Brake pads common problems and solutions 1. Brake does not return
This phenomenon is that after the brake pedal is pressed, the pedal does not return to the original position or is relatively slow. The cause of this phenomenon is mostly caused by the stuck piston of the pump due to dirt, as long as the pump piston is processed. After the treatment, the air inside the brake pipe and brake oil must be drained.
Brake pads common problems and solutions 2. Brakes become soft
The phenomenon that the brakes become soft is very common. Many car owners report that this phenomenon exists in their own cars. The reason for this phenomenon is that the brake oil is insufficient, the brake discs are relatively thin, the air in the brake pipe is deteriorated, and the brake oil is deteriorated. The most common of these is the deterioration of brake fluid and the lack of brake fluid.
Brake pads common problems and solutions 3. Abnormal noise when braking
The abnormal noise of the brakes is mainly when the vehicle is driven to brake, and the brake system will emit a sharp metal friction sound (very harsh), which may be due to the thinning of the brake pads, the quality of the brake pads, the foreign matter in the brake pads or the brake discs. Rust, etc., in general, more than a few feet of brakes will be relieved.
Brake pads common problems and solutions 4. Brake failure
Brake failure is a very serious problem for cars. Under normal circumstances, there is no brake failure, unless there are some quality problems in the car or the brake system fails. Needless to say, the reason for the brake failure is related to the quality of the car. What should I do if I encounter a brake failure in a driving car? Of course, this kind of thing is not willing to come across, but in case of such a situation, how to respond? First, according to the speed of the car, the direction is controlled, and the gear is gradually reduced. Using the engine brake, the vehicle speed is gradually lowered. When the vehicle speed is lower than 60KM/H, it can be considered to decelerate with a hand brake (the vehicle speed is too high and it is easy to cause an accident).
Brake pads common problems and solutions 5. Bullet.
There are two situations in the foot:
One is big! Force! When the brakes feel the pedal feels like a foot, this is normal, because ABS helps you to release the brake caliper to brake.
The other is the abnormal wear of the brake disc, such as the unevenness of the brake disc. This situation can cause the foot and the braking force to drop. The solution is to replace the brake discs and brake pads as soon as possible.
Brake pads common problems and solutions 6. Brake hardening
Hardening of the brakes is generally due to the failure of the vacuum brake pump. To make the -1G braking force of a car of about 1.5 tons can be successful without a foot plus a little lever principle, and the vacuum brake pump is needed. The vacuum brake pump has two chambers, one connected to the intake manifold and one connected to the outside atmosphere. When the engine is working, the intake manifold is inflated, the flow rate is fast, and a negative pressure is generated, which is a negative pressure chamber. The other positive pressure chamber is connected to the atmosphere. When the brake is required, the differential pressure between the two is used to generate the braking force by friction between the brake pad and the brake disc by applying pressure to the brake fluid.
If you lose this power, all the braking force will be applied by your feet. This is a lot of pressure for people with kidney deficiency.
Brake pads common problems and solutions 7. Brake bias
When braking, the steering wheel deflected and the body deviated from the straight track. That is because of the uneven braking force on the left and right. That means the brake pad is eccentric or the brake pump is damaged.
The eccentric wear of the brake pads is generally caused by driving habits. If you often make sharp turns in the same direction with ESP intervention, the brake pads are prone to partial wear. (I don't know why you can check the principle of ESP.)
The brake sub-pump is the actuator that is responsible for the distribution of the brake force. If it fails, the four wheels will get the same hydraulic pressure. If the road surface is not ideal, it is easy to have unpredictable consequences.
