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(gè)新剎車(chē)片厚度一般在1.5cm左右，隨著使用中不斷摩擦厚度會(huì)逐漸變薄。專 業(yè)的技術(shù)人員建議，當(dāng)肉眼觀察剎車(chē)片厚度已經(jīng)僅剩原先1/3厚度(約0.5cm)左右時(shí)，司機(jī)就要增加自檢頻率，隨時(shí)準(zhǔn)備更換了。當(dāng)然個(gè)別車(chē)型由于輪轂設(shè)計(jì)原因，不具備肉眼查看的條件，需要拆卸輪胎才能完成。每個(gè)剎車(chē)片的兩側(cè)都有一個(gè)突起的標(biāo)志，這個(gè)標(biāo)志的厚度在兩三毫米左右，這也是剎車(chē)盤(pán)較薄更換的極限，如果剎車(chē)片厚度已經(jīng)與此標(biāo)志平行，則必須要進(jìn)行更換。因此當(dāng)剎車(chē)片厚度接近此標(biāo)志的時(shí)候，司機(jī)就要隨時(shí)觀察準(zhǔn)備了，不過(guò)在不拆卸輪胎的情況下通過(guò)肉眼很難準(zhǔn)確觀察，目前不少車(chē)型在剎車(chē)片過(guò)薄時(shí)儀表手剎燈位置會(huì)有所提示，相對(duì)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.

Tips:

攪拌車(chē)剎車(chē)片根據(jù)用車(chē)環(huán)境和開(kāi)車(chē)習(xí)慣沒(méi)有嚴(yán)格的更換間隔，一般在行駛六萬(wàn)左右就要考慮更換。當(dāng)肉眼觀察發(fā)現(xiàn)攪拌車(chē)剎車(chē)片較薄時(shí)應(yīng)當(dāng)在保養(yǎng)時(shí)要求技術(shù)人員進(jìn)行檢查，因?yàn)槿庋塾^察本來(lái)就會(huì)存在誤差，專 業(yè)的維修站通過(guò)卡尺要比肉眼觀察更嚴(yán)謹(jǐn)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(tīng)聲音

2、 Listen to the sound

如果在輕點(diǎn)攪拌車(chē)剎車(chē)的同時(shí)伴隨有“鐵蹭鐵”的絲絲聲，此時(shí)剎車(chē)片必須立即更換。因?yàn)閿嚢柢?chē)剎車(chē)片兩側(cè)的極限標(biāo)識(shí)已經(jīng)直接摩擦剎車(chē)盤(pán)，證明剎車(chē)片已經(jīng)超過(guò)極限。遇到這種情況，在更換剎車(chē)片的同時(shí)要配合攪拌車(chē)剎車(chē)盤(pán)的檢查，出現(xiàn)這種聲音時(shí)往往攪拌車(chē)剎車(chē)盤(pán)已經(jīng)受到損壞，此時(shí)即便更換新的剎車(chē)片仍然不能響聲，嚴(yán)重時(shí)需要更換剎車(chē)盤(pán)。

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(dāng)聽(tīng)見(jiàn)攪拌車(chē)剎車(chē)有聲音的時(shí)候往往已經(jīng)晚了，此時(shí)攪拌車(chē)剎車(chē)盤(pán)多多少少會(huì)受到損傷。攪拌車(chē)剎車(chē)盤(pán)的相比剎車(chē)片要高出很多，因此建議大家勤檢查攪拌車(chē)剎車(chē)片，避免損傷剎車(chē)盤(pán)的事情出現(xiàn)。

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(jué)力度

3、 Feeling strength

當(dāng)攪拌車(chē)的剎車(chē)片變薄時(shí)我們的剎車(chē)效果會(huì)受到影響，此時(shí)需要更深的踩下制動(dòng)踏板才能達(dá)到原先輕踩就能達(dá)到的制動(dòng)效果，前半程制動(dòng)效果明顯減弱，很多人感覺(jué)自己的攪拌車(chē)剎車(chē)變軟，有點(diǎn)剎不住了，此時(shí)就要檢查攪拌車(chē)剎車(chē)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.
