What should I do if I can t brake when I change the brake pads of an electric car?

First: In life, when the electric car rides for a long time, there will be a lot of problems, in fact, these problems can also be found in the process of riding, so in the process of riding, we should pay more attention to these problems, once we find that there is a problem, we will deal with it immediately, so as to prevent unnecessary problems with electric vehicles.

Second: there is a spring under the rear brake of the electric car, this spring is related to the rear brake, if you feel that the brake is not working, you want to adjust the spring, but you can't adjust it too tightly, and the wheels will not change if you adjust it too tightly, so it is generally necessary to adjust it appropriately. If the spring can't be adjusted, you have to replace the rear brake with a new one.

Third: Sometimes we can't find the brake quickly, in fact, it is easy to find, you can find it by looking down the line of the brake, and there is a screw, which can also adjust the brake. In life, electric vehicles have to solve the brake failure, can not be ignored, to check the problem there is the first time, if you can't find out the problem, you have to go to a professional repair shop for inspection and repair.

If the front disc brake is not working, then you need to refuel the disc brake, and then adjust the brake sensitivity The first method, the car is upright, disassemble the oil reservoir cover on the handlebar, and then there is an air port protected by a holster on the disc brake caliper on the wheel, unscrew him, and then you can release the oil after unscrewing and then refuel from the oil reservoir, catch the oil with a basin under the air port, and wait until the oil is out of the air port without bubbles.

Brake pads, also known as brake pads, are the most important components in the automotive braking system, and the automotive braking system has an unshakable position in the braking system of the car, that = so drivers pay great attention to the maintenance and replacement of automobile brake pads, but the recent friends asked me why the brake pads I just replaced can't brake, so today I will introduce it to you!

Why can't the brake pads just been replaced - introduction.

The replacement of brake pads depends on how long your gasket has been used in your car. Generally speaking, the replacement cycle of the front brake pads is 30,000 km, and the replacement cycle of the rear brake pads is 60,000 km, and there may be slight differences between different models. However, if you hear the grinding sound coming from your wheels, you should replace the brake pads no matter how mile you have.

Why can't the brake pads just been replaced - introduction.

Brake pads are made up of steel plates, bonded insulation and friction blocks, and the thickness varies depending on the degree of wear of the new brake pads and the brake pads used. The used brake pads are run in with the brake disc, the contact surface is large, and there are a lot of unevenness, and the braking force is strong; The surface of the new brake pad is relatively flat, and the contact surface with the brake disc is small, the braking force will decrease, and the new brake pad will not be able to brake.

Why can't the brake pads just been replaced - introduction.

Therefore, when replacing new brake pads, it needs to go through a period of running-in. Generally speaking, it takes about 200 kilometers to achieve the best braking effect. Here's how to run in the new brake pads:

For the introduction of why the brake pads that have just been replaced, we have introduced the cycle of replacing the brake pads, the composition of the brake pads and the precautions for replacing the brake pads. I hope the introduction can help everyone

If your electric car brake pads can't brake when you change them, they are not adjusted well, you can tighten the brake spring for it, and then adjust it to make it easier.

If the electric car changes the brake pads and can't brake the car, it can only mean that the brake pads are of the wrong quality.

First of all, rule out whether it is the fault of the brake power-off switch (the motor should be powered off during normal braking, and the car cannot be braked because the power is not interrupted when the fault is broken), and then find a car repairer to polish the brake pads with sandpaper to improve the braking performance.

If you can't brake the brake pads of your electric car, then you can adjust the tightness, because the tightness can definitely be adjusted.

Hello It may be that the brake pads are not in good contact. 1.As the name suggests, it is a mechanical braking device that can slow down the speed of the car, also known as a reducer. To put it simply: the car brake pedal is under the steering wheel, press the brake pedal,

If the brake pads of the electric car still can't brake the car after being replaced, it must be the brake line or the brake oil pump has a problem.

