How to dry the brakes — Lifehak from the car mechanic


9 months a year In Russia, the season of wet roads: puddles, slush and wet every centimeter of brakes, suspension, transmission.

What trouble can lead to and how to dry the brake system with strong humidity — will tell the car mechanic Pavel Chudinov with 20 years of experience.

Peter Mikhailovich, what threatens the increased humidity?

Water flows and splashes, hitting the braking parts of the brake system, lead to their wet. As a result, the coefficient of friction is reduced, and braking becomes not effective enough. This is a danger. Wetting the pads leads to an increase in the braking path just a few meters, but in the accident situations such a difference can be critical. Therefore, experienced drivers after entering deep puddles always dried the brakes. This useful habit of saved many lives and property.

Different brake systems are dried equally?

There are nuances. For example, the working bodies of the drum type brake are two pads, divergers in opposite sides. When braking, they clamp the wheel. Drum brakes are reliable, but not protected from wetting. It gets water not only from the puddle, but also after washing. In addition, condensate can accumulate inside the drum. Any moisture on the pads becomes the cause of bad braking: they begin to slip on the surface of the disks.

How to quickly dry drum brakes?

This can be done on the go, intermittently by pressing the pedal several times and gaining speed. During the braking, the shoe and the drum will be drunk from each other and heated, this is enough so that the moisture evaporated. After a few long-lasting braking in a row, the water delayed in the brake system will disappear. The order of action is:

Important moment: if there was no time to dry the brakes during the day, and the frost happened at night, in the morning the car does not touch. In this case, heating the drums of hot water filled into polyethylene packages.

And what about disk brakes?

The working part of the disc brakes are two pads. They converge and compress the disk on both sides, slowing the rotation. There are no closed parts in disk brakes that hard to dry. They are well ventilated and quickly dry under the pressure of air entering during the ride. However, disc brakes, like drum, watered in the rain. Then you need to dry. This can be done on the go, accelerating and slowing down, as well as in the case of drums. Please note: in many modern car models there are rain sensors that include drying brakes in rainy weather.

Are there any general rules for safe braking in the rain?

They are elementary. So that the brake pads do not pour, do not move the puddles at high speed. Check how the brake system works after car wash or downtime. Having drove on a deep puddle, check the operation of the brakes, once pressing the pedal. If there are doubts about the efficiency of the pads, dried with additional braking. It would seem trifle — wet brakes. But how much inconvenience she can deliver, you can not imagine! We always have an influx of visitors in the car service after heavy rains.

Thanks for the recommendations.
