How to overhaul the brake light and how to replace the brake light?

Brake light switch contact ablation caused by poor contact, if the hands-on ability is strong, you can remove the brake switch and open the shell, with fine sandpaper to polish the contacts inside the switch can be solved, if you have difficulty in operating, you can only go to the 4S shop or repair shop to replace a brake light switch.

The brake light is generally installed at the rear of the vehicle, and the main color is a red light, so that the vehicle driving behind is easy to find the vehicle in front of the brake, and the purpose of preventing rear-end collision accidents occurs. The simple model is that the power supply passes through the insurance, and then to the brake switch, when the brake pedal is pressed for braking, the switch is connected, and the electricity is sent to two brake lights and a high-mounted brake light, and is connected with the car body through the negative line to form a loop.

Brake light function:

The brake light is the light that lights up when the vehicle brakes. It is generally red, which plays the role of warning the vehicles behind; In addition, the brake light can effectively prevent the occurrence of vehicle rear-end collisions and reduce traffic accidents.

The brake light is brighter and more obvious, and it is mainly used to remind the vehicle behind to slow down or stop. If the brake light is used incorrectly or malfunctioning, it is easy to cause a rear-end crash. Also, pay attention to replacing the brake bulb:

The tail lights of vehicles produced in China are generally"One brew for two purposes"There are two filaments in the bulb, the weaker one is the small light, and the stronger one is the brake light. Some manufacturers design it as a high and low foot plug-in type, which is very convenient to use. Be careful not to reverse the connection when replacing.

One, replace the bulb, two, replace the wiring, three, replace the control system.

It is best to go to a regular car shop for maintenance.

The process of replacing the rear brake light is as follows:

1. Open the trunk and unscrew the screws on the lamp with a screwdriver;

2. Replace the bad lights;

3. Put the new bulb on well, and then put the lamp on according to the original method;

4. In this way, it is safe to drive at night. Don't worry about fines.

Extended information: one is the brake light installed at both ends of the tail, which belongs to a kind of car tail light, and the other is the high-mounted brake light, which is installed in the upper part of the tail.

High-mounted brake light.

If you look closely, you can see that some of the new sedans have a square or rectangular red brake light in the middle higher in the back. The scientific name of this light is the high-mounted brake light, which is generally some distance higher than the brake lights on both sides of the rear of the car. The function of the high-mounted brake light is to warn the vehicle driving behind it, so as to avoid a rear-end accident.

Vehicles without high-mounted brake lights, especially cars and mini-cars with low chassis, are often not bright enough when braking due to the low position of the rear brake lights, and it is sometimes difficult for vehicles following them, especially drivers of trucks, buses and buses with higher chassis, to see clearly.

Therefore, the hidden danger of rear-end collision accidents is relatively large. A large number of research results have proved that high-mounted brake lights can effectively prevent and reduce the occurrence of car rear-end accidents. Therefore, high-mounted brake lights have been widely used in many developed countries.

Steps to replace brake pads:

1.First open the engine compartment and check whether the level of the brake fluid is in the normal position to avoid spilling during the brake pad replacement process.

2.Use a jack to align the support point at the bottom of the car, as for the fulcrum, you need to mark the position according to the car manufacturer, after all, the design of each car is different. Once aligned, it can be raised and removed when the tire is completely off the ground.

3.Then you can use a wrench combined with the sleeve to remove the bolts of the brake caliper, and then directly remove the brake pads.

4.Push the brake piston back in, install the new brake pads and you're done, of course, you have to install the original parts in the order in which they are disassembled.

5. Finally, after the installation is completed, you have to check the brake fluid level, if you press the brake pedal a few times, the fluid level is still within the normal range, it means that there is no problem.

There are two types of brake light replacement.

1. Replace the rear tail light bulb.

Remove the rear taillight, remove the bulb, install a new bulb, and install the rear taillight.

2. Replace the rear tail light assembly, there is no separate brake light, replace the assembly to remove the rear tail light assembly, and install the new rear tail light on it.

