Modern brake systems tend to be hydraulic<\/strong>. This is due to the fact that hydraulics itself allows you to use Pascal's law (we talked about it in detail here) and get a gain in strength, similar to the logic of the lever. In addition, hydraulic systems have a number of functional advantages regarding mechanics: the cable does not turn sour, braking is smoother, the movement is transmitted completely, the pads always return to their original position, there are no problems when working in the cold.<\/p>\n

All hydraulic systems use what is known as brake fluid.<\/strong> The liquid is precisely because, as we remember, our liquids are incompressible. This means that if a liquid is poured and moved, say, in a tube, then it will transfer<\/a> the movement, up to one millimeter, to the mechanism we need without shrinking.<\/p>\n

Unlike many other technical fluids,<\/p>\n

\"Brake<\/a><\/p>\n

Hydraulic brakes work on the principle of a hydraulic press, and it is the brake fluid that is design<\/a>ed to transfer power from the pedal to the brake pads.<\/p>\n

To perform its function well, the brake fluid must first meet three conditions.<\/p>\n

It The temperature in the brake system naturally increases with each braking.<\/p>\n

Driving in traffic or with the brake pedal constantly depressed can also put a lot of strain on the brake system. A good brake fluid should easily deal with these problems.<\/p>\n

\"Brake<\/a><\/p>\n

The greatest threat to the operation of the hydraulic system is the moment when the liquid filling it turns into a gas.<\/strong> Compressing gas is much easier. The same thing happens in the braking system.<\/p>\n

If the Brake would work with much less force or even refuse to obey.<\/p>\n

This situation is fortunately quite rare. But only if the brake system of the car (or other car) is filled with fluid with the correct parameters.<\/strong> In addition, it is replaced in accordance with the recommendations. That is why it is extremely important to follow the specification when choosing a fluid.<\/p>\n

With time. Although the brake system may appear to be sealed, the fluid itself is usually highly hygroscopic. Therefore, a small gap and air access is enough for the liquid to begin to draw moisture from the environment<\/strong>. This process is very difficult to prevent, and the consequences can be serious – the admixture of water significantly reduces the boiling point of the liquid. Well, if the brakes boil, we already know what this can lead to.<\/p>\n

The brake fluid specification includes test data. In the characteristics of each fluid option, you can find<\/p>\n

The first of these values \u200b\u200bcorresponds to the properties of the liquid before the first use, hermetically sealed in a sealed package, the second to the likely parameters after two years of operation, when the water content<\/a> will already be about 3.7%.<\/p>\n

The brand and grade of brake fluid we are dealing with can be identified by the grade assigned to it by the US Department of Transportation (DOT).<\/strong><\/p>\n

The cheapest fluids on the market are in the DOT-3 category.<\/p>\n

\"Brake<\/a><\/p>\n

Better quality liquids<\/p>\n

\"Brake<\/a><\/p>\n

Fluids in categories 3, 4 and 5.1 are glycol based,<\/strong> DOT-5 fluid is silicone formulated<\/strong>.<\/p>\n

This is an important difference – the fifth grade cannot be confused with any other.<\/strong><\/p>\n

In addition to the DOT classification, there is a completely separate category of brake fluids that contain mine<\/a>ral oil instead of glycol.<\/p>\n

\"Brake<\/a><\/p>\n

They are usually much more expensive than glycol fluids, but they have one important advantage – they do not absorb water.<\/strong> Accordingly, the boiling point declared at the start of service should not change significantly at the end of service life.<\/p>\n

This advantage, however, may turn out to be a disadvantage over time. By absorbing all the moisture, classic fluids protect the inside of the brake system from corrosion. When we choose mineral oil, it will be more difficult for us to avoid the problem of rusting brake lines due to water in them.<\/p>\n

Despite the significant price difference between mineral oil and cheaper DOT fluids, opinion is divided as to which grade to consider. It's hard to say anything specific.<\/p><\/p>\n","protected":false},"excerpt":{"rendered":"
