How many liters of brake fluid does a Volkswagen Polo need for one replacement?
2 Answers
Approximately one liter of brake fluid is needed for one replacement in a Volkswagen Polo. Reasons for replacing brake fluid: Failure to replace brake fluid over a long period can lead to its deterioration, which may cause the vehicle's braking system to malfunction, posing safety hazards. Therefore, it is necessary to replace the brake fluid regularly. Brake fluid is generally replaced every 2 years or around 60,000 kilometers. Proper brake fluid: Maintain cleanliness. When replacing brake fluid, ensure cleanliness. The brake fluid must be filtered to prevent fine impurities from entering the braking system, which could damage it. Prevent moisture. The container storing the brake fluid must be sealed to prevent moisture and steam from mixing in and lowering the boiling point. Any replaced or improperly stored brake fluid in unsealed containers should not be reused. Avoid mixing. Different types of brake fluid, due to their varying compositions, may cause chemical reactions when mixed, leading to turbidity, sedimentation, and clogging of the braking system, rendering it ineffective.
As a regular car owner who often does DIY maintenance, I've been driving a Volkswagen Polo for several years and am quite familiar with brake fluid replacement. Generally, one replacement requires 1 liter of brake fluid. Although the system capacity is about 0.6 liters, the process involves thoroughly flushing out the old fluid and lines, so preparing a full 1-liter bottle is more secure. Using DOT 4 specification fluid is most appropriate—don't skimp on this, as brake fluid absorbs moisture, which lowers its boiling point and can lead to failure during emergency braking. I've replaced it myself twice: first, using a pressure tank to drain the old fluid, then slowly adding new fluid to avoid air entering the system. Check it every two years or 40,000 kilometers to ensure braking safety and extend the vehicle's lifespan.
