How often should the brake fluid in a Passat be changed?
1 Answers
The brake fluid in a Passat should be changed every 2 years or 50,000 kilometers, whichever comes first. Below is relevant information regarding brake fluid: 1. Automotive brake fluid is the liquid used in hydraulic braking systems. It must not undergo chemical reactions, must withstand high temperatures, and should not cause corrosion, softening, or swelling to metals and rubber. 2. Do not mix different types or brands of brake fluid. For braking systems with special requirements, use only the specified brand of brake fluid. Different brands and types of brake fluid have different formulations, and mixing them can reduce the performance of the brake fluid. 3. The volume of brake fluid changes with temperature. The brake fluid reservoir has a vent hole, which can allow moisture or impurities from the air to enter. Moisture absorbed or dissolved by the brake fluid lowers its boiling point. When a car is driven for long periods with frequent braking, the temperature of the braking system rises, which can lead to vapor lock in the brake lines. Compressed air can reduce braking force or even cause brake failure.
