The brake pad is not satisfied with the brake disc

 If the brake pad is not satisfied with the brake disc it will not cause an increase in braking distance. The quality of the brake disc and the design requirements are comparable, if not adjusted in time, it will cause serious consequences of poor braking. We all know that the vehicle brake system is a complex brake system composed of brake pads, brake drums, springs, brake calipers and so on. It is composed of brake pads, brake disc and ABS brake system. Because the brake pad is thin and elastic, easy to wear, so the brake disc is also very fragile, the role of the brake disc is to transfer the force on the wheel to the brake system to ensure that the car stops. Brake pad through the friction between the friction sheet and the brake disc, so that the brake disc brake action: the friction between the car's driving resistance and the brake disc is called the brake effect. When the brake pad is too thick or too thin, the braking effect will decline, at this time the brake will become more difficult, which also makes the brake system easy to fail, so in daily driving must pay attention to the use of the brake pad. The brake disc is like the shock absorber on the wheel after people get older, the phenomenon of aging deterioration will affect the braking effect and the performance of the brake disc will be affected, resulting in the deterioration of the performance of the brake system and brake problems are inevitable. So in peacetime also pay attention to replace the brake pad and brake disc regularly ah brake system! To keep us safe on the road. The brake pad creates heat with the brake pad or the disc friction pad and it heats the brake pad and it makes the grooves in the brake pad bigger and it's quieter and it's faster and it stops a little bit longer but it also causes a lot of damage to the vehicle. In general, when the brake pad and the brake pad or the brake pad wear or friction between the sparks will produce a lot of smoke and dust, brake fluid can be said to be the main component of the brake pad is the brake pad its role is to brake and reduce the brake reaction speed and braking force. When the pressure in the brake system reaches a certain level, the brake system will emit a harsh brake sound, and there will be a harsh ring. If the brake is abnormal and the brake pad is too thin, it is likely to brake failure and cause an accident. So how do you deal with it?

1. Check the thickness of brake pads
The normal thickness of the brake pad is about 3 mm. If the brake pad on the brake disc is too thick or too thin or damaged, the braking effect will be affected. Some cars have problems in the choice of brake fluid or brake fluid. If the brake pedal is found to be very hard when replaced, it should be replaced in time. Check the brake fluid replacement frequency: because many vehicles at the brake of the metal frame has appeared wear phenomenon, so the owner must pay attention to check the brake fluid (such as brake oil) in the daily maintenance of whether there is a problem. If there is no problem with the brake fluid then it will be easier to replace the brake system once. Checking for low tire pressure can lead to reduced brake pad thickness resulting in poor braking or longer braking distance.
2. Observe the travel state of the brake pedal
When stepping on the brake, if it is found that the pedal height drops, and it is deep stepping, it means that the travel of the brake pedal is not normal, and the need to check and repair in time. The inspection method is also very simple and crude, that is, first step on the brake and then look at the button. If it is a downhill situation, it can not be stepped on suddenly, and the button height is high, it should be checked and repaired immediately. If the height of the button is too high in the normal position, the height of the button can be lowered appropriately to solve the problem. If the button position is too low, there will be a "da da da" sound. Generally, the sound will taper off as the engine speeds reach 3000 RPM. But if you suddenly press the brake pedal while going downhill, there may be no sound.
3. Correct adjustment of brake pad thickness and friction coefficient
The friction coefficient of car brake pads is usually between 0.7 and 0.9, but different models have their differences, some models of friction coefficient is larger, some models are smaller. Also pay attention to is whether the brake pad need to be replaced? This can not be judged by the naked eye alone, it depends on the actual situation to decide. After the correct replacement or adjustment of the brake pad, the travel of the brake pedal should be longer than before the replacement. For example: the same distance, some owners replace the front brake pedal distance is longer, and some owners change the rear brake pedal travel is shorter, the reason is the brake pedal travel is affected when the brake pad and friction between the brake pad and the wheel caused by. So pay attention to check the brake system before using the brake brake.
