Our motorized fellow citizens often come up with very original solutions that can really solve all kinds of problems. And that’s especially true when you consider that prices for repairs and spare parts have risen sharply. For example, drivers have recently started dipping an ordinary magnet into a tank with a brake. About how he can help, the portal “AvtoVzglyad” tells.
Usually, neodymium magnets are placed in the power steering or coolant reservoirs. They trap metal chips, which eventually show up in power steering or antifreeze. Such techniques are no longer new and many citizens use them successfully. But some “kulibins” went further and began to do the same with the braking system.
We note that this method is far from innovative. Automotive engineers started using it in the 90s. For example, ‘attractors’ can be found in the tanks of cars such as the Chrysler Voyager and Audi A6. But they are designed for something different.
Let’s take the German. It has a so-called reed switch (sealed magnetic contact). This is a device with two ferromagnets placed in a glass flask. The design is used to determine the liquid level. If the mechanism is faulty, it will begin to lie and the control buzzer will beep. Like a brake leak. And magnets crumble over time. Only the butt prevents debris from falling into the system. That’s why she needs to be watched.
But the goal, so to speak, of the folk method is to catch fine metal dust on a magnet, as if on a bait. After all, a lot of it accumulates in the system over the years. Especially if the car is used and not really tracked.
Let’s start with the fact that the brake itself is hygroscopic and actively absorbs moisture. Over time, the water content increases, fouling the system and causing corrosion to appear on the internal surfaces of the pipes. Nothing bad will happen at first. But if you start the process, the sewer reduces the effectiveness of slowing down the car, which is associated with an accident. And if there is too much sawdust, there is a risk that they will clog one of the thin tubes. The result is a brake failure.
Therefore, the magnet serves as a kind of indicator. If a very small layer of metal dust is visible on it, it is time to change the fluid. Even if it looks clean to the eye. This avoids serious problems, because the serviceability of the braking mechanisms is critical.
