The Importance Of The Brake Pads
Driving on the road, the car's power to determine the starting speed, the performance of the brake determines the effect of braking. A driver at the start, due to lack of motivation, was left behind, the mood will inevitably some unhappy, but if the slowdown, because the brake is a problem, lack of braking, and before the car rear-end, full responsibility is certain, At the same time, the car is broken, Brake Pad the mood is more frustrating. Meaning that the performance of the brakes is much more important than the performance of the engine. And when we buy a car, the brake system has been set, the brake pads have become the main components to determine the effect of braking.
The principle of the brake
The working principle of the brake is mainly from the friction, the use of brake pads and brake discs (drums) and tire and ground friction, the vehicle's kinetic energy into the friction after the heat, the car stopped. A well-established braking system must be able to provide a stable, adequate, Brake Pad controllable braking force, and has good hydraulic transmission and cooling capacity to ensure that the driver from the brake pedal of the force can be fully effective to the total pump And the sub-pump, and to avoid high heat caused by hydraulic failure and brake recession.
A new brake pad thickness is generally around 1.5cm, with the use of continuous friction will gradually thinning the thickness. Professional technical staff suggested that when the thickness of the brakes to observe the original thickness of the original 1/3 thickness (about 0.5cm) or so, the owner will increase the frequency of self-test, ready to replace. Of course, individual models due to wheel design reasons, Brake Pad do not have the conditions to see the naked eye, you need to remove the tire to complete.
The importance of brake pads do not need Xiaobian here to say it, but when to replace the brake pads, many people are puzzled, should the maintenance manual should be 30,000 km to replace it? In fact, this intelligence is the reference standard, after all, the situation is not the same as everyone, the road is not the same, resulting in the brake pads are not the same wear and tear. So, Xiao Bian only focus on the moment to discuss the replacement of brake pads? How to see the brake pads should not change?
1, look at the thickness of the brake pads
When the thickness of the brake pads become very thin, the brake performance will be significantly reduced, affecting traffic safety. General new brake pads in the thickness of 1.5cm or so, when the brake pads to wear only 0.5cm, you need to increase the frequency of self-test. When the brake pads are worn to only 0.3cm, be sure to replace it in time, which is the thinnest limit of the brake disc.
2, the brake reaction time and travel
When the brake pads thin, the car's braking reaction will become slow, so the need for deeper and heavier to depress the brakes, in order to achieve the previous braking effect. When you find the brakes before the half-way brake effect is significantly weakened, the brake becomes soft, Brake Pad it is necessary to see whether the brake pads need to be replaced.
3, listen to the sound
Brake discs are mostly iron, after a long time after the park, especially in the rainy days prone to rust, then the brakes will be accompanied by the slightest sound, the sound will be driving for some time after a few feet brake after the disappearance. Can not be improved after a period of time, this time the brake pads must be replaced immediately. Because the limit on both sides of the brake pads have been directly rubbing the brake disc to prove that the brake pads have exceeded the limit. If you really encounter this situation, Brake Pad in the replacement of the brake pads at the same time to meet the brake disc check, there is often the sound of the brake disc has been damaged, even if the replacement of the new brake pads still can not eliminate the sound, Need to replace the brake disc.
4, driving computer tips to replace
General car dashboard with a brake warning light, when the warning light is to remind you to check the brake pads, but the warning light that has been replaced to the limit, and must immediately check. All cars have this warning system, but some are directly sensitive to the thickness of the brake pads, and some are the brake pads have been completely finished, the brake fluid extreme drop will make the warning light.
