Brake pads are consumables, which will wear out gradually in use. When they are worn to the limit position, they must be replaced. Otherwise, the braking effect will be reduced, and even safety accidents will be caused.

制动刹车片关乎生命，必须谨慎对待。

The brake pad is related to life safety and must be treated with caution.

大多数轿车采用前盘后鼓式制动器结构，一般情况下前制动蹄片磨损的相对较快，后制动刹车片使用的时间相对较长，在日常的检查维护中应注意以下几个方面：

Most cars adopt the structure of front disc and rear drum brake. Generally, the wear of front brake shoes is relatively fast, and the service time of rear brake shoes is relatively long

1.正常行驶条件下每行驶5000对制动蹄片检查一次，不仅要检查剩余的厚度，还要检查刹车片磨损的状态，两边磨损的程度是否一样，回位是否自如等，发现不正常情况必须立即处理。

1. Under normal driving conditions, check the brake shoes every 5000 km, not only check the remaining thickness, but also check the wear state of the brake pads, whether the wear degree on both sides is the same, whether the return is free, etc. if any abnormal situation is found, it must be dealt with immediately.

2.制动刹车片一般由铁衬板和摩擦材料两部分组成，一定不要等摩擦材料部分都磨没了才更换蹄片。例如捷达车的前制动蹄片，新片的厚度为14毫米，而更换的极限厚度是7毫米，其中包括3毫米多的铁衬板厚度和近4毫米的摩擦材料厚度。一些车辆带有制动蹄片报警功能，一旦达到了磨损极限，仪表会报警提示更换蹄片。达到了使用极限的刹车片必须更换，即使尚能使用一段时间，也会降低制动的效果，影响行车的。

2. The brake pad is generally composed of iron lining and friction material. Do not replace the shoe until the friction material is worn out. For example, for the front brake shoe of Jetta, the thickness of the new brake shoe is 14mm, while the limit thickness for replacement is 7mm, including more than 3mm iron lining thickness and nearly 4mm friction material thickness. Some vehicles are equipped with brake shoe alarm function. Once the wear limit is reached, the instrument will give an alarm and prompt to replace the brake shoe. The brake pads that have reached the service limit must be replaced. Even if they can still be used for a period of time, the braking effect will be reduced and the driving safety will be affected.

3.更换时要换原厂备件提供的刹车片，只有这样，才能使刹车片和刹车盘之间的制动效果更好，磨损更小。

3. Replace the brake pads provided by the original spare parts. Only in this way can the braking effect between the brake pad and the brake disc be the best and the wear be the least.

4.更换刹车片时必须使用专用工具将制动分泵顶回。不能用其他撬棍硬压回，这样易导致制动钳导向螺丝弯曲，使刹车片卡死。

4. When replacing the brake pads, special tools must be used to push back the brake cylinder. It is not allowed to press back with other crowbars. This will easily cause the guide screw of brake caliper to bend and block the brake pad.

5.更换刹车片后，一定要踩几脚刹车，以蹄片与制动盘的间隙，造成脚没刹车，易出现事故。

5. After replacing the brake pads, be sure to step on a few brakes to eliminate the gap between the shoe and the brake disc, so that the first foot doesn't brake, which is prone to accidents.

6.制动刹车片更换后，需磨合200方能达到的制动效果，刚换的刹车片须谨慎行驶。

6. After the replacement of the brake pads, it is necessary to run in 200 km to achieve the best braking effect. The newly replaced brake pads must be driven carefully.
