制動(dòng)失靈包括制動(dòng)踏板行程過(guò)大，制動(dòng)作用遲緩，制動(dòng)效能很低甚至喪失，制動(dòng)距離增長(zhǎng)。對(duì)此故障的排除方法有三種，下面濟(jì)南沃爾沃汽車(chē)專(zhuān)修廠(chǎng)家為您解答。

Brake failure includes excessive brake pedal travel, slow braking, low or even loss of braking efficiency, and increased braking distance. There are three troubleshooting methods for this problem. Now, the manufacturer specialized in Volvo Cars in Jinan will answer the question for you.

1.剎車(chē)片磨損嚴(yán)重。

1. The brake lining is seriously worn.

剎車(chē)片表層摩擦塊磨損嚴(yán)重，車(chē)輛制動(dòng)時(shí)，剎車(chē)片底部鋼板與剎車(chē)盤(pán)摩擦，會(huì)導(dǎo)致車(chē)輛制動(dòng)性能下降。維修技師使用舉升機(jī)將車(chē)輛舉起，拆下車(chē)輪，檢查剎車(chē)片的厚度；如果剎車(chē)片過(guò)薄，可確認(rèn)是磨損嚴(yán)重，從而造成了剎車(chē)剎不住的情況。

The friction block on the surface of the brake pad is seriously worn. When the vehicle brakes, the steel plate at the bottom of the brake pad rubs with the brake disc, which will lead to the decline of the vehicle's braking performance. The maintenance technician lifts the vehicle with a lift, removes the wheels, and checks the thickness of the brake pads; If the brake pads are too thin, it can be confirmed that they are seriously worn, which causes the brake failure.

更換剎車(chē)片。剎車(chē)片屬于耗材，不在車(chē)輛質(zhì)保范圍內(nèi)，車(chē)主需要自費(fèi)！

Replace the brake pads. The brake pads are consumables and are not covered by the vehicle warranty. The owner needs to pay for them!

2.剎車(chē)分泵故障。

2. The brake wheel cylinder is faulty.

車(chē)輛制動(dòng)時(shí)，剎車(chē)分泵推動(dòng)剎車(chē)片完成車(chē)輛制動(dòng)過(guò)程。剎車(chē)分泵故障，會(huì)導(dǎo)致其無(wú)法推動(dòng)剎車(chē)片與剎車(chē)盤(pán)實(shí)現(xiàn)車(chē)輛制動(dòng)效果。維修技師使用舉升機(jī)將車(chē)輛舉起，拆下車(chē)輪，檢查剎車(chē)分泵是否有開(kāi)裂、漏油等現(xiàn)象；如果有上述現(xiàn)象，即可確認(rèn)剎車(chē)分泵出現(xiàn)故障。剎車(chē)分泵故障，會(huì)導(dǎo)致踩剎車(chē)的時(shí)候壓力傳輸不下去，進(jìn)而出現(xiàn)剎車(chē)失靈的情況。

When the vehicle brakes, the brake wheel cylinder pushes the brake pad to complete the vehicle braking process. The failure of the brake wheel cylinder will cause it to be unable to push the brake pad and brake disc to achieve the vehicle braking effect. The maintenance technician lifts the vehicle with a lift, removes the wheels, and checks the brake wheel cylinder for cracks, oil leaks, etc; If the above phenomena are found, it can be confirmed that the brake wheel cylinder is faulty. The failure of the brake wheel cylinder will lead to the failure of pressure transmission when the brake is pressed, which will lead to the failure of the brake.

更換剎車(chē)分泵。車(chē)輛在質(zhì)保期內(nèi)，可到4S店免費(fèi)更換；車(chē)輛超出質(zhì)保期，4S店的更換費(fèi)用存在。

Replace the wheel brake cylinder. The vehicle can be replaced at the 4S store for free within the warranty period; The car is out of warranty, and the 4S store has replacement fees.

3.剎車(chē)助力鼓漏氣。

3. The brake booster drum leaks.

剎車(chē)助力鼓可幫助駕駛員對(duì)剎車(chē)系統(tǒng)施加額外的制動(dòng)力，進(jìn)一步縮短剎車(chē)距離，保障車(chē)輛行駛安全。如果剎車(chē)助力鼓漏氣，會(huì)導(dǎo)致車(chē)輛剎車(chē)輔助功能失效，車(chē)輛制動(dòng)能力降低。維修技師打開(kāi)引擎艙，檢查剎車(chē)助力鼓管道接口是否發(fā)生松動(dòng)。

The brake booster drum can help the driver to apply additional braking force to the brake system, further shorten the braking distance, and ensure the driving safety of the vehicle. If the brake booster drum leaks, it will lead to the failure of the vehicle's brake assist function and the reduction of the vehicle's braking capacity. The maintenance technician opens the engine compartment and checks whether the pipe interface of the brake booster drum is loose.

重新緊固剎車(chē)助力鼓管道接口。車(chē)輛在質(zhì)保期內(nèi)，可到4S店免費(fèi)處理；車(chē)輛超出質(zhì)保期，具體費(fèi)用可來(lái)詳細(xì)咨詢(xún)。

Retighten the pipe interface of the brake booster drum. The vehicle can be handled at the 4S store for free within the warranty period; The vehicle is out of warranty. Please consult us for specific fees.

另外，我們建議車(chē)主：定期保養(yǎng)車(chē)輛，及時(shí)更換達(dá)到使用壽命的零部件。這一方面真的要重視起來(lái)，畢竟關(guān)系到人員的安全，更多相關(guān)信息就來(lái)我們網(wǎng)站http://www.yiyili.com進(jìn)行咨詢(xún)吧！

In addition, we recommend that owners regularly maintain their vehicles and timely replace parts that have reached their service life. This aspect really needs attention. After all, it is related to the safety of personnel. More relevant information will come to our website http://www.yiyili.com Consult!
