Does brake fluid really need changing?
Brake fluid is actually one of the most commonly overlooked fluids when it comes to car maintenance. One reason is that many workshops don't have the equipment needed to replace it properly. Another is that owners often simply don't realise it needs changing. The fact is, a VAG brake fluid change should be carried out every 2 years. That's the official service interval specified by the manufacturer. But why?
Brake fluid operates in a sealed system and could last for years if it weren't for one problem: moisture. Moisture from the surrounding air gradually finds its way into the brake fluid through various parts of the braking system. Once the fluid becomes contaminated, it can significantly affect braking performance. Old, contaminated brake fluid can make the brake pedal feel sluggish or spongy. It can contribute to poor heat management in the braking system and warped brake discs, as well as seized or worn brake callipers and ABS system faults. Moisture lowers the boiling point of brake fluid, which becomes particularly dangerous when the brakes are working hard. As temperatures rise, braking performance deteriorates and, in extreme circumstances, you could find yourself with no effective brakes at all. Over time, moisture also causes internal corrosion in the brake lines, callipers, master cylinder and other components.
A brake fluid change costs around BGN 100, including labour and materials. Replacing damaged braking system components, however, is considerably more expensive. And if your brakes fail at a critical moment, the consequences could be far more serious than any repair bill. Think about it. The choice is yours! When did you last have your brake fluid changed?
When should you have a VAG brake fluid change, and which type should you use?
As I mentioned earlier, brake fluid should be changed every 2 years or whenever the brake discs and pads are replaced. I recommend using genuine brake fluid.