1. Open the trunk and unscrew the screws on the lamp with a screwdriver

2. Replace the bad lights;

3. Put the new bulb on well, and then put the lamp on according to the original method;

Fourth, it is safe to drive at night. Don't worry about fines.

Open the trunk lid, find the position of the brake light, find someone to step on the brake, find the brake light, take off the bulb and replace it with a new bulb, which is now an electronic bulb. Generally not bad.

Remove the lampshade, remove the broken bulb, and replace it with a new one.

To replace the brake light, you need to go to the repair shop or 4S shop to ask the technician to find a bulb that matches the vehicle and replace the previous brake light.

Workaround:

1. The brake switch is broken: In this case, the brake pedal and the brake induction switch are not in good contact or the induction switch is good, and it needs to be disassembled for inspection.

2. Brake pad wear and aging: brake pad wear and aging will also cause the brake light to be on all the time, this time to check the thickness of the brake pad, if the thickness of the brake pad is lower than the specified value, generally, then it is likely to break during driving and cause danger.

3. Lack of brake fluid: brake fluid plays a very important role in the braking system of the car, the force of stepping on the brake pedal from the pedal when driving, through the piston of the brake master cylinder, the energy is transmitted by the brake fluid to the brake cylinder located in the wheel, so that the brake pad is in contact with the wheel, so as to achieve the purpose of preventing the vehicle from moving forward.

The lack of brake fluid will also be accompanied by a significant lack of braking force, and even a loss of braking force will occur in severe cases. In this case, it is sufficient to replenish the brake fluid in time. The lack of brake fluid will cause the brake pedal to sink, causing the brake switch to be energized all the time, so the brake light will always be on.

Reason: The car instrument prompts please check the brake light means that there is a problem with the brake bulb of the car, it may be that the brake light is not lit, you need to check whether the brake light is burned or the brake light insurance is burned, if the brake light is burned, it can be eliminated by replacing the brake light with a new one.

The brake light is generally installed at the rear of the vehicle, and the main color is a red light to enhance the penetration of the light source, so that the vehicle driving behind is easy to find the brakes of the vehicle in front even in the case of low visibility, and play a role in preventing rear-end accidents.

How to replace the car brake light:1Use a Phillips screwdriver or sleeve to remove the bolts. 2.Pull the light assembly out of the rear pillar. 3.Turn the socket counterclockwise and remove. 4.Remove the old bulb and insert the new one.

Automobile brake lights, according to the position, are divided into three types: 1. Brake lights at the rear of the car; 2. The brake light on the dashboard of the car, that is, the brake indicator light; 3. High-mounted brake light. According to the materials used, it is divided into two types: gas car brake lights and LED car brake lights.

A tail light is a white light that is placed as close to the stern of the boat as possible to display an uninterrupted light. A horizontal arc of light of 135° is displayed from the rear of the boat to the inside of each side. The visibility distance is 3 and 2 nmile respectively depending on the captain's requirements.

It is used to display the dynamics of the ship and identify the dynamics of other ships, and to judge the situation of the ship crossing or overtaking.

The purpose of the car brake light and the high brake light at the rear is to facilitate the vehicle driving behind to easily find the brake of the vehicle in front and prevent the occurrence of rear-end accidents. The purpose of the instrument cluster brake indicator is to facilitate the driver to act as indicated when the rear brake light is on.

How to fix a faulty brake light:

1. Check whether the acre type of brake fluid is enough, or whether the brake pads are almost worn;

2. Red is a warning that you can't drive the vehicle, generally because the brake fluid or the handbrake is not loosened to the end;

3. Yellow also belongs to the warning light, but the degree is light, you can continue to drive, but you need to overhaul it immediately, such as the thickness of the brake pad is not enough, the ABS system is faulty, etc.;

4. Green belongs to the indicator light, the automatic transmission has a brake lock in order to prevent misalignment, and the gear is locked without stepping on the brake, and the green light of the instrument is on, and it will be extinguished when stepped on, of course, it will not be lit during driving.
