it with a new one.
- Extra parts such as tools, a new reservoir cap, bolts, etc. would have to be purchased in order to complete the job, which could add up to a significant cost.
- Brisk braking could lead to increased wear on other parts in your car’s braking system during brake fluid exchange.
Brake fluids such as DOT 3, DOT 4, and DOT 5.1 must meet certain specifications for use in automotive applications. There are several reasons why you should never even flush brake fluid in this category.
5 Common Causes of Low Brake Fluid Level
The brake fluid in your car is necessary for the braking system to function. If the brake fluid level is low, it can cause major problems with the braking system. Low brake fluid level is typically caused by leaks or spills, but even with regular use, some of the fluid will evaporate.
The 5 most common causes of low brake fluid levels are:
- Leaks.
- Driving conditions.
- Porous hoses.
- Evaporation.
- Driving habits.
- Underinflated tires.
With the help of the following information, you will learn about the five most common causes of low brake fluid levels. You can be aware of these issues and take preventive measures to avoid them.
Components of Hydraulic Brake System
Hydraulic brakes are a type of braking system that uses hydraulic fluid under pressure. This fluid is stored in a reservoir and is pumped to the brakes when they need to be activated.
The components of a hydraulic brake system include:
- Reservoir: It stores the hydraulic fluid under pressure and maintains the pressure required for smooth braking.
- Brake pedal: The brake pedal activates the release mechanism which sends the fluid from the reservoir to the brake cylinders.
- Brake cylinders: These are used to convert kinetic energy into potential energy by converting it into compressed air or liquid.
- Brake calipers: These are used for applying friction force on each wheel that rotates, thus slowing it down or stopping it.
Hydraulic brakes are used for vehicles that require a lot of stopping power. They are often found on heavy-duty trucks, buses, and tractors. Hydraulic brakes use hydraulic fluid to pressurize the brake calipers. This pressure is then transferred to the brake pads and slows the vehicle down.

What Happens if You Don’t Flush Your Brakes?
A lot could easily go wrong if you don’t change or flush your brakes from to time. The internal structure of the braking system relies a lot on the hydraulic fluid working the way they are supposed to.
When you do not flush your brake fluid, it can get corroded which further causes structural damage to your braking system, leading to costly repairs. Regular brake fluid service can prevent these deeper system issues from occurring.
Brake fluid exchange is recommended every 30,000 miles or 2 years, depending on your driving and braking patterns. If your brake fluid has become dirty or contaminated, it can change how your brake system operates.
How Does The Brakes Work
Good question, understanding how the car’s hydraulic braking system works is very important to all car owners and drivers. The brake fluid or hydraulic fluid is more like the engine, it makes sure the brake is functioning properly.
The fluid is more like the blood in the car’s hydraulic braking system, if there are no fluids there is not brake pressure. The brake system works with the principle of pressure and nothing more.
The car brake itself depends greatly on pressure from the brake pads to the fluid and then down to clamp down on the rotors. This action makes it possible to be able to slow down the spinning wheels or even stop them at some point.
If your car loses brake fluid, for you it means no efficient brakes or there are no brakes at all. Leaking brake fluid can be as dangerous as it gets, as no one can predict how a car driving at high speed will end without brakes.
Try as much as possible to give close attention to the braking system of your car. Make sure all the parts are always intact and there are no leaks whatsoever.
Is a Brake Fluid Flush Really Necessary?
Yes, brake fluid flush is very necessary from time to time, it is even recommended after every 50,000 miles. Brake fluid is a critical part of your car’s braking system and should be checked regularly.
The brake fluid should be flushed every time the vehicle undergoes major maintenance, which is usually about every two years.
The brake fluid flush removes all the dirt, debris, and corrosion that builds up over time. It also removes any moisture in the brake fluid that can cause it to freeze or boil during braking.
A flush will also remove any air bubbles that may have developed in the system over time. This ensures that all components of the braking system are operating at their optimum level and helps you get more from your brakes when you need them most.
How Much Does It Cost to Flush and Replace Brake Fluid?
The cost of replacing brake fluid varies depending on the type of car you drive, but it typically ranges from $3-$8 per liter. The cost can be higher if you need to purchase special tools to complete this task.
Brake fluid is a hydraulic fluid that is used in the braking system of a car to provide a constant supply of pressure to the brake calipers. It provides safety and prevents corrosion and overheating. Brake fluid also helps maintain the pedal feel for the driver. Brake fluid should be flushed every two years or 50,000 miles (whichever comes first).
Conclusion
The main advantage of brake fluid exchange is that it can prevent corrosion and rust in the braking system which can cause serious damage to the car. On the other hand, brake fluid exchange has some drawbacks too. For example, it takes time for this process to be completed and there are chances for leaks during this process which can lead to further damage to the car.
Brake flush on the contrast could leave some small debris and dirt in your car’s braking system. However, the process is a lot faster and cheaper than the exchange, you can opt-in for flush for the sake of short time maintenance until you have enough money for the change.
