When we are driving, when there is an emergency, we usually step on the brake quickly. What we are afraid of is the sudden failure of the brake. The danger is unpredictable. The mixer has high requirements for the performance of the vehicle, so the brake pads are also the focus of the inspection. Generally, we will use the following three methods in the self inspection.

一、看厚度

1、 Look at the thickness

一個新剎車片厚度一般在1.5cm左右，隨著使用中不斷摩擦厚度會逐漸變薄。專 業的技術人員建議，當肉眼觀察剎車片厚度已經僅剩原先1/3厚度(約0.5cm)左右時，司機就要增加自檢頻率，隨時準備更換了。當然個別車型由于輪轂設計原因，不具備肉眼查看的條件，需要拆卸輪胎才能完成。每個剎車片的兩側都有一個突起的標志，這個標志的厚度在兩三毫米左右，這也是剎車盤較薄更換的極限，如果剎車片厚度已經與此標志平行，則必須要進行更換。因此當剎車片厚度接近此標志的時候，司機就要隨時觀察準備了，不過在不拆卸輪胎的情況下通過肉眼很難準確觀察，目前不少車型在剎車片過薄時儀表手剎燈位置會有所提示，相對自檢就方便一些。

The thickness of a new brake pad is generally about 1.5cm. With the continuous friction in use, the thickness will gradually become thinner. Professional technicians suggest that when the thickness of the brake pad is only about 1 / 3 of its original thickness (about 0.5cm), the driver should increase the frequency of self inspection and be ready to replace it at any time. Of course, due to the design of the wheel hub, individual models do not have the conditions for visual inspection, so they need to dismantle the tire to complete. There is a protruding mark on both sides of each brake pad. The thickness of the mark is about two or three millimeters, which is also the limit of replacing the thin brake disc. If the thickness of the brake pad is parallel to the mark, it must be replaced. Therefore, when the thickness of the brake pad is close to this mark, the driver should be ready to observe at any time. However, it is difficult to observe accurately by naked eyes without removing the tire. At present, many models will prompt the position of the instrument hand brake light when the brake pad is too thin, which is more convenient for self inspection.

攪拌車剎車片根據用車環境和開車習慣沒有嚴格的更換間隔，一般在行駛六萬公里左右就要考慮更換。當肉眼觀察發現攪拌車剎車片較薄時應當在保養時要求技術人員進行檢查，因為肉眼觀察本來就會存在誤差，專 業的維修站通過卡尺要比肉眼觀察更嚴謹一些。

There is no strict replacement interval for the brake pads of the mixer according to the vehicle environment and driving habits. Generally, the replacement should be considered when driving about 60000 km. When it is found that the mixer brake pad is thin by visual observation, the technician should be required to check it during maintenance, because there will be errors by visual observation, and the professional maintenance station should be more rigorous than visual observation through caliper.
                 

二、聽聲音

2、 Listen to the sound

如果在輕點攪拌車剎車的同時伴隨有“鐵蹭鐵”的絲絲聲，此時剎車片必須立即更換。因為攪拌車剎車片兩側的極限標識已經直接摩擦剎車盤，證明剎車片已經超過極限。遇到這種情況，在更換剎車片的同時要配合攪拌車剎車盤的檢查，出現這種聲音時往往攪拌車剎車盤已經受到損壞，此時即便更換新的剎車片仍然不能消除響聲，嚴重時需要更換剎車盤。

If there is the sound of "iron rubbing against iron" when the mixer brakes gently, the brake pads must be replaced immediately. Because the limit marks on both sides of the mixer brake pad have directly rubbed the brake disc, which proves that the brake pad has exceeded the limit. In this case, when replacing the brake pads, it is necessary to cooperate with the inspection of the mixer brake disc. When this sound occurs, the mixer brake disc is often damaged. At this time, even if the new brake pads are replaced, the noise can not be eliminated, and the brake disc needs to be replaced in serious cases.

Tips:

當聽見攪拌車剎車有聲音的時候往往已經晚了，此時攪拌車剎車盤多多少少會受到損傷。攪拌車剎車盤的價格相比剎車片要高出很多，因此建議大家勤檢查攪拌車剎車片，避免損傷剎車盤的事情出現。

When you hear the sound of the mixer brake, it is often too late. At this time, the mixer brake disc will be more or less damaged. The price of the mixer brake disc is much higher than that of the brake pad. Therefore, it is recommended that you check the mixer brake disc frequently to avoid damaging the brake disc.

三、感覺力度

3、 Feeling strength

當攪拌車的剎車片變薄時我們的剎車效果會受到影響，此時需要更深的踩下制動踏板才能達到原先輕踩就能達到的制動效果，前半程制動效果明顯減弱，很多人感覺自己的攪拌車剎車變軟，有點剎不住了，此時就要檢查攪拌車剎車片是否需要更換了。

When the brake pads of the mixer become thinner, our braking effect will be affected. At this time, we need to step on the brake pedal more deeply to achieve the braking effect that can be achieved by lightly stepping on the brake pedal. The braking effect of the first half of the journey is obviously weakened. Many people feel that their brakes of the mixer become soft and can't stop. At this time, we need to check whether the brake pads of the mixer need to be replaced.
