Stop signals are called red signals that indicate the braking of the vehicle. Automatically turn on with the smallest of click on the brake pedal, and when it is pressed, it is also automatically turned off. Stop signals are a mandatory element for any land transport - they must be symmetrically arranged, to work with minimal braking or stop, as well as, to be brighter dimensions.

Stop signals are an extremely important part of the vehicle, since they allow the surrounding drivers exactly to see the outlines of the vehicle and predict the motorist's maneuvers. If the stop signals on the car do not work - it threatens not only a fine on a round summit, if you are noting the traffic police officers, but also more serious problems, for example, a collision or, even worse, severe accident on the road. Therefore, if the stop signals stopped burning, it is necessary to eliminate this malfunction as quickly as possible. In addition, as a rule, the causes of the failure of the stop signals are quite banal and can be eliminated by the problem independently, without contacting the service center.

Stop signals do not work, how to find the cause

Most of the vehicles are equipped with three hundred signals, two of which are located in the rear lights, and the third - upstairs under the roof or on the hood. Additional stop signals began to be used since 1990 on serial vehicles as an additional security device.

Stop signal system is a simple electrical system that is fed from the vehicle battery. It is protected from a short-circuit fuse, which is located in the cabin fuse box. It gives the switch located on the brake pedal. In one whole, all components of the system connect the electrical wires. If the system is working normally, then when you press the brake pedal, the stop light bulbs should be lit. If the system is faulty, it is necessary to determine the causes of this breakdown, and there are several of them:

1. Wiring wear.
2. Faulty brake light switch (confusion, frog).
3. Through the fuse.
4. Oxidation of stop signal fuse contacts.
5. Contacts were oxidized in the lamp nest.
6. Burned lamp brake lights.

The most common causes are blown lamps, fuses and oxidation. Therefore, first of all, the check must be started with them, and if we speak more precisely, then from the vehicle salon, because it is here that the common fuse block is located. It is under the steering column opposite the driver's seat. To date, there is no specific order of fuse alternation for all car models, according to this, vehicle manufacturers carry out the location of the fuses at their discretion. To identify the fuse, which is responsible for brake lights, it is necessary to pay attention to the technical instructions of your vehicle.

Fuse block, where is located, how to check the fuses

On many car models for brake lights and a beep, one fuse responds, so they are such machines to check its performance, it is necessary to simply press the CLAKSON button. If there is sound, then the fuse is in order. If no sound, you need to replace the fuse. However, even with the presence of a sound signal, it is necessary to fully inspect the entire node for the presence of corrosion of contacts. To carry out prevention, it is advisable to clean and lubricate the contacts with an electrically conductive special lubricant, which will protect them from the formation of in-nagar and oxidation.

Brake lamps how to check them for performance

If the fuses are all right, you need to go further. You should open the luggage department and disassemble the rear headlights to check the integrity of the brake lamps.

It is advisable to check them by inserting spare lamps, as very often with visual inspection, the lamp may look workable. If there are no spare lamps, remove suitable lamps from other places, for example, from turning repents, overall lights, and so on. After replacement, click on the brake pedal and check the presence of light. It is necessary to replace other operations in both headlights, because in some vehicles at the exit of one stop signal, the second is also stopped working.

If the light appeared, then the cause of the breakage was really brake lamps, if it was not possible to eliminate the fault, go to the next step - checking the contacts.

Checking contacts

If you have not received a positive result from replacing lamps, you need to check the contacts in places where the cartridge is connected to the wiring and in the chamber itself.

It is necessary to thoroughly clean all the contacts and apply electrically conductive lubricant. After that, you need to check the brake lamps again. The fact is that the causes of the failure of stop signals may be mass, and in some cases, there may be two or three at once, because no one is immune from such a coincidence.

Brake confectioner how to check the work of the end

The people of the people are referred to as a frog or brake lights switch, and this device is mounted for the brake pedal. The main thing when dismantling does not confuse it with a frog of clutch or with a cruise control end, if there is such a configuration of your vehicle. When you press the brake pedal, the stop contacts are closed in the frog, with the result that the circuit of the chain occurs only at the time of braking and the stop signal is not lit constantly.

Details of the closure in the confusion are able to oxidize, corrosion and naigre are rare on them. Dismantling the frog is not difficult, you just need to turn the frog counterclockwise about ninety degrees and pull on yourself. Then we disconnect the wiring from the terminal and check its performance. If the lanterns of the stop signal were lit with the independent closure of the disconnected wiring, then the malfunction was the switch.

In this case, you can buy a new confusion or disassemble the old one and try to repair it on your own. To do this, it is necessary after disassembling the element, thoroughly clean all the contacts and rinse them in alcohol. After that, lubricate the electrically conductive lubricant and assemble back. Next, we connect the wiring and mount the terminal to the socket - insert and turn clockwise on ninety degrees. Now it remains to check the result by pressing the brake pedal.

Wiring, How to Check, Step-by-step Instructions for Slorage Sliver Wiring

Search for trifles in the wiring of the vehicle, perhaps the most confusing procedure. To carry it out, it is necessary to arm a multimeter and proceed to the study of electrical wiring. It is advisable to start from the terminal and check the availability of voltage when exiting it. This will help immediately determine in which the sector has a breakdown occurred. If the output is the presence of voltage, you should check the entire wire that goes from the terminal to the pharmaces. However, there is a simpler way - just replace this wire zone to the new one. It is worth noting that the wear of the electrical wiring happens extremely rarely.

Stop signals are constantly burning, why and how to eliminate the cause

In addition to all the above troubled signals described, there is another, no less dangerous, but it is possible to solve it much faster and easier. If the stop signals are burning constantly, this suggests that when braking, the terminal closed the chain, and the opening did not happen. To correct this problem, you need to disassemble this element, clean the contacts, correct the ears of the contacts to ensure the lung and smooth slip and check the spring, because it might burst. After that, the contacts must be rinsed with alcohol, lubricate and collect everything back. If you find that the spring burst, it is advisable to buy a new confusion.

Tips of professionals

It is necessary to regularly and constantly check the performance of braking lights of your vehicle and in no case pull with repair if the stop signal has failed.
