Safety is the most important thing when driving vehicles. The same is true for special vehicles. Mixers are a type of special vehicles, mainly used to transport concrete, and are often used on construction sites. The center of gravity of the mixer truck is relatively high, and the road conditions in the driving range are generally poor. Therefore, more attention should be paid to the safety of driving. The brake is one of the most frequently used components on the mixer truck. The quality of the braking performance is very important to the safety of the whole vehicle. , The driver of the mixer truck must learn the skill of judging abnormal brakes, and can't wait for the brakes to fail, otherwise the consequences will be serious. The following editor tells you what conditions indicate that the brakes will have problems.
1. Pay attention to abnormal brakes: When you step on the brakes, the brake system makes a sharp metal friction sound. This may be caused by thinning of the brake pads, brake potholes, foreign objects in the brake pads or rusting of the brake discs. Under normal circumstances The abnormal noise of the brake will be alleviated by stepping on a few more feet.
2. The stroke of the brake pedal becomes longer, which is what we often call the brake becomes softer. The main reason for the longer brake stroke is air in the brake system, lack of brake fluid, leakage, severe brake pad wear, etc.
3. Brake deviation, the phenomenon of brake deviation generally does not occur much, mainly reflected in the obvious deflection of the steering wheel to one side when the brake is stepped on. This phenomenon may be caused by partial wear of the brake pads, a problem with the brake cylinder, etc.
4. When the brakes become hard, many drivers will encounter the problem of hard brakes. The main reason for the hard brakes is the failure of the vacuum booster and the brakes are not assisted, and the brakes are frequently stepped on.
5. Rebound when stepping on the brake. This situation is also common. The brake pedal rebounds when the brake is stepped on. This phenomenon is mostly caused by the uneven surface of the brake disc, the brake pad, and the deformation of the steel ring.
The above are only part of the brake system problems. If you feel that the brakes are not normal during the driving of the mixer truck, you must not be careless. Stop by yourself to check the cause. If you can’t figure it out, go to the repair station for repairs. Don’t delay. Time, otherwise major problems will not be worth the loss.
