What is the effect of water on hot disc brakes?-Expert reviews

I have seen many people give water when the bike’s disc brakes get hot while riding a mountain bike. Normally, disc or drum brakes lose their effectiveness when they get hot. And many people put water on the disk to bring the dix to normal from this wheat.

I will try to find out from today’s discussion what the effect of water on the hot disk is. ?

Effects of temperature change:

Pouring or using water on a hot engine is really a harmful practice. But we have been doing this without knowing it for a long time. It is necessary to know a little about the exact effect of the change in temperature that occurs when cold water is poured into a hot engine.

Heat has a direct effect on matter. When the temperature of a substance is increased, the molecules in the substance vibrate in place. If the temperature is increased, the vibration of the anu increases in proportion to the heat.

And after a certain temperature, the vibration of the anu increases and moves away from its place.
And in view of this condition, matter changes from solid state to liquid, and from liquid state to gaseous substance And there is a radical change in their characteristics.

And in this process, the shape of the material also changes dramatically.

On the other hand, when the temperature of the substance is lowered, the reverse process occurs. In that case, the molecules of the substance become densely packed.

As a result, the gaps between them are completely reduced. And usually, at the end of the heat loss, the particles lose their attractiveness. As a result, the material loses its own strength and flexibility and is forced to assume a brittle nature.

Rapid heat change in solids:

After the general science discussion, the question comes up: if the temperature of a substance is changed very quickly, what actually happens?

Essentially, liquids and gases respond proportionally to these rapid temperature changes. In this case, their molecules rapidly change position, the density of matter decreases and increases in range, and finally they lose their specific shape and evaporate.

However, if the standard temperature of gaseous and liquid substances is ensured, they return to their previous state. However, in general, the instantaneous temperature change on solids, especially metals, is slow and quite negative. And the effect is worse when a partially instantaneous temperature change is applied to the metal.

The molecules cannot react fast enough in proportion to the instantaneous temperature rise of the solid. And even with a sudden drop in temperature, the scattered waves cannot return to their original location very quickly.

Basically, given such conditions, solids lose some of their standard temperature properties. As a result, the material loses its normal strength and flexibility and becomes brittle.

So the dangerous level of sudden temperature change here can easily be imagined. And in the language of science, it is called thermal shock, which has a special effect on metal materials.

So far, our discussion has focused on the effect of temperature change and what happens to solids when heat changes rapidly. But our main topic was to discuss the effect of cold water on hot disc brakes on bikes.

But the first two things are involved in our discussion of this matter, so we have discussed it. So let’s know in this discussion what the effect of cold water is on the hot disc brake of the bike.

Effect of cold water on hot disc brakes on bikes:

What can actually happen if you pour cold water on a bike’s hot disc brakes? If you pour water on a hot disc brake, you will see that the water evaporates quickly.

In this case, the water evaporates by absorbing heat from the surface of the crankcase of the disc. But the dangerous thing is that the inside of the crankcase remains at a high temperature. As a result, there is a huge difference in temperature between different parts of the same crankcase.

And the more dangerous thing is that the poured water absorbs heat only from the poured part instead of absorbing the temperature from the entire disk.

So in this case too, the temperature difference is pronounced and the disc is subjected to severe thermal shock. In this situation, many may say that they have done this many times

but to date, nothing has happened to their bike brakes! But why is there such a question to be aware of?

The answer is that they are very lucky that the bike’s metal components are strong and durable enough to withstand such shocks. But it is also true that the ill effects of these indiscretions and bad habits are far-reaching. But let’s see how cold water can affect hot disc brakes.

What can happen if cold water falls on a hot disc brake?

• If you pour water on a hot disc brake, the disc may crack. More importantly, water will touch the disc rotor and cause it to crack or warp. The brake calipers are inside the assembly, so they aren’t really affected in real life. Cooling a hot disk with water is a really bad method.

Pouring cold water on a hot disc brake gradually causes the disc to lose its normal strength and flexibility and become brittle.

• The effect of water on heated disc brakes can cause rust, corrosion and dirt on the grooves, bolts and other parts of the disc.
• It reduces the life of the disc brake and makes the ceramic jacket of the disc brake brittle.

We should take care of all aspects of the bike and ride it according to proper rules. Many people were not aware of the effect of cold water on the heated disc brakes of bikes. But it all came up in this discussion.

So, if you do not follow your own rules, follow the correct rules, and the bike will give you the best service for a long time.
