How often to replace car brake pads
Generally speaking, the service life of the front wheel brake pads is about 40,000 kilometers, and the service life of the rear wheel brake pads is about 80,000 kilometers (this is because the center of gravity of the car will tilt forward when braking). Every 5,000 kilometers. Check the brake pads. But if you encounter these 3 signs while driving, you should pay more attention!
1. Brake pad thickness
Generally, the thickness of new brake pads is about 1.5cm. When the brake pads are worn to only 0.5cm, It’s almost time to replace it. There is a raised mark on both sides of each brake pad. The thickness of this mark is about two to three millimeters. If the thickness of the brake pad has become parallel to this mark, it must be replaced. On some higher-end models, the position of the handbrake light on the instrument panel will indicate when the brake pads are too thin.
2. Abnormal brake noise
When applying the brakes, try to listen to the sound of the brakes. If you hear a sharp sound like iron grinding iron, When there is a sound, you should pay attention. The limit marks on both sides of the brake pad have directly rubbed against the brake disc, proving that the brake pad has exceeded the limit and must be replaced at this time.
3. Braking response and distance
When the brake pads become thinner, the car’s braking response will also become slower, requiring deeper and heavier steps. Only by braking can the previous braking effect be achieved. When you find that the braking effect is significantly weakened in the first half of the braking process, the brakes become soft, and it is a bit difficult to brake, you should check whether the brake pads need to be replaced.
How to replace brake pads
Since each driver applies the brakes differently, it is difficult to determine how often the brake pads need to be replaced. The only way is to check the degree of wear of the brake pads during routine inspections. If it reaches the critical point, it must be replaced immediately.
Replacement of disc brake pads is relatively simple. Remove the tire, loosen the screws of the brake caliper, remove the brake pad, and replace it with a new one. The whole process takes at least 5 minutes and does not require any adjustment.
Replacement of drum brakes is slightly more difficult. You need to remove the wheel and then the brake drum before replacing the brake pads. Pay attention to the overlap between the new brake pads and the brake drum. If the overlap is incorrect, Okay, sometimes it needs to be polished; when assembling, the gap between the brake pads and the brake drum needs to be adjusted. In short, this is a slightly technicalcontent work.
Correct driving style can make the brake pads last longer
If you encounter any problem, slam on the brakes. This is the favorite of people with poor driving skills. , but in fact it is also a hidden danger of accidents. I believe you may have had this experience: the car in front of you was going well and there was nothing wrong with the road ahead, but someone inexplicably applied the brakes, catching the car behind you off guard and causing a rear-end collision. This is a typical street killer.
In addition, there are people who have only two choices when driving: gas or brake. The frequency of braking reaches a very high level. In fact, such people are not a minority. The result of this is that the brake pads must be replaced every 20,000 to 30,000 kilometers.
The correct way to drive is to pay full attention at all times, keep an eye on the road, stop the gas and slow down in advance if there is a problem, and decide whether to apply the brakes according to changes in the situation. Doing so will save gas and extend the life of the brake pads.
