Common Problems and Their Solutions about Brake Pads
March 28,2022
Brake pads are an important part of the car braking system, which directly determines the safety performance of the car and should attract everyone's attention. What are the common problems of brake pads? How to solve them?
Common problems and solutions about brake pad
✔️Brake does not return
This phenomenon is that after the brake pedal is stepped on, the pedal does not return to its original position or is relatively slow. Most of the reasons for this phenomenon are that the cylinder piston is stuck due to dirt. It is only necessary to deal with the cylinder piston. Note that the air in the brake pipeline and brake fluid must be drained clean.
✔️Brake softens
The phenomenon of soft brakes is very common, mainly due to insufficient brake fluid, relatively thin brake discs, air in the brake lines, and deterioration of brake fluid. The most common of these are spoiled brake fluid and lack of brake fluid.
✔️Abnormal noise when braking
The abnormal brake noise is mainly due to the brakes being pressed while the vehicle is driving, 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 poor quality of the brake pads, the impurity in the brake pads or rust, etc., in general, stepping on the brakes a few more feet will alleviate the abnormal noise.
Car brake pads refer to the friction materials fixed on the brake drum or brake disc that rotates with the wheels. The friction linings and friction pads are subjected to external pressure and generate friction to achieve vehicle deceleration.
✔️Brake failure
Brake failure is a very serious problem in the car. Generally speaking, the phenomenon of brake failure will not occur unless the car has some quality problems or the braking system fails. Brake failure has more to do with the quality of the car.
What should I do when the brake fails while driving?
First, control the direction according to the speed of the car, gradually reduce the gear and make full use of the engine braking, and gradually lower the speed. When the vehicle speed is lower than 60KM/H, you can consider using the handbrake to slow down (the vehicle speed is too high and accidents may occur).
✔️Spring foot
There are two types of spring feet:
One is when you feel the pedal bounce when you brake hard. This is normal, because ABS helps you release the brake caliper to brake.
The other is abnormal wear of the brake disc, such as uneven lines on the brake disc. This situation can lead to bouncing feet and reduced braking power. The solution is to replace the brake discs and pads as soon as possible.
✔️Brakes hard
Hardening of the brakes is usually the result of the failure of the vacuum brake pump. To make a car of about 1.5 tons generate 1G braking force is not a success with one foot and a little lever principle, but also needs the help of a vacuum brake pump.
The vacuum brake pump has two chambers, one connected to the intake manifold and another connected to the outside atmosphere. When the engine is working, the intake manifold takes in air, the flow rate is fast, and negative pressure is generated, which is a negative pressure chamber. The other positive pressure chamber is connected to the atmosphere. When braking is required, the air pressure difference between the two is used to generate power and the braking force is generated by applying pressure to the brake fluid to rub the brake pads and the brake disc.
If you lose this boost, all the braking force will be applied by your feet.
✔️Brake bias
When braking, the steering wheel deflects and the body deviates from the straight track. That's because of the uneven braking force left and right. That means the brake pads are partially worn or the brake cylinder 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 the intervention of ESP, the brake pads are prone to eccentric wear.
The brake force cylinder is the executive component 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 various unpredictable consequences.
