The brake discs and brake pads have been replaced, and the brakes are still shaking

If the steering wheel is shaken, it may be that the horns are slightly deformed, the bearing is loose, and the axle head is deformed may affect the brake left and right. If the brake pedal is shaking, the brake pads and brake discs are problematic, and you say that the brake pads and brake discs are replaced or don't work, that is the problem of the chassis, the ball head is loose, and the bushing gap is large, which may cause the brakes to shake.

The brake disc, simply put, is a round disc that rotates when the car is moving. If the brake caliper clamps the brake disc and generates braking force, it clamps the brake disc to slow down or stop when the brake is pressed. Brake discs brake well and are easier to maintain than drum brakes.

The brakes currently have disc brakes, drum brakes and air brakes, and many older cars have front and rear drums. Many of today's cars have disc brakes front and rear. Because the disc brake has better heat dissipation than the drum brake, it is not easy to produce thermal decay in the high-speed braking state, so its high-speed braking effect is good.

However, at low speed cold brakes, the braking effect is not as good as drum brakes. **More expensive than drum brakes. Therefore, many middle and high-end cars now use full disc brakes, while ordinary cars use front disc and rear drums, while relatively low-speed, and need large braking power for trucks and buses, still use drum brakes.

The drum brake is sealed, shaped like a drum, and there are many brake pots in China. It turns when driving. There are two curved or semicircular brake shoes fixed on the inside of the drum brake.

When stepping on the brakes, the two brake shoes are stretched outward under the action of the brake wheel cylinder, and the brake shoes are propped up and rubbed against the inner wall of the brake drum to play the role of deceleration or stopping.

Disc brake discs (discs) are divided into solid discs (monolithic discs) and air duct discs (double-disc discs). The solid disc type is easier for us to understand, and to put it bluntly, it is solid. Vented disc, as the name suggests, has the effect of ventilation.

From the outside, it has many holes in the circumference that lead to the center of the circle, called air ducts. The purpose of heat dissipation is achieved through the air convection at the air duct during the exercise, which is much better than the solid heat dissipation effect. Most of the cars are front-wheel-drive, and the frequency meter of the front disc is worn out, so the front air duct disc and the rear solid disc (monolithic disc) are used.

Of course, there are also air duct discs at the front and rear, but the manufacturing cost is not outrageous.

The steps of disassembling and assembling the brake disc are: 1. Disassemble the tire and the brake cylinder; 2. Disassemble the rear wheel assembly, and use special tools when disassembling the rear wheel bearing cover, so as to avoid destroying the seal of the bearing cover when prying it open with a slotted screw; 3. Disassemble the baffle of the rear brake disc, and clean up the dust in the bearing sleeve after dismantling; 4. Install a new brake disc baffle, tighten the rear wheel bearing and install the bearing cover; 5. Take out the sub-pump bracket; 6. After installing the brake pads, install the brake cylinder, and tighten the screws of the cylinder and the bracket; 7. Install the hub.

After a long period of driving in the car, and there has been a certain number of braking processesAt this time, the brake disc has a very high temperature, and when the emergency brake is activated to ABS. We know that ABS is an anti-brake lock system, that is, an electronically controlled point brake, through the brake cylinder caliper to the brake disc continuous tightening and relaxation of the action, so that the brake disc is intermittently stretched strongly, when the brake deceleration is applied in the vehicle, heat is generated.

Brake: As the name suggests, it is a mechanical braking device that can slow down the speed of the vehicle, also known as a reducer. In a nutshell:

The brake pedal of the car is under the steering wheel, and when the brake pedal is pressed, the brake lever is pressurized and transmitted to the brake pad on the brake drum to jam the brake wheel, so that the car slows down or stops running.

1. Solid brake disc.

A physical brake disc is a metal disc used for braking. This type of brake disc has a simple structure and is cheap. However, the heat dissipation effect is poor, so the thermal braking effect is relatively poor.

2. Ordinary ventilation type.

The normal ventilated type is an improvement on the basis of the physical brake disc. The heat dissipation performance has been enhanced, and the braking effect is more stable, which is currently used in most cars.

3. Perforated brake discs.

The perforated brake disc has better cooling, shortens the braking distance, and has a more stable braking effect, which is generally suitable for high-end cars.

4. Scribing brake discs.

The dust and debris attached to the brake disc can be discharged, and the rainwater can also be discharged when the road surface is wet in rainy days, so that the car will not be affected by excessive rain on the brake disc.

5. Ceramic composite brake disc.

It is made of a mixture of carbon fiber, graphite and silicon, whether it is hot or cold braking, it has better braking performance and longer service life, and is generally used on high-end cars or high-end sports cars.

That shakes when you brake. In addition to the deformation of the brake disc, there could also be the cause of the tires. For example, the tires are worn on the side, and there will be some shaking when braking.

It could also be hanging inside. Swing arm. The rubber sleeve is loose.

A component bolt. Loosening, etc., also check the suspension. Fastening of the components and bolts inside.

First of all, I am doing brake discs, not car repairs, so what I said is not necessarily right, generally speaking, the brake disc or trembling is most likely to be the brake disc and the brake pad do not match, one of them is hard, such a situation is the most cause of brake shaking, other reasons are the repairman installed the brake disc is not installed in place, if not in place or the brake disc is not fixed well, this phenomenon may occur, you can try to replace the brake pad together to see the effect. If it shakes without braking, it is generally not a problem with the brake disc, it may be that the tires need to be positioned, this is purely my own experience, my car has been in this situation before.

Or the brake disc is still shaking after braking, that's not the case, it should be uh, a few chicken feet Captain Luster may be broken.

