制動失靈包括制動踏板行程過大，制動作用遲緩，制動效能很低甚至喪失，制動距離增長。對此故障的排除方法有三種，下面濟南沃爾沃汽車專修廠家為您解答。

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.剎車片磨損嚴(yán)重。

1. The brake lining is seriously worn.

剎車片表層摩擦塊磨損嚴(yán)重，車輛制動時，剎車片底部鋼板與剎車盤摩擦，會導(dǎo)致車輛制動性能下降。維修技師使用舉升機將車輛舉起，拆下車輪，檢查剎車片的厚度；如果剎車片過薄，可確認(rèn)是磨損嚴(yán)重，從而造成了剎車剎不住的情況。

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.

更換剎車片。剎車片屬于耗材，不在車輛質(zhì)保范圍內(nèi)，車主需要自費！

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.剎車分泵故障。

2. The brake wheel cylinder is faulty.

車輛制動時，剎車分泵推動剎車片完成車輛制動過程。剎車分泵故障，會導(dǎo)致其無法推動剎車片與剎車盤實現(xiàn)車輛制動效果。維修技師使用舉升機將車輛舉起，拆下車輪，檢查剎車分泵是否有開裂、漏油等現(xiàn)象；如果有上述現(xiàn)象，即可確認(rèn)剎車分泵出現(xiàn)故障。剎車分泵故障，會導(dǎo)致踩剎車的時候壓力傳輸不下去，進而出現(xiàn)剎車失靈的情況。

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.

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

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.剎車助力鼓漏氣。

3. The brake booster drum leaks.

剎車助力鼓可幫助駕駛員對剎車系統(tǒng)施加額外的制動力，進一步縮短剎車距離，保障車輛行駛安全。如果剎車助力鼓漏氣，會導(dǎo)致車輛剎車輔助功能失效，車輛制動能力降低。維修技師打開引擎艙，檢查剎車助力鼓管道接口是否發(fā)生松動。

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.

重新緊固剎車助力鼓管道接口。車輛在質(zhì)保期內(nèi)，可到4S店免費處理；車輛超出質(zhì)保期，具體費用可來詳細咨詢。

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，我們建議車主：定期保養(yǎng)車輛，及時更換達到使用壽命的零部件。這一方面真的要重視起來，畢竟關(guān)系到人員的安全，更多相關(guān)信息就來我們網(wǎng)站http://www.tbyt.com.cn進行咨詢吧！
