How to solve the problem of non return of hydraulic brakes for electric vehicles?

Clause. First, to check whether the brake handlebar is seriously worn and can not return normally, if the wear is serious and can not be used normally, we have to replace the small handle and small handlebar.

Clause. Second, to check the brake cable, to see if the brake cable is water and has rusted, if the brake cable water and rust, you need to replace the brake cable, especially pay attention to both ends of the cable, because these two ends are the most likely to enter the water and rust.

Clause. 3. Check the brake drum cover to see if the rocker arm on the brake drum cover has rusted and locked, if the rocker arm on the brake drum cover is rusty and locked, it will also lead to poor brake return performance. This situation is a common problem on the brakes of electric vehicles, and the way to deal with it is to remove the brake drum cover, and then remove the brake rocker arm for cleaning, and then put on the oil and butter before installing it back.

After the above three situations are dealt with, there is basically no problem with the brakes, and the brakes of the electric vehicle can be used normally.

1.Rust, because the braking system of electric vehicles is mostly drum brakes, drum brakes, and the power transmission parts of drum brakes are generally cables, and the cables are easy to rust during use because of the wear of the inner bushing, and the brake rocker shaft of electric vehicles is also easy to rust.

2.Wear, excessive wear of the brake pads not only affects the braking effect, but also affects the return state of the brakes.

3.Spring, return spring fracture of this kind of fault is generally a little more likely to occur in three-wheeled electric vehicles.

4.In the event of such a failure, the first thing to do is to determine whether the brakes are working properly, as the brake pads are not overworn. Then you should focus on checking the brake cable and the brake rocker arm shaft as well as the brake return spring.

If you find that the hydraulic brake does not return to its position, do not disassemble it first, fill 4 6 drops of engine oil from the outside (dust cover side), and operate the handle several times after 5 minutes, and the basic problem can be removed.

The oil brake does not return to the wheel brake lock or normal brake, most of the reasons are the brake cylinder inside the brake drum rust does not return, and the main cylinder rust does not return to cause the brake not to return.

Electric vehicles and motorcycles hydraulic brakes do not return to hold the wheels, disassemble and repair and explain in detail.

The failure of the brake to return will also lead to the failure of the electric vehicle to drive normally due to the failure of the brake power. Generally speaking, the brakes do not return due to the following problems.

1. Brake handle, check whether the brake handle is seriously worn and can not be returned normally, if the wear is serious, we only need to replace a brake handle to solve the problem.

2. Brake cable, check whether the brake cable is rusted due to water ingress, if the brake cable is rusty, we need to replace the brake cable, especially pay attention to the tail end of the brake cable and the bottom position of the electric vehicle, the tail end of the general cable is caused by the rain that is often seen, and it is extremely intentional to cause rust.

3. Check the brake drum cover to see if the brake rocker arm can move normally, and break it with your hand to try to bounce back by itself. If the brake rocker arm cracks and can't bounce back on its own, or it doesn't move at all. At this time, we have to open it to clean up, first remove the wheels, remove the brake drum cover, and remove the brake pads.

Use 8 to 10 wrenches.

Remove the set screws from the rocker arm. Take out the rocker arm, clean it up, put on the butter and install it on the line, generally the brake does not return based on these 3 situations, according to the above steps to deal with, there is no problem, the electric car brake can be used normally.

The front brake of the electric car does not rebound is caused by 3 reasons:

1. If the brake return delay spring is broken or loses its elasticity, this phenomenon can replace the brake pedal return spring.

2. There is a problem with the axle of the front wheel of the electric vehicle, which affects the braking system.

3. Check whether the brake rope is broken or rusty, often walk on the road with water, the brake line will rust, if such problems occur, the brake rope needs to be replaced and can be used normally.

1. The car's return spring is damaged, resulting in the brake not being able to rebound to its original position.

There is a response spring in the braking system, which returns the brakes to their original position after they have finished working. However, when the spring is damaged, it will affect the operation of the braking system. The solution to this problem is also very simple, the owner can replace the return spring with a new one.

2. There is a problem with the axle of the front wheel of the electric vehicle, which affects the braking system.

When the front axle of the car fails, it will also make the brakes of the car unable to rebound. The owner can first check what is wrong with the front wheel, and if it can't be solved, it needs to be sent to Hu Xiao for repair as soon as possible.

3. The brake line of the car failed, so that the brake could not rebound in time.

Sometimes there will be some faults in the brake line, resulting in the brake not being able to rebound to the original place in a short time. At this time, the owner should not be in a hurry, repeat the brakes a few more times and try it, so that it may return to normal.

Hello, I am a cooperative teacher Xiaoyang, good at the field of auto repair, has been engaged in the auto repair industry for 6 years, good at analyzing problems, finding out problems and solving problems, and serving customers from modification to maintenance Very detailed I have received your question, it takes a little time (3-4 minutes) to type, please wait a while, please do not end the consultation, you can also provide more information, so that I Zheng Zhichang can better tease and balance for you to answer, I am happy to serve you

Hello dear, I'm glad to be able to serve you according to your description, the electric car shows that the brakes can't go what to do as follows.