If you feel shaky when braking, it means that your brake disc and shoe are not working on the same level when they are working together, and the brake disc is scooping. You've just replaced your brake discs, so you need to pay attention to whether your brake discs are completely separated from the brake shoes when they are working properly. If there is friction, the brake disc will be very hot after friction, and it will be deformed when it is cold.

How to check whether it is completely separated and after driving for a while, use a thermometer gun to detect the temperature of the brake disc.

Help me brake the disc or shake, then you can look at other aspects of the problem!

Just brake shaking? Do you tremble when you run?

If your brakes are still shaking after installing new brake discs and pads, it could be one of the following reasons:

Brake discs are not installed correctly: If the brake discs are not installed correctly, such as bolts that are not properly tightened or the brake discs are not aligned with the hub, it can cause brake jitter. Therefore, you should make sure that the brake discs have been installed correctly.

Uneven brake disc surface: An uneven brake disc surface can be caused by excessive wear, overheating, or bending. In this case, the brake disc needs to be re-smoothed or replaced.

Uneven wear of brake pads: If the brake pads are worn unevenly, it can cause brake jitter. This can be caused by poor quality brake pads or brake pads that are not installed properly. Therefore, you should make sure that the brake pads are properly installed and that you choose high-quality brake pads.

Brake system failure: Brake shake can also be caused by a malfunction of other parts of the brake system, such as a cracked brake hose or a stuck brake caliper. In this case, other parts of the brake system need to be checked to make sure they are working properly.

If you are not sure what the problem is or cannot solve the problem, it is advisable to consult a professional car mechanic for inspection and repair. The braking system is an important part of the car's driving safety, and any faults should be resolved as soon as possible.

1. The plane of the brake disc, the closing head and the shaft head are uneven; 2. The manufacturing error of the brake disc leads to brake jitter; 3. The torque of the split disc and the closing screw is different, resulting in unevenness; 4. There is an error in the running-in process of the disc, so that the brake pad is not evenly melted into the brake disc; 5. Drag brake or driving habit problems, so that the brake pad is not evenly attached to the brake disc; 6. Other reasons: deformation of the horns and lower swing arm, excessive braking force and frequency, which will lead to overheating of the brake disc and brake pads, and deformation in case of cold are all causes of brake shaking.

It is normal for the new brake disc and brake pads to not run in well, and it is normal for the brakes to shake a little, and they will not shake after running in for a while.

It is not normal for the front wheels to shake when the brake pads and brake discs are applied to the brakes. The reason is: when changing the brake disc, there is rust on the base and it is not cleaned, and you need to go to the repair shop of the car in time to deal with the rust to solve the problem of front wheel shaking.

In daily braking use, the brake disc will generate a lot of heat due to the deceleration friction of the vehicle, and the temperature will be very high. At this time, when I went to wash the car, before the brake disc had time to cool down, the cold water sprayed on the brake disc, causing some damage to the brake disc. Compared with brake pads, the wear and tear of brake discs is relatively slow, and repair shops generally recommend replacing brake pads and brake fluid.

However, the brake disc is worn after a certain period of use, and the surface of the brake disc is uneven or the thickness of the brake disc is not up to standard, which will seriously affect the brake performance in the long run. Do a four-wheel alignment, if you are still shaking, look at the quality of ceramic brake pads;

Hello, if you just changed the brake pads and brake discs, the surface is flat, the brakes should not shake, check the chassis for loose screws. Hope it can help you. I wish you a happy use of the car [Car questions, ask the car master.

Mine is also the brake pads and discs that start to change after the front brake shakes. But the back is still shaking, and the float is a bit big, and it shakes when the brakes are pressed. Do you want to fix this??

Normal, just rub it for a while.

Brake pads do not cause shaking. Most of the reasons for the shaking are due to the deformation of the brake disc in the alternating cold and hot conditions at high temperatures or the warping of the brake disc after re-discing, which has nothing to do with the brake pads. As for why you just change the pair, it is estimated that the reason is that the latter is very compressible, and the product is able to absorb this warpage and deformation of the brake disc.

In the original car supporting standard, compressibility is a very important item, requiring the compressibility of the brake pad to be between millimeters under the normal braking force, so as to ensure the response speed of the brake pad under emergency braking conditions. So, all things considered, if it's good to replace the brake pads because of shaking, you may not be happy.

Hello! Generally, the causes of brake shaking are, brake pads or brake discs are worn unevenly, and slight deformation occurs, resulting in different contact surfaces during work, resulting in shaking.

Yes, this has something to do with the quality of the brake pads, and it is better to replace the brake pads with the original ones, after all, it is related to life safety.

Changed the brake disc, brake or shake?

After changing the brake disc a few times, it may not be because of the problem with the brake disc, but because of the dynamic balance of the wheels. If there is a problem with the dynamic balance of the wheel, it is necessary to carry out a dynamic balance test, which can solve the problem. The braking system is very important for the car, and the braking system is related to the driving stability and driving safety of the car.

Changed the brake disc, brake or shake?

Hello. The reason why the brake disc is still shaking is that there is a problem with the dynamic balance of the wheel, and the dynamic balance test needs to be carried out so that the problem can be solved.

Knowledge supplement: The braking system is very important for the car, which is related to the driving stability and safety of the car. The main components of the brake system are vacuum booster pump, brake master cylinder, brake cylinder, brake pad, brake disc.

Brake discs and pads are wear parts that need to be replaced regularly, and as the car's mileage increases, so do the brake discs and brake pads. The braking device creates friction between the brake pads and the wheel hub or disc, and in the process of friction, the kinetic energy of the car is converted into heat energy and dissipated. Hope it helps.
