The best way to exchange the brake fluid in your Volkswagen is to have it done by a certified technician. These technicians are trained to check the system for worn components, power flush it, and install factory-authorized brake fluid. While changing the fluid in your car is relatively simple, you should have it inspected by a professional technician to ensure that it’s the best product for your car.
DOT 4
If you’ve noticed that the brakes on your Volkswagen feel soft or weak, it may be time to replace the brake fluid. To do this, stop your vehicle on level ground and turn off the ignition. Next, release the hood release lever under the dashboard. Then, lift the hood and secure it with the hood rod. The brake fluid is located under the engine compartment.
For Volkswagen vehicles, the part number for DOT 4 brake fluid is B 000 750 M2. Some models of Volkswagen may also use DOT3 or DOT5 brake fluid. You must always check the specifications of aftermarket brake fluid before using it in your Volkswagen. If you don’t, your car could be at risk of a burn.
Glycol-based fluid
While both types of brake fluid are effective, there is a key difference between them. Glycol-based brake fluid is yellow and almost clear, while silicone-based brake fluid is purple. The former has a lower boiling point, and is typically used on older vehicles. Both types should be replaced every two years.
Brake fluid absorbs moisture from the atmosphere. As a result, it is less effective in braking, and can reduce the vehicle’s performance. The boiling point of brake fluid is reduced by as much as 75degC if it contains even 2% water. Glycol-based brake fluid is also hygroscopic, and can cause corrosion of painted surfaces.
The main disadvantage of glycol-ether-based brake fluid is its hygroscopicity, or the tendency to attract water. As a result, the fluid depreciates in value and effectiveness over time. Most drivers fail to notice this and wait too long before changing their fluid, resulting in bleeding brakes.
Water
You need to change your Volkswagen brake fluid regularly. The fluid in your car will break down over time, deteriorating the function of the brake system. It should be changed every two years or when it gets dark in color. It also helps you to protect the internal parts of your brake system. The brake fluid level in your Volkswagen should be between the MIN and MAX markings on the reservoir.
When you add brake fluid to your Volkswagen, make sure to check for leaks. This will help you determine the correct amount of brake fluid for your car. If the brake fluid is too low, air may get in the brake lines, causing your car to become unable to stop.
Vapor lock
If you have noticed that your Volkswagen brakes are not as effective as they once were, you may need to check the brake fluid in your car. Water in brake fluid can cause vapor lock, a condition that reduces the braking power and extends stopping distances. It can also lead to complete brake failure.
A new silicone brake fluid is designed to eliminate the risk of vapor lock in VW vehicles. It also has superior corrosion resistance and a low viscosity at cold temperatures. It is ideal for modern vehicles with stability control and anti-lock braking systems. It is also approved for use in all vehicles that require DOT 4 brake fluid.
It’s important to change the brake fluid in your VW in accordance with the manufacturer’s guidelines. Even a 2% moisture level in your VW brake fluid is considered excessive. Just 3% moisture can reduce the boiling point of the brake fluid by up to 50%.