The brake pads of electric vehicles can't be braked when they are replaced, and the brakes should be relatively loose, so the brakes should be tightened.

What should I do if I can't brake when I change the brake pads of electric vehicles? It could be that you have a problem with your electric car, or that one of yours has a problem with the brakes, and you can take a second look at its brake conditioner brake pedal.

It is recommended to go to a repair shopIf it is an oil brake, it should be that the oil pressure is not enough or the brake pump is not sensitive.

There is also a possibility that your brake pads and brake discs are getting oil and can't brake.

The car can't brake is not only a brake pad problem, the brake disc is seriously worn, the combination between the brake pad and the disc is not good, the brake stroke is not enough, and the brake pad is not pressed on the brake disc and so on. This needs to be disassembled by a professional master to take a look.

I can only change the car, because the brake function of the electric car is broken, and it is very dangerous to drive on the road.

The electric brake pads are changed, and the car can't be braked on the road, which means that your brakes are still problematic and unsafe.

That is. There is a problem with the brake system.

If your electric car brake pads can't be changed, it is not adjusted well, you can tighten the brake spring for it, and then adjust it to make it easier.

The braking effect of the brake pads that have just been changed will not be the best because of the running-in process! You've just changed the brake pads, right? If it is just changed the brake pad soon after the ring, it is very normal, as long as you think about it for a while, it will naturally not sound, because the new brake pad, his surface is very rough, as long as the run-in for a period of time, its surface is smooth, and it will not sound again.

Summary. Hello, the bad brakes of the electric car disc brakes may be due to insufficient brake fluid or worn brake pads. Many of the larger electric vehicles use disc brakes. The principle is to use hydraulic oil to push the brake pads to rub against the stainless steel pads to brake.

To repair the disc brake, first check whether the brake fluid of the disc brake should be changed and whether the brake fluid leakage is good. If it doesn't leak, Panasonic oil drain screws will do. The second is to see if there are bubbles in the outflow oil, and if there are any, drain the oil until there are no bubbles; Finally, check whether there is pressure on the brake lever, and if there is no pressure, just open the air exhaust screw on the lower pump.

What's going on with the disc brake in front of the electric car that can't brake at all?

Hello, happy to answer your questions.

Generally, the brake disc does not spring back because the disc brake piston does not return to position.

1. The piston is rusty.

The reason is that the piston is rusty due to natural conditions such as water ingress or corrosion, which makes it impossible to produce a normal springback.

Treatment: Remove the lower pump, hold the brake 2-5 times, wait for the piston to come out 5-10mm, and remove rust. You can spray rust remover or fine sandpaper and turn it on the piston several times. After processing, the piston is pressed back and loaded.

2. Aging and expansion of rectangular rubber sealing ring If the piston is smooth and difficult to press back, consider the aging, expansion and deformation of the sealing ring.

Treatment: The rectangular rubber seal must be replaced.

1.Wear and tear of brake pads and discs results in a thinner thickness. For example, disc brakes, calipers (also known as brake pads) clamp the brake disc brake for a long time, and after a long time, friction will make the surface of the caliper and the brake disc become thinner and thinner, which will make the travel side of the brake pedal longer;

2.Wear and tear of the tires. The life of tires is generally about 60,000 kilometers, and the tread of tires that are close to life will be ground very thin, reaching the wear mark in the tire groove. The adhesion between the tires and the ground will also deteriorate during the long wheel rotation period, resulting in a long braking distance from the side of the brake;

3.Problems with brake fluids. At present, the braking system of most cars is hydraulic braking, which requires the pressurization of brake oil to transmit this braking force to the brake pads.

When the brake fluid is compressed, the volume is not easy to reduce. However, friction generates heat, and when the brake pad vigorously applies the brake disc, it will produce high temperature, and the high temperature will be transmitted to the brake fluid through the brake pad and the Youpai brake cylinder.
