Winter is a time when every system in the car is under extra load, and the brakes are no exception. To avoid unpleasant situations on the road, you need to look after their proper operation, and the key element in this case is brake fluid. This article explains why in winter it is worth paying attention to the condition of the brake fluid, what factors affect its effectiveness, and when it should be changed.
Why does brake fluid condition matter in winter?
Brake fluid transfers force from the brake pedal to the braking mechanisms. If its properties change, braking efficiency drops, which is especially dangerous on slippery winter roads.
The main reasons to pay attention to brake fluid in winter are:
- Hygroscopicity. Brake fluid absorbs moisture from the air. At low temperatures the water can freeze, which leads to air bubbles and reduced brake effectiveness.
- Low temperatures. Winter puts extra load on the brake system, because the fluid must work correctly even in extreme frost. If the fluid has lost its properties, its viscosity rises, which slows force transfer.
- Corrosion risk. Moisture in the system can cause corrosion of metal brake components, which significantly shortens their service life.
How to tell that brake fluid needs changing?
The recommended brake-fluid change interval is every 2–3 years or according to the mileage specified by the vehicle manufacturer (usually 40,000–60,000 km). In winter, though, it is worth considering an earlier change, especially if you notice:
- A soft brake pedal. This may mean air bubbles in the system caused by excess moisture in the fluid.
- A longer braking distance. The car needs more time to stop, even though the brake pads are in good condition.
- Brake overheating. During intensive braking the system may lose effectiveness because of poor fluid condition.
- A change in fluid colour. If the fluid has become dark or cloudy, it has lost its properties.
How to change brake fluid correctly?
Changing brake fluid involves removing the old fluid, cleaning the system and filling it with new fluid. Here are the basic steps:
- Choosing the right fluid. Read the vehicle manufacturer’s recommendations carefully to select the correct type (e.g. DOT 3, DOT 4 or DOT 5.1).
- Preparing the system. Before the change, check the system for leaks and the condition of hoses and connections.
- Flushing the system. Removing the old fluid and residual moisture is a necessary step to ensure the new fluid works properly.
- Filling and bleeding. After adding the new fluid, bleed the system to remove any air that may have got in.
Although some drivers choose to do the change themselves, it is best to leave this process to professionals. At SerwisUA we offer a fast and skilled brake fluid change in Wrocław using modern equipment.
Winter tips for drivers
To keep the brake system in ideal condition in winter, follow a few simple rules:
- Check the fluid level regularly. You can do this yourself or during a scheduled technical inspection.
- Change before the frosts. If the last change was more than two years ago, it is better not to take the risk and to change the fluid before winter starts.
- Avoid sudden braking. This will reduce wear on brake-system components.
- Use professional services. If you suspect a fault, contact specialists.
