The brake pad can directly reflect the braking effect, so the brake pad is a key component in the automobile braking system. The brake pad is generally composed of floor, adhesive heat insulation layer and friction layer. The heat insulation layer of the brake pad is composed of poor heat conduction materials and reinforcing materials, and the friction layer of the brake pad is composed of reinforcing materials, adhesives and fillers. Generally, the piston hydraulically driven in the brake caliper is used to push the contact friction between the brake pad and the brake disc or drum into heat energy, so as to achieve the function of deceleration braking.
 

首先要檢查所換剎車片是否是純正配件，產品包裝的完好性、防偽標志及包裝標識與剎車片上的標識是否一致，產品型號是否和合格證內容相符。在將車輛舉升這前，應先將盛放剎車油的覆蓋打開，輪胎螺絲應對角松動。如果使用簡易千斤頂支撐時，應將千斤頂支好，并加固不更換剎車片的輪子。將輪胎卸下，松開鉗體緊固螺釘，并檢查螺釘、鉗滑動導桿，清除上面的泥沙及油污，并上潤滑油保養。將舊剎車片拆下，檢查剎車盤的磨損程度，是否起溝起糟。嚴重磨損應更換新的剎車盤，其周期為8—12萬公里，否則會加快新更換的剎車片的磨損，且制動時方向抖動，制動力過校

First, check whether the replaced brake pad is a pure accessory, whether the integrity of the product packaging, anti-counterfeiting marks and packaging marks are consistent with the marks on the brake pad, and whether the product model is consistent with

 the contents of the certificate. Before lifting the vehicle, open the cover containing brake oil and loosen the tire screws diagonally. If a simple jack is used for support, the jack shall be well supported and the wheels without replacing the brake pads shall be reinforced. Remove the tire, loosen the fastening screw of the tong body, check the screw and the sliding guide rod of the Tong, remove the sediment and oil stain on it, and apply lubricating oil for maintenance. Remove the old brake pad and check the wear degree of the brake disc for groove and mess. If the brake disc is seriously worn, it shall be replaced with a new one with a cycle of 80000-120000 km, otherwise the wear of the newly replaced brake pad will be accelerated, the direction will shake and the braking force will be over calibrated during braking

安裝新剎車片應分清內外，剎車片的磨擦面應向剎車盤，使盤片配合合適。安好附件，緊固鉗體。在緊固鉗體前，應用工具將鉗上的塞推回位，以便于將鉗安裝到位。如果需要更換鼓式制動器上的剎車片建議到維修廠請人員操作，以免出現差錯。

When installing a new brake pad, the inside and outside shall be distinguished, and the friction surface of the brake pad shall face the brake disc to make the disc fit properly. Install the accessories and fasten the clamp body. Before tightening the tong body, push the plug on the Tong back with a tool to facilitate the installation of the Tong in place. If the brake pad on the drum brake needs to be replaced, it is recommended to go to the maintenance plant for operation to avoid errors.
