Fluids: brake and cooling - interval, symptoms and service. Make an appointment in SpotMeUp.


Brake fluid absorbs moisture over time, which reduces its effectiveness at high temperatures. The coolant, in turn, is responsible for stable engine operating temperature and protection of the system against corrosion. These are things that "work" until they don't - and that's when it gets expensive.

The symptoms are not always obvious, which is why many drivers drive by heart or not at all. A good approach: follow the service recommendations and check the fluid condition during the inspection.

In SpotMeUp, select Automotive → Mechanics and service and fluid replacement service. Add in the comments: the year of the car, mileage and whether there has been any recent overheating/fluid loss.

Frequently asked questions:

  1. Does brake fluid really need to be replaced? Yes - it affects safety.

  2. How to know if the brake fluid is "bad"? A test with a humidity meter gives the answer.

  3. Is the coolant poured with “anything”? No - it's a good idea to use the right type.

  4. Is it normal to lose coolant? Small - sometimes, but permanent defects are worth diagnosing.

  5. Is engine overheating a serious matter? Yes - it's better to react immediately.

  6. How long does it take to change fluids? Depends on the car and range.

  7. Can I reschedule? Depends on the rules.

  8. How to join as a service? Add profile and services.