Hello, what should I do if the electric car shows that the brakes can't go: first check whether your left and right brake systems are damaged, such as the brake handle can not automatically bounce up, the line is short and fast, etc., which will make the controller connect to the virtual to the command to display the brake and control the motor to start. Most of them are brake handles or wiring problems, but they can't be ruled out as controller problems.

Hello dear, you basically have a broken brake system, and you can only push it to repair, and there is no way to temporarily lift it.

Hello, electric vehicle faults are mainly divided into three types: 1. The whole car is out of power - the main fault is that the battery is welded, the insurance is burned out, the power cord and the battery socket fall off, the contact is poor, and the converter is damaged. There will be no big questions.

2. If there is electricity, do not go - under normal circumstances, you first look at whether the brake handle is back in place, if the brake handle is disconnected, you can drive the brake handle with your hand against the stupid luck, in addition to the above situation, turn it. The controller is damaged. The motor is damaged.

Hall damage will be a bit of a non-go. In this case, there is a possibility that the power supply will be broken, so be sure to find a professional to check and repair it for you. 3. There are some special circumstances:

The car is boring, sometimes it walks, sometimes it doesn't, the power consumption increases, and the mileage of the car is short. One may be the battery is damaged. The second tire pressure is insufficient.

Third, the brakes are too tight.

Hello, dear, thank you.

The main reason why the brakes do not rebound is because of the letter

1. The brake fluid of the sliding rubber part of the brake system.

The remaining amount is insufficient or there is a quality problem with the brake fluid, once the brake fluid is out or the problem is present, the entire brake system will fail;

2. The brake oil pump fails, resulting in the brake being unable to rebound;

3. There is a problem with the shaft of the front wheel.

If the brakes cannot rebound during the use of the vehicle, the driver first needs to release the accelerator pedal to let the vehicle gradually slow down until it stops; Subsequently, the brake line inside the braking system is adjusted, and if the brake line is too loose, the driver needs to tighten it slightly; If the brake line is too tight, it is recommended that the driver call for help in time to deal with it.

There are 3 reasons why the front brake of an electric vehicle does not rebound:

1. The brake return spring of the yard state is broken or loses its elasticity, and this phenomenon replaces the hydraulic pedal.

The return spring will do the trick.

2. There is a problem with the axle of the front wheel of the electric vehicle, which affects the braking system.

3. Check whether the brake rope is broken or rusty, often walk on the road with water, the brake line will be rusty, if there is a problem such as Zen, the brake rope needs to be replaced to be used normally.

1. This is because the switch of the brake line is broken, it has been disconnected, and the circuit cannot be connected. The signal source of brake power failure is formed after collecting the action of the brake switch, if the brake switch is stuck or malfunctioning, it will cause the vehicle to have power and cannot go.

2. The problem is that the brake handle cannot be completely returned to the position after being released, it is not an electronic brake at all, because it cannot be completely returned, so it will be in a state of slight braking, and there is a component in the brake handle that will cut off the power supply of the motor when braking, so the power is cut off.

3. All the switches on the car are to control the positive pole, including the brake switch, when the brake is pulled up, a positive signal passes through the tail light and the controller, forming the purpose of brake power off and brake light at the same time. The principle of the bottom level is the same as that of the high level, but it is only co-positive, and the brake switch is the negative pole of control. Whether a car is high or low depends mainly on whether the controller is high or low.

1. The brake power-off switch is broken. Mechanical normally open and power-off switch, continuous action, after a long time the contact point is corroded or the elastic force of the shrapnel decreases and the contact point cannot be contacted, so that the brake can not be cut off, and the switch is damaged! It can be solved by grinding the contacts and adjusting the shrapnel, but if it doesn't work, please replace it!

For electronic switching circuits, replace the entire set of brake levers if the connector or wire is not broken. Clause.

Second, the brake does not return, and the car does not go. The brakes of electric vehicles do not return to the position, and the brakes are disconnected into a disconnected type, which causes the car not to go, and you can go by touching the brake handle with your hand, which is mostly caused by the brakes not returning! The reasons for not returning the brakes are: a....

Summary. Dear, I am glad to answer the battery car rear brake, how to deal with the battery car rear brake if the brake does not move, the brake treatment method is 1, replace the rear brake assembly, or tighten the adjustment screws. Under the rear brake there is a pull wire with a spring, and a nut at the end of the spring.

Twisting in the clockwise direction is to tighten the brakes, but can not adjust the si, the rear wheel of the car can be rotated at will, and it can not be adjusted only to replace. 2. Replace the brake pads, and preferably replace them together with the brake cable.

2. Replace the brake pads, and preferably replace them together with the brake cable.

The main reasons why the battery car brake cannot brake are brakes, brake pads, tires, brake fluid and so on.

1. If the brake is broken, or the brake is loose, you must first go to the repair department to check it, if it is loose, it will be tight in the back, and the brake will be changed quickly. 2. The brake pad is seriously worn, and the brake block can be replaced. 3. The tire will provide friction and resistance during the rolling process, but once the tire pattern is seriously worn, the friction it can provide will also be greatly reduced, and then it will be obvious that the car cannot be braked, and this feeling will be more obvious in rainy days.

4. The brake fluid has expired. When the brake fluid becomes no longer pure, its viscosity will rise, and the brake fluid with higher viscosity will affect the braking force transmission of the vehicle.
